This technology can produce very fine wiring on flexible, rigid substrates or other materials, and the cost is also very competitive. Because the holes are electroplated along the wiring, what is the competitiveness of rigid-flex board products? The design of the soft and hard combination board is to meet the miniaturization needs of electronic devices. If the product is miniaturized, it can basically meet the needs of automation.
When selecting a substrate, it is determined based on the specific requirements of the board. The substrate circuit requirements here refer to the rationality of the functional board design circuit, which is also necessary for later debugging.
It is also a functional test in the later stage. In order to ensure the accuracy of the test, we have the ability to save it after the PCB circuit board design is completed. Therefore, the design and production of PCB circuit boards are very important. At the same time, it is also necessary to provide PCB circuit board design and production services after schematic design or batch production of PCBs, which is also a necessary condition before conducting experiments.
For some people, there is no distinction between good and bad for PCB circuit boards, that is, there are various design requirements, so there is no distinction between good and bad. Common ones are PCB circuit boards.
What are the common problems in the design and production of PCB circuit boards? If you are engaged in PCB circuit board production, you need to find a company that specializes in PCB circuit board production.

● Process capability and process capability. The process capability not only determines the quality level of PCBA circuit boards, but also determines the quality. Therefore, in order to ensure process capability and ensure the quality of PCB circuit boards, the following points need to be achieved.
● Process capability and process capability. The process capability mainly determines the performance and quality of PCBA circuit boards. The expression for process capability is.
The PCBA manufacturer conducts a total quality inspection before leaving the factory, mainly including quality, weldability, chemical composition, appearance inspection, etc. The main inspection contents are shown in the table below.
Solderability inspection: The main inspection contents include copper foil adhesion, roughness, physical properties, weldability inspection, etc.
Roughness inspection: The main inspection content includes the adhesion and roughness of the metal, the content of rosin flux in the metal, solubility, copper oxide content, electrode content, font, lines, etc.
● Rate analysis: The main testing content includes the adhesion and roughness of the copper foil surface, the rosin flux content, solubility, copper oxide content, electrode content, white spots, density of the metal and its alloys, binder content, binder thickness, coating thickness, microstructure, particle distribution, voids, cicada patterns, glass, mechanical properties, impact resistance, fatigue, stress relaxation, creep resistance of metal parts Conductivity, electrical performance, hardness, conductivity, breakdown voltage, electrical strength, capillary resistance to melting and soaking water, chemical contact resistance, surface resistance, top height withstand voltage, gate thickness standards, etc.
