PCB Blog - What processing rules need to be followed during PCBA processing

Precision machining can easily cause damage to components due to improper operation or other reasons. Therefore, for the PCBA processing link and operation process, what principles should be followed in the PCBA processing process?

It is reported that improper operation will lead to the damage of components and PCBA, resulting in cracking, breaking, open circuit and bending fracture of components and connectors. Therefore, in order to avoid these situations, it is necessary to strictly abide by the PCBA processing rules, especially Are the following points, both basic and important?

1. Keep the working environment clean

The working environment consists of two parts, one is the workshop area and the other is the workbench. It must be clean and tidy, and no food, beverages, etc. should appear, and ashtrays, cigarettes and other items should not be placed at the same time. Smoking is prohibited.

2. Reduce PCBA processing steps

The more complicated the PCBA processing steps are, the better. On the contrary, the PCBA processing manufacturers emphasize that the fewer the better, the PCBA processing steps can be reduced to the limit, which can reduce the probability of danger. At the same time, when operating, be sure to cooperate with gloves, don't be too troublesome, and get started directly, it is easy to hurt your hands and cause work injuries. In addition, gloves should be changed frequently so as not to affect the operation.

3. Do not operate with bare hands

Grease in human hands will reduce the solderability of components. Therefore, it cannot be directly operated with bare hands or fingers to avoid the reduction of solderability.

Four, can not use hand cream, detergent containing silicone resin

Both of these things can lead to reduced solderability and failure of the coating to bond, so, unusable, are basic guidelines for shop operations that any employee should follow.

5. Do not superimpose PCBA

During the operation, some novice employees will stack the PCBA boards together because of unskilled operation, which is prone to physical damage and is strictly prohibited. The correct thing to do is to put it on a specially configured dedicated bay.

6. Select appropriate signs for sensitive components

Among the PCBA components, some are more sensitive, such as EOS/ESD, etc. These are very sensitive components, and appropriate signs must be selected. In addition, during operation, static electricity is also controlled.

The above six points are the rules that must be followed in the PCBA processing process. It looks troublesome, but in fact, it is the basic requirement to ensure a smooth workflow.
