The previous article has given you a brief description of the cover PAD design, exposed PAD design and other two common designs. Now, let’s talk about the other two designs – half cover and half exposed design, and other large design. Half cover and half exposed design. As the name implies, there is a part […]
Design for manufacturability ,We consider the manufacturability of our products from the beginning of design, improve the straight-through rate and reliability of our products, and make them easier to manufacture while reducing manufacturing costs. Design for manufacturability is based on the idea of parallel design, in the design phase of the product to consider the […]
Both rigid and flexible printed circuit boards (PCBs) are used to connect electronic components in a variety of consumer and non-consumer devices. As the name implies, rigid PCBs are circuit boards built on a rigid base layer that cannot be bent, while flexible PCBs (also known as flex circuits) are built on a flexible […]
PCB manufacturability design and case study of the character, shape, assembly board (graphic combination, recommended) PCB design is complicated, and various unexpected factors can affect the overall solution. In order to produce high-quality PCB boards on time, without increasing design time and costly rework, design and circuit integrity issues must be identified early in the […]
We often meet various diffrent questions in design pcb, for instance, impedance matching or EMI rules. I’ve sorted some questions and answer about High-speed PCB, hope has some benefit to everybody. 1. How to calculate impedance matching issue at design high-speed PCB schematic layout? Impedance matching is among the vital factors in designing high-speed PCB […]
1.Laminate cutting (CUT) Cutting is the process of cutting raw CCL(Copper-clad laminate) into boards that can be made on the production line First, let’s explain a few concepts. a) UNIT: Refers to the PCB design engineers to design the unit graphics. b) SET: Refers to the engineer to improve production efficiency, facilitate production and other […]
From PCB design to all the components soldered to complete a high-quality circuit board, requires PCB engineers, soldering technology, soldering workers and many other aspects of control. Generally, people who are engaged in circuit design rarely solder circuit boards themselves, so they do not have extensive soldering experience. And the workers in the soldering factory […]
Many PCB manufacturers have huge competition with each other nowadays so parts suppliers insist on costs down under strong survival pressure. The situation could lead to a bad result, that is some suppliers tilt to purchase more cheap materials to replace good quality materials. Cheap means bad quality and lower cost, but hidden huge hazards […]
In the wave soldering process of PCB Assembly, although the residual tin bead on the circuit board is not the most serious disadvantage, it is a time bomb with the most unstable quality. The generation of tin beads should be generated when the printed circuit board leaves the liquid solder surface. Although there are many […]
1. What is PCB warpage? and, What is warpage standard? Board warped refers to the bending of a flat PCB board, also known as warpage. Serious warpage is a bit like an arch. PCB isn’t 100% flated at the actual manufacturing. We can judge the warpage degree of PCB by “warpage degree”. According to IPS […]
