PCBA Tech - These human errors will cause smt processing errors

Although smt processing has been automated now, some steps still require human intervention. Therefore, if human error occurs in the production and processing process, it will also have an impact on the integrated circuit board. So, what kind of human error can cause constant problems?

Incorrect placement of components or unprofessional production. This kind of human error can cause defects in more than 70% of products. There are also many incorrect placement of components and unprofessional production steps, including the following:

1. Multi-dense foot components

This kind of component has more than eight to twenty pins, which is troublesome to produce and requires patience. If the production staff does not pay attention to the number of pins during the operation, the components may be placed in the wrong position, resulting in defects in the integrated circuit board.

2. Multiple circuit layers

The layman may not know that during SMT processing, if there are many layers of integrated circuit boards, special attention is needed. The processing of this type of integrated circuit board is relatively complicated, and it is difficult for the production personnel to distinguish the specific number of layers with the naked eye, so standardized production is rarely achieved.

3. Manual welding

Manual soldering is an indispensable link in the smt processing process, especially for some products with higher requirements for integrated circuit boards, this method will inevitably be used in the processing process. If the technique is not professional enough and the operation is not formal during the soldering process, it is easy to cause the solder joints to appear insufficient, which will greatly affect the operation of the integrated circuit board and have a great adverse effect on the performance of the later product.

4. Failure to do anti-static treatment

In the process of smt processing, anti-static treatment must be done. In addition to not allowing employees to carry static electricity-generating items, their clothes must also be anti-static. This is the basic requirement of the smt processing workshop and also the basic requirement of the Shenzhen smt processing factory. If the anti-static measures are not done well, it is easy to cause the life of the integrated circuit board to be reduced and affect the service life of electronic products.

Although many integrated circuit board manufacturers and assemblers hope that there will be no problems with smt processing, these human errors cannot be avoided 100%. They can only be requested from the production specifications and minimized. In addition, in order to improve the performance and service life of integrated circuit boards, smt processing manufacturers will also use the following methods to improve smt processing efficiency and performance:

1. Raw material control

For the purchase, storage and production of raw materials, smt processing manufacturers should pay great attention to every aspect of the process. In this way, there is no need to worry about the impact of raw materials on product performance.

2. Quality control

In order to ensure the final effect of the integrated circuit board, SMT manufacturers should set up quality inspections in each production link, and use these methods to improve the good rate of products.
