These human errors will cause smt processing errors
Although SMT processing is now automated, some steps still require human intervention Therefore, if human errors occur in the production and processing process, it will also affect the integrated circuit board So what human errors can cause persistent problems?
Although SMT processing is now automated, some steps still require manual intervention. In this case, if human errors occur during production and processing, they will also affect the integrated circuit board. So, what human errors can cause persistent problems?

Incorrect placement of components or unprofessional production. This kind of human error will cause more than 70% of products to have defects. There are also many wrong component placement and unprofessional production steps, including:
1. Multi density foot assembly
This component has more than 8 to 20 pins, whICh is troublesome to produce and requires patience. If the production personnel do not pay attention to the number of pins during operation, the components may be placed in the wrong position, resulting in defects in the integrated circuit board.

2. Multicircuit layer
The layman may not know that in the SMT processing process, if there are multi-layer integrated circuit boards, special attention should be paid. The processing of such integrated circuit boards is relatively complex, and it is difficult for the production personnel to distinguish the specific layers with the naked eye. Unfortunately, standardized production is rarely achieved.
3. Manual welding
Manual welding is an indispensable link in the SMT processing process, especially for some products with high requirements for integrated circuit boards, this method will inevitably be used in the processing process. If the technology in the welding process is not professional enough and the operation is irregular, it is easy to lead to insufficient solder joints, which will greatly affect the operation of the integrated circuit board and have a great adverse impact on the efficiency of subsequent products.
4. No anti-static treatment
Anti static treatment must be carried out during SMT processing. In addition to not allowing employees to carry items that generate static electricity, their clothes must also be anti-static. This is the basic requirement of SMT processing workshop and Shenzhen SMT processing factory. If the anti-static measures are not well done, it is easy to reduce the life of the integrated circuit board and affect the life of electronic products.
Although many integrated circuit board manufacturers and assemblers hope that smt processing will not cause problems, these human errors cannot be avoided 100%. They can only be requested from production specifications and minimized. In addition, in order to improve the efficiency and service life of integrated circuit boards, SMD manufacturers will also use the following methods to improve the efficiency and efficiency of SMD processing:

1. Raw material control
For the purchase, storage and production of raw materials, SMT processing manufacturers should attach great importance to all aspects of the process. In this way, it is unnecessary to worry about the impact of raw materials on product efficiency.
2. Quality control
In order to ensure the final effect of integrated circuit boards, SMT manufacturers should set up quality inspection in each production link and use these methods to improve the yield of products
