With the rapid development of the times, many small partners may not know that the process of PCB circuit board production and processing is variable, and we can choose our different process requirements according to different requirements, so how to choose in circuit board production?
PCB circuit board production and processing
We all know the carrier of electronic components, there are many kinds of FR4 glass fiber materials for PCB boards (the substrate is covered with copper skin), and the fire protection level and mechanical strength are different, so we can choose to spray on the surface treatment of circuit boards. 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.
PCB circuit board production and processing
In addition to the choice of process, we also need to pay attention to some common problems that occur during the production and processing of PCB circuit boards. We can divide it into two parts to distinguish.
—、 PCB circuit board engineer docking precautions are:
1. Carefully select the number of PCB samples to effectively control costs. (Normal 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 in signal integrity layout, reduce noise and improve PCB stability.
二、PCB proofing manufacturers docking matters are:
1. Carefully check the PCB documents to avoid data problems.
2. Carry out process approval in an all-round way, and carry out process configuration with their own manufacturers. 3. Control the production quantity, reduce the cost and maintain the quality.
4. Communicate precautions with proofing customers to prevent accidents in advance.
