Although PCB designers can make their own panels, contract manufacturers are generally recommended to carry out this work. Manufacturers collaborate to build and design panels based on size, shape, assembly standards and expected production volumes.
Some customers have designed contour lines for Keep layer, Board layer, Top over layer and so on, and these contour lines do not coincide, which makes it difficult for pcb manufacturers to judge which contour line shall prevail.
After PCB production, SMT welding can be carried out directly, which brings great convenience to customers and saves cost. Through technology integration, quality can be improved to a greater extent, and quality problems can be eliminated in the bud.
through holes are only used to connect the wires on both sides of the circuit board, the number of holes is much less, and the diameter of holes is much smaller. This design can greatly improve the installation density of PCB components.
The components should be designed inside the PCB board. The size of the PCB board area and the way of fixing determine the size of the margin around the board. In the whole page to achieve uniform layout, consistent density. Because the wider the printed
PCB design determines the manufacturing, installation and later maintenance costs of printed boards to a certain extent. Excellent PCB routing design can often achieve a higher spread rate, reduce jumper distribution, electromagnetic interference between
PCB design should consider many factors, such as external connection layout, layout design, optimization layout of internal electronic components, etc. The function of PCB design is to standardize the design operation, improve the production efficiency an
Before PCB design, it is necessary to make preliminary preparation, then design structure, layout, wiring, wiring optimization and silk-screen placement, check network DRC and structure, and finally make the board. PCB design is a flawed art, there is no
In order to improve the technical performance of the printed circuit board, we must first improve the performance of the printed circuit substrate board, and ensure the demand for high density and fine wire, copper foil, laminated insulating dielectric sh
There are three ways to learn PCB well: understand the working principle of components, learn the theoretical basis, and make more boards by hand
How to choose PCBA factory to avoid pits :1, look at the professional PCBA processing plant, PCBA processing is different from the traditional SMT patch and DIP plug-in,2, look at the service awareness of PCBA processing plant, the docking staff of PCBA p
Metal core board PCBS are not very common in consumer products, and DFM differs little from standard PCBS in other aspects of metal core board PCB design.
