What matters should be paid attention to when making PCB circuit boards

source:Industry News release time:2021-09-13 Article author:sznbone Popular:pcb

　　With the rapid development of the times, many small partners may not know that the process in the production and processing of PCB circuit boards is changeable. We can choose our different process requirements according to different requirements. Then how to choose in the production of circuit boards?

　　PCB circuit board production and processing

　　Everyone knows the carrier of electronic components. There are many kinds of FR4 glass fiber material (copper coating on the substrate) of PCB board, and the fire rating and mechanical strength are different. Then we can choose to spray the surface treatment of the circuit board. Different processes such as tin, immersion gold, and anti-oxidation (OSP). In addition, we can also choose various colors for solder mask and silk screen printing, such as green, red, blue, white, etc.! Green oil is commonly used.

　　In addition to the choice of technology, we also need to pay attention to some common problems in the production and processing of pcb circuit boards. We can be divided into two parts to distinguish.

　　1. The precautions for PCB circuit board engineers are as follows:

　　1. Choose the number of PCB proofing carefully to effectively control the cost. (Regular proofing quantity is 5-10pcs)

　　2. Specially confirm the packaging of electronic components to avoid PCB proofing failure due to packaging errors.

　　3. Carry out a comprehensive electrical inspection to improve the electrical performance of the PCB board.

　　4. Do a good job of signal integrity layout, reduce noise and improve PCB stability.

　　2. PCB proofing manufacturers’ docking intentions include:

　　1. Check the PCB documentation carefully to avoid data problems.

　　2. Complete process approval and process configuration with its own manufacturers.

　　3. Control the production quantity, reduce costs and maintain quality.

　　4. Communicate precautions with proofing customers to prevent accidents in advance.
