Disadvantages of flexible circuit boards: 1. High initial cost, 2. Difficulty in repair. How to layout high-end printed circuit board assembly? 3. It is mainly used for low-cost welding. The low-cost printed circuit board is generally designed as 4 to 6 layers of plates. Although it is larger than the through hole board, it can bear more current channels than the through hole board and also needs thermal expansion! Why choose a cheap and inexpensive substrate SMT process? In all cases of insufficient welding processes, it is possible to cause problems such as deformation, deformation, and drift, which can lead to problems in the design of the circuit board. Blind holes and buried holes are designed on top of this, and the blind holes are relatively thin, which can reduce the assembly area, which is also a basic requirement.
The following process also reduces the assembly area of all projects, so if it is not solved, it is necessary to lay copper to reduce the area of the board, and the thickness is relatively small. This is also why PCBs are usually widely used, with thick copper and thin copper usually only having a thickness of 015, and the process generally needs to be controlled within 02mm.
When designing a soft and hard combination board, it is necessary to press out multiple layers of the board. Therefore, the soft and hard combination board process should be chosen as much as possible to reduce glue leakage and insufficient internal glue during pressing. When reducing the window opening line, it is also necessary to use high temperature and high pressure to make reinforcement materials. When making a layered board, it is also necessary to add glue and patches, so it is the most important process of quality, If there are defects in the design of our circuit board, such as glue leakage or insufficient glue leakage caused by board explosion, the main reason for glue leakage is the low thickness of the medium. So what issues should be paid attention to when applying glue?
Gluing is the most important process of quality. If there are defects in the structure of our circuit board, such as glue leakage or insufficient glue leakage caused by board explosion, it indicates that there is a problem with the gluing line. When gluing the line, special attention should be paid to observing whether there is a problem with the gluing line. Since the gluing line is not a pure lens, followed by glue leakage, if the parameters are related to the shape of the gluing line, So it will directly affect whether there are problems with the gluing line. So it is necessary to always pay attention to whether there are any problems with the adhesive line and ensure that there are no problems with the adhesive line, For the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the future problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise, the problems that arise The wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes problems, the wind that causes.
