Uma máscara de solda protege o circuito de cobre, enquanto termina como HASL, Concordar, ou OSP aumentam a resistência à oxidação e a soldabilidade.
Montagem de componentes & Teste
Os componentes são montados via SMT ou métodos de furo passante. As placas finais passam por testes elétricos e mecânicos para garantir funcionalidade, confiabilidade, e resistência mecânica.
Dimensões & Forma
A PCB deve caber precisamente na estrutura do dispositivo. Eletrônica compacta, como smartphones ou wearables, costumam usar formas personalizadas ou curvas para otimizar o espaço interno.
Grossura
A espessura da camada metálica depende das necessidades mecânicas – dispositivos industriais podem exigir aço inoxidável de 1–2 mm, enquanto os eletrônicos portáteis favorecem o alumínio de 0,5–1 mm para peso reduzido. A espessura do substrato também afeta a rigidez, custo, e desempenho do sinal, então o equilíbrio é fundamental.
Otimização de layout
Os componentes geradores de calor devem ser colocados próximos à camada metálica para uma transferência de calor eficiente. Peças sensíveis ou de alta frequência devem ser isoladas ou blindadas para minimizar EMI. Os planos de terra e o roteamento de rastreamento otimizado melhoram a compatibilidade eletromagnética e a integridade do sinal.

Smt (Tecnologia de montagem de superfície) outsourcing is a core collaboration model in the field of electronic manufacturing, involving multiple precise stages such as Montagem da PCB, de solda, and inspection. Providing complete and standardized documentation not only helps the manufacturer quickly understand project requirements and offer accurate quotations, but also prevents rework, delays, or even product failures caused by technical discrepancies. Whether it’s a small pilot production for a startup or large-scale manufacturing for an established company, preparing all necessary documents in advance is the key to ensuring an efficient SMT production partnership.
Below are the four essential categories of documentation required before initiating SMT cooperation—covering the full process from project setup to mass production:
This serves as the manufacturer’s “first-hand reference” to confirm the project scope and basic product attributes, helping avoid misunderstandings later in production.
Project Brief
Key contents: Project name, cooperation type (prototype / produção em massa / urgent order), expected order quantity (per batch or monthly demand), cronograma de entrega, and target price range (opcional).
Notas: Specify whether PCB fabrication and component sourcing are included (turnkey / remessa). For turnkey projects, indicate preferred component brands (Por exemplo, Yageo, Murata) or quality grades (industrial / consumer).
Basic Product Parameters

PCB Layout source files (opcional; Alto, Almofadas, etc., for footprint and layout verification);
PCB specification sheet: indicate material (Por exemplo, FR-4, Rogers), grossura (Por exemplo, 1.6 mm), number of layers (solteiro / dobro / multicamadas), surface finish (Sangrar / Concordar / Osp), cor da máscara de solda, and silkscreen color.
Notas: If the PCB is to be sourced by the manufacturer, provide supplier information or purchase standards. If supplied by the customer, indicate the PCB batch number and storage conditions (to prevent moisture or oxidation).
Component Documentation
Arquivos necessários:
Bom (Lista de materiais): Include part numbers, full component models (Por exemplo, 0402 100 nF 16 V X7R), especificações (package size, capacitance/resistance, tolerância, voltage/current rating), quantidade (per board + wastage rate, suggested 5–10%), and optional substitutes.
Datasheets (for key components): ICS, conectores, and special parts with pin definitions, soldering temperature, and storage conditions.
Component package library: For special packages (Por exemplo, Mf, BGA, 01005), provide packaging files (IPC standard or 3D model) to ensure accurate placement.
Notas: BOMs should be in Excel format, marking “key components” (Por exemplo, main ICs) separately for prioritized procurement. If components are supplied by the customer, provide part list, batch numbers, and packaging details (reel / tube / tray).
Assembly and Soldering Process Files
Arquivos necessários:
Pick and Place File: CSV/TXT format with reference designators, X/Y coordinates, rotation angles, and package types, fully matching the Gerber and BOM.
Stencil File: If the stencil is to be produced by the manufacturer, provide Gerber data or specify aperture parameters (Por exemplo, opening ratio, anti-bridging design).
Soldering process requirements: Define soldering method (reflow / wave), solder profile (Por exemplo, Sn-Ag-Cu for lead-free), and cleaning process (no-clean / water-clean / solvent-clean).
Notas: For fine-pitch devices such as BGA or QFP, include “rework process requirements” (Por exemplo, hot-air temperature, repair steps). If special soldering processes are needed (Por exemplo, sem chumbo, low-temperature), specify them in advance.
These documents define the production process and inspection standards, helping the manufacturer quickly set up production lines and establish an appropriate quality control plan.
Production Process Requirements
Key contents: Whether first article inspection (FAI) é necessário; approval process for the first sample (Por exemplo, mass production only after customer sign-off); in-process inspection frequency (Por exemplo, once per hour); batch traceability requirements (Por exemplo, linking component batch numbers with product batches).
Notas: For small-scale pilot runs, specify whether a “trial production report” is needed — including yield rate, defect analysis, and process improvement suggestions.
Testing Standards and Equipment Requirements
Arquivos necessários:
Inspection checklist: Define mandatory tests such as AOI (Inspeção óptica automatizada), Raio X (for BGA and hidden joints), TIC (Teste no circuito), Fct (Teste funcional), and aging tests.
Inspection standards: Include AOI defect judgment criteria (Por exemplo, acceptable bridge, insufficient solder limits) and FCT functional test points (tensão / atual / signal parameters).
Test fixture design: For FCT testing, provide test fixture design files (Por exemplo, Gerber, test point coordinates) or request the manufacturer to design them (specify requirements clearly).
Notas: For functional testing, supply test programs (Por exemplo, LabVIEW scripts) or test cases, outlining test steps and pass criteria (Por exemplo, voltage range 3.3V ± 0.1V). If special industry tests are required (Por exemplo, RoHS verification, ESD testing), inform the manufacturer in advance.
Packaging and Labeling Requirements
Key contents: Packaging method (Por exemplo, anti-static bag, tray, carton), material specifications (anti-static grade), labeling details (model, batch number, production date, quality mark), and moisture/shock protection (Por exemplo, desiccants, foam padding).
Notas: For export products, specify if packaging must meet international shipping standards (Por exemplo, ISTA 1A) and whether customs codes or CE/FCC labels are required.
For specific industries or export products, relevant compliance documents are required to ensure adherence to industry standards and market entry regulations.
Quality System Documentation
Key contents: If the customer enforces a quality management system, provide their quality manual or specify which standards the manufacturer must follow (Por exemplo, ISO 9001, IATF 16949). For automotive or medical products, include a “Quality Risk Assessment Report” (Por exemplo, FMEA).
Compliance and Certification
Key contents: Industry certifications required (Por exemplo, Rohs, ALCANÇAR, Ul, CE), and whether the manufacturer must assist in certification (Por exemplo, providing samples or test data). If certifications already exist, provide copies for reference to align production processes.
Notas: For RoHS compliance, specify whether a “RoHS label” is required and if any restricted substances (Por exemplo, liderar, cádmio) must be controlled. For medical electronics, provide relevant “Medical Device Registration” information to ensure conformity with regulatory standards.
Inconsistent data: The most common problems include mismatched component models between the BOM and placement file, or discrepancies between Gerber files and PCB specifications (Por exemplo, espessura da placa). It’s recommended to cross-check the three core files — BOM, Gerber, and Pick & Place file — in advance.
Non-standard file formats: Using non-standard coordinate file formats or incomplete Gerber layers prevents direct use by the manufacturer. Always follow standard formats (Gerber RS-274X, coordinate CSV).
Missing key information: Omitting soldering temperature profiles or unclear testing standards can lead the manufacturer to follow default parameters, which might not meet your requirements. Verify each item against the “Technical Document Checklist” to avoid omissions.
Outdated documentation: For any design updates during cooperation, issue a formal “Change Notice” specifying the modification details and effective date to prevent production based on old revisions.
The essence of SMT outsourcing lies in precise alignment — manufacturers rely on documents to understand customer expectations, while customers rely on documents to guarantee product quality.
The checklist above covers every essential document, from basic information to compliance records. It is recommended to organize all materials by category and confirm their accuracy with the manufacturer’s technical team before project kickoff.
If you encounter difficulties during document preparation (Por exemplo, BOM optimization or process documentation), consult your manufacturer’s technical support team. Early communication helps resolve potential issues and ensures smoother, more efficient SMT collaboration.

The air conditioner that automatically adjusts room temperature in a smart home, the sensor that monitors soil moisture in farmland, the monitoring device on a factory line that predicts equipment failures—despite their different appearances, all these Internet of Things (IoT) devices share the same electronic heart: the printed circuit board assembly (PCBA). How do they sense the world, process information, and execute commands? And how are they created in the factory? Let’s uncover the operational secrets and manufacturing process that transform IoT devices from “nerve endings” to “intelligent brains.”
IoT devices are smart devices equipped with sensors, communication modules, and other technologies that can connect to networks (such as the internet or local networks) and exchange data. They are widely used in smart homes, industrial monitoring, and smart cities. Their core feature is interconnectivity, enabling remote control, automatic data collection, and intelligent decision-making.
A PCB (Placa de circuito impresso), known as the “central nervous system” of electronic devices, provides both the physical support for components and the essential circuitry connections. An IoT device PCB is a specially designed printed circuit board tailored to the needs of IoT applications, acting as the physical carrier that links the perception layer, network layer, and application layer of the IoT ecosystem.
Compared with PCBs in consumer electronics or industrial control systems, IoT PCBs deliver unique value in three dimensions:
Adaptability to pervasive connectivity: They must support stable integration of multiple communication modules such as Wi-Fi, Bluetooth, LoRa, and NB-IoT, ensuring seamless data transmission between devices and the cloud, as well as device-to-device communication.
Low power consumption: Since most IoT devices rely on battery power, the PCB’s circuit design and material selection directly affect energy efficiency and battery life.
Versatility across deployment environments: IoT PCBs must maintain reliability under challenging conditions such as high temperature, umidade, electromagnetic interference, ou vibração. This includes workshop equipment in industrial IoT, soil sensors in agricultural IoT, and wearable devices in smart healthcare applications.
The diversity of IoT devices and the complexity of their applications mean that IoT Manufatura de PCB must meet multiple requirements, mainly in the following areas:
IoT devices often aim for lightweight designs, such as fitness bands and compact environmental sensors, which require PCBs to deliver maximum functionality within limited space. Modern IoT PCBs commonly adopt HDI (Interconexão de alta densidade) tecnologia, with line width and spacing below 0.1 mm. By using blind and buried vias, they minimize redundant layers and achieve 2–3 times the component density of traditional PCBs within the same footprint.
Power efficiency is the lifeline of IoT devices. PCB manufacturing supports energy optimization in two ways:
Seleção de materiais: Using substrates with low dielectric constant (Dk) and low dissipation factor (Df), such as modified FR-4 or PTFE, to reduce energy loss during signal transmission.
Circuit layout: Optimizing power plane design, minimizing parasitic parameters, and isolating analog from digital circuits, which all help reduce static power consumption.
Different application scenarios impose stringent environmental requirements:
Industrial IoT: Withstand temperature cycles from –40℃ to 125℃ and electromagnetic interference above 1000V.
Agricultural IoT: Resist high humidity (≥90% relative humidity) and chemical corrosion (Por exemplo, pesticides, soil acidity/alkalinity).
Outdoor IoT: Provide UV resistance, waterproofing, and dustproofing (IP67 and above).
To meet these needs, PCB manufacturing employs surface finishes like ENIG or ENEPIG to enhance corrosion resistance and uses high-glass-fiber substrates to improve mechanical strength.
IoT deployments often involve large-scale rollouts, such as millions of sensor nodes in smart cities. As a core component, the PCB must balance performance and cost. Manufacturers achieve this by:
Optimizing board design to reduce material waste.
Applying standardized processes to minimize production complexity.
Choosing between rigid or flexible PCBs depending on batch size and product design (flex PCBs are suitable for irregular shapes but are more costly).
The manufacturing of IoT device PCBs is a sophisticated process that spans multiple stages, including design, substrate preparation, formação de circuito, and component assembly. Each step demands strict precision and quality control:
This stage is the origin of PCB manufacturing and directly determines the final performance. Key tasks include:
Requirement Analysis: Defining communication protocols (Por exemplo, reserving RF module interfaces for NB-IoT), power consumption targets (Por exemplo, standby current ≤10μA), and environmental parameters (Por exemplo, operating temperature range).
Projeto Esquemático: Creating circuit schematics using tools such as Altium Designer or KiCad, with component selection focused on miniaturized, low-power SMD devices.
Layout de PCB: Translating the schematic into physical layout, emphasizing RF circuit matching, integridade de energia (Pi), e integridade do sinal (E) to minimize interference and signal loss.
Design para Manufaturabilidade (DFM): Coordinating with production capabilities to ensure compliance of line width, hole spacing, and pad size with manufacturing standards, reducing costly redesigns.
The PCB substrate—copper-clad laminate (CCL)—consists of an insulating base, folha de cobre, and adhesive. Preparation steps include:
Seleção de Materiais: FR-4 for consumer IoT devices, PTFE for high-frequency communications, and PI (poliimida) for flexible devices.
Corte: CNC machines trim CCL sheets to the design size with a tolerance of ±0.1 mm.
Surface Cleaning: Removing oils and oxidation layers to enhance copper adhesion.
This step forms the conductive pathways:
Laminação: Applying photosensitive film to the substrate.
Exposição: Placing the photomask over the film and curing circuit areas with UV light.
Desenvolvimento: Washing away uncured film to expose copper to be etched.
Gravura: Immersing in acidic solution (Por exemplo, ferric chloride) to remove exposed copper.
Stripping: Removing remaining photoresist to reveal complete circuits.
Layer interconnection and component mounting require hole processing and metallization:
Perfuração: CNC drilling of through-holes, vias cegas, e vias enterradas, with minimum diameters down to 0.1 mm and positional accuracy ≤0.02 mm.
Deposição de cobre eletrolítico: Depositing a thin conductive copper layer on hole walls.
Galvanoplastia: Thickening copper layers on circuits and vias to 18–35 μm, depending on current-carrying needs.
Enhancing corrosion resistance and solderability involves:
Acabamento superficial: Concordar (excellent corrosion resistance, low contact resistance, suitable for high-frequency circuits), Sangrar (cost-effective), or ENEPIG (balanced performance and cost).
Máscara de solda: Applying solder mask ink (commonly green, but customizable), exposing pads while insulating and protecting other areas.
Serigrafia: Printing component identifiers and manufacturer markings.
Perfil: CNC milling or laser cutting to achieve the designed board shape, with deburring.
IoT PCBs demand extreme reliability:
Inspeção visual: Checking for shorts, abre, pad defects, and silkscreen clarity.
Teste elétrico: Flying probe or bed-of-nails tests for conductivity, insulation resistance, and dielectric strength.
Environmental Reliability Tests: Ciclos de alta-baixa temperatura (–40℃ to 85℃, 500 ciclos), damp heat testing (40℃, 90% RH para 1000 horas), vibration testing (10–2000Hz).
Signal Integrity Testing: Using network analyzers for high-frequency boards to ensure stable communication.
Para PCBA (Conjunto da placa de circuito impresso) produção, component mounting is added:
Colocação SMT: Mounting SMD resistors, capacitores, and ICs.
Soldagem de reflexão: Melting solder paste in a reflow oven to bond components.
Through-Hole Insertion and Solda de onda: For connectors and other through-hole parts.
Teste Final: Functional validation such as RF signal strength, sensor accuracy, and system power consumption.
As IoT evolves toward greater intelligence, connectivity, and reliability, PCB manufacturing continues to advance in three directions:
The convergence of 5G and IoT drives demand for gigabit-level data rates (Por exemplo, ≥1 Gbps in industrial IoT). Key techniques include:
Low-Dk (≤3.0), low-Df (≤0.005) substrates such as ceramic-filled PTFE.
Optimized RF impedance matching.
Embedded passive components to reduce parasitics.
Shielding structures to minimize high-frequency interference.
For wearables and unconventional sensors, flexible and rigid-flex PCBs are essential:
CPFs (polyimide-based) allow bending, dobrável, and rolling, with thicknesses below 0.1 mm.
Rigid-Flex PCBs combine the support of rigid boards with the flexibility of FPCs, ideal for complex IoT devices.
To achieve compact, multifunctional IoT devices:
PCBs HDI enable multilayer, fine-line, microvia structures, supporting integration of communication, sensing, and processing in a 5×5 cm area.
Embedded Components: Incorporating resistors, capacitores, and inductors inside PCB layers to save space.
System-in-Board Designs: Integrating sensors and antennas directly on PCBs, such as printed NFC antennas.
The long-term stability of IoT devices relies on strict quality assurance across these checkpoints:
Substrate Quality: Inspect dielectric constant, resistência ao calor, e resistência mecânica.
Circuit Precision: Ensure line width and spacing tolerances via high-precision exposure (≤±1 μm) and monitored etching.
Drilling and Copper Plating: Use CCD-guided drilling to guarantee hole accuracy and uniform copper adhesion.
Soldering Quality: Optimize reflow profiles, verify joints with AOI (Inspeção óptica automatizada).
Environmental Testing: Conduct batch aging tests to validate service lifetimes (typically 3–10 years for IoT PCBs).
IoT device PCB manufacturing is not a mere extension of traditional PCB processes but a precision-driven system guided by application requirements, empowered by technological breakthroughs, and balanced between reliability and cost. Its underlying logic can be summarized as:
requirements define characteristics, characteristics shape processes, and technology drives evolution.
