PCBA Tech - The importance of PCBA proofing

In our daily life and work, electronic equipment and various equipment have been quietly integrated into our side. And we are increasingly inseparable from them, and they have become necessities of daily life. Such as computers, mobile phones, Ipads, etc. And the core of those is PCB.

The circuit board is PCBA after the circuit board is processed. Before the production and processing of PCB, the PCBA processing plan must be designed first. The following are the main methods of proofing

1. Subtraction method. It is mainly to use chemicals to remove the unnecessary area on the blank circuit board. PCBA design and processing is mainly to use stencil printing and then engraving for processing to remove unnecessary parts.

2. Additive method. Use ultraviolet light and photoresist, and then use electroplating to thicken the certificate circuit, add anti-etching resist or metal thin tin, and finally etch the photoresist and remove the copper foil layer under the cover.

3. Multilayer method. The accumulation method is the most common method for PCBA proofing design and processing. It is through processing from the inside to the outside, then using the subtraction or addition method, and repeating this process to make a multilayer printed circuit board. The most critical process is the build-up method.

PCBA

When the manufacturer receives an order, it will conduct proofing first. It is one of the most important links in the processing and production of the entire PCBA R&D board. What is the importance of PCB proofing to the entire production process?

1. PCBA processing manufacturers often receive urgent orders, and PCBA proofing can effectively improve productivity and production speed. No matter which type of board, it is necessary to complete the proofing before mass production, which is like making a pre-made product in advance and then modifying it into a qualified product. And then batch processing and production like this, its efficiency will naturally increase a lot.

2. PCBA proofing can also reduce production costs. Whether it is an urgent order or an ordinary order, the processing process after the PCBA proofing first is more smooth, and it can be better adjusted according to the PCBA proofing process, which effectively saves human resources and materials. resource.

3. PCBA proofing can reduce errors during processing. Of course, the fewer errors the better during the processing process, PCBA proofing can effectively reduce the error rate. Especially for urgent orders and large-volume orders for PCBA proofing, and pab proofing in small-batch orders can ensure the quality of the product.
