Points for attention in PCB sample making

PCB sample making is to determine whether the printed circuit board has problems and whether the required functions can be achieved before mass production.It is very important to avoid problems in the later stage, which will lead to scrap and increase the cost.For this reason, the FASTPCBA technician introduced the PCB sample making matters needing attention:

PCB sample making
I. notes for PCB sample making as an engineer:
1. It is necessary to select reasonable amount of sample making according to different circumstances to reduce the cost.
2. Specially confirm device packaging to avoid failure of sample making due to packaging error.
3. Conduct comprehensive electrical inspection on PCB to improve the electrical performance of PCB.
4. Complete signal integrity layout, reduce noise and improve the stability of circuit board.
2. As a manufacturer, ideas for PCB sample production are as follows:
1. Carefully check the relevant documents of PCB to avoid data problems.
2. Comprehensive process approval and process configuration with the manufacturer.
3. Conducted in-depth communication with the customer, understood the customer requirements and matters needing attention in detail, and prevented mistakes.

Iii. Notes for making PCB samples:
1. Component layout and routing
Component layout and routing have great influence on product life, stability and electromagnetic compatibility, which should be paid special attention to.It is necessary to pay attention to the placement sequence of components, usually placing the components in fixed positions related to the structure first, and placing other components from large to small.In addition, the component layout also needs to pay attention to the heat dissipation problem, the heating element should be distributed, not concentrated.
2. Perfect adjustment
After the PCB wiring is completed, the text, individual components and wiring should be adjusted and copper applied for production, debugging and maintenance.
3. Make PCB samples with simulation function
In order to ensure that PCB can be tested correctly, software can be used for simulation.In particular, high frequency digital circuit can find some problems in advance and reduce the workload of later debugging.
As for the matters needing attention in making PCB samples, I will introduce them here today. I hope it can help you.Shenzhen jingbang technology is a professional PCB manufacturer, with many years of PCB production, design, proofing experience, strong strength, product quality assurance.If you need help, please contact me by email.
