How to choose low-cost PCB manufacturers in China

As the basic component of the electronic information industry chain, PCB is known as the “mother of electronic products”. The printed circuit board is a bridge that carries electronic components and connects the circuit. It is widely used in the development of communication electronics, consumer electronics, computers, automotive electronics, industrial control, medical devices, national defense and aerospace. The level may reflect the speed and technical level of development of the electronic information industry in a country or region to some extent. China is the world’s largest PCB production and processing base. How to find a cheap PCB processing plant? Let’s take a look together.

What factors will affect PCB manufacturing costs?

1. The size of PCB

PCB costs vary depending on the size of the board. The larger the size of the light board, the higher the cost of nature. You can use it to calculate how much your product will cost when you expand to the standard size.

2. How many layers

We know that PCB has single-layer boards, double-layer boards, multi-layer boards, and the maximum can reach more than 100 layers. The number of PCB board layers determines how many materials are used, and the technology produced is more complex. So when you ask for a multilayer board, your manufacturer may take this into account in your offer.

3. Material selection

PCB’s substrate materials mainly include gold-plated boards, OSP boards, silver boards, chemical boards, tin, and tin spray boards. All the raw materials of each species are different, so the cost is different, and some are more expensive and some cheap. It mainly depends on what materials the customer chooses.

4. Line width line distance

The PCB line is essential because it is responsible for its power bearing capacity. However, how to arrange the relationship between lines and design and available space on PCB will affect the price. The closer route is more challenging for manufacturers, leading to higher prices for these services.

5. complexity

The farther away your PCB is from standard and traditional circuit board technology, the higher your cost. More complex configuration and design will require more time and extra steps to assemble.

Although a simple PCB may require one of each processing step, a complex PCB may require three to four additional steps, and the simple circuit board does not require these steps, such as laser punching. They may also need special personnel or equipment, which will cost more.

6. Size and quantity of the hole

Many hole-related factors will cause you to pay more for your PCB manufacturing, but hole size is the most common. Smaller holes are more challenging, and they will require more professional training and tools, leading to higher costs. When the hole reaches a specific size, a laser needs to achieve accuracy.

When you have a higher number of holes, this will spend more time with your manufacturer, leading to further increased costs. In addition, if there are several layers of material or thicker, you can expect higher costs to adapt to the necessary manufacturing time.

7. Copper thick

The thickness of copper foil is closely related to the effective use of materials. The thicker copper foil is more expensive, and it will also bring additional challenges and costs. You may need to use more pre-immersion in your processing steps to fill the copper gap. Because the thicker copper, the heavier, you may also experience higher transportation costs.

8. Surface processing

Depending on the surface finish you choose for PCBs, the cost may fluctuate. You can find standards and basic surface treatment, such as OSP and Hasl, which are more cost-effective and still provide good weldability. However, some other trims may lead to higher prices.

How to Choose a PCB Manufacturer

1. Select factors that manufacturers need to consider

♦Factory size and capabilities: Choosing a larger PCB manufacturer can ensure better production capacity and technical level;
♦Factory environment and equipment: Choose PCB manufacturers with modern equipment, neat craft workshops and a good production environment;
♦Quality management system: PCB manufacturers with complete quality management system and ISO9001 certification can ensure product quality and stability;
♦Percentage and after-sales service: Choose PCB manufacturers with low pressure on time and good after-sales service can ensure timely ordering and after-sales service quality.

2.choose the issues that manufacturers need to pay attention to

♦Understand the production process and technical level of PCB manufacturers;
♦Understand PCB manufacturers’ management system and quality control;
♦Understand the after-sales service and customer evaluation of PCB manufacturers;
♦Learn the PCB manufacturer’s service process and price level.

3. How to Choose the Right PCB Manufacturer

♦Choosing PCB manufacturers with strength and reputation can avoid quality problems and dating risks during the production process.
♦Choose PCB manufacturers with professional technology and service teams to ensure the quality of order production and after-sales service;
♦Choosing PCB manufacturers with stable supply and reasonable prices can reduce production costs and operational risks.
