The circuit board designed by the design engineer needs to be manufactured by the circuit board manufacturer, and then various components are welded after the circuit board is proofed, and finally assembled into the product shell to form a complete electronic product . Therefore, circuit board proofing is an important link in the production process of electronic products. So what should be paid attention to in order to obtain a good quality circuit board proofing.
What are the matters needing attention for circuit board proofing?
1. Pay attention to control the number of PCB proofing
Because circuit board proofing is usually produced in small batches, the start-up cost for circuit board proofing manufacturers is relatively high, which will increase the cost of enterprise proofing. In order to better control cost investment, enterprises are conducting circuit board proofing. It is necessary to do the calculation before, count the samples that need to be assembled and the spare parts, and control the number of samples.
2. Pay attention to the approval of the PCB proofing process
Since circuit board proofing can also be carried out with a variety of different processes, in addition to looking for a professional circuit board proofing manufacturer, it is also necessary to pay special attention to the approval of the proofing process used by the PCB manufacturer to ensure that the process adopted by the manufacturer The configuration can meet the company's circuit board design and manufacturing requirements. In addition, it must be able to perform flying probe tests after proofing.
3. Pay attention to the layout of the PCB proofing signal
Whether the signal layout of the proofing board is complete and reasonable will affect the quality of the entire PCB proofing. Therefore, when making circuit board proofing, the enterprise should also pay attention to the signal layout of the proofing to ensure completeness and reasonableness. It should also check the electrical aspects comprehensively, so as to be more accurate. It can improve the electrical performance and stability of the circuit board and reduce noise at the same time.
The above are a few things that need to be paid attention to when proofing circuit boards. In addition, enterprises should also pay attention to good communication with designers and operators of proofing manufacturers when proofing circuit boards, and carefully deliver proofing materials. Check the relevant documents and the packaging of components. Don't fail the proofing or the effect is not good because of negligence in some small things.
