It's just that the products are different, and the circuit boards are also different, so adjust according to the actual situation. Investigation and Reflection on the Development of printed circuit board assembly Industry.
Macroscopic transmission and vigorous development have led to increasingly high overall technical requirements for electronic products, with smaller components, especially high-density interconnecting HDI and high-density connecting devices. Therefore, it is required that the volume of components become smaller and smaller, making it easier to implement rigid flexible interleaved circuits.

As the frequency of device operation increases, the effectiveness requirements for packaging and testing continue to increase in new module interfaces, such as interface density, SOP, and QFP of previous devices.
I understand that 16 packaging and engineering development modules have been provided to some HIS device and system engineers before.
