If you are not familiar with its wiring and cannot find the original program, the possibility of repairing this board is unlikely. It's strange that rigid-flex boards cannot do these things well in foreign trade. Here I have listed many 12th mini demos that are available for single sided bookings. Today I will introduce these proof of doing business. Another small demo provides actual measurements during cutting.
That is placing a layer of 024 chips on a leading board. These may not seem very mature in the subsequent practice, but they are a bit mastered later on.

There is a process called V-Sub, and after specifying this process, we write a classification code to form a complete process.
● )。 When setting up the wiring network in the process, a multimeter should be used to distinguish between empty feet and virtual feet, and to eliminate the characteristics of virtual feet and solid feet.
● 。 Remember, if resistors, capacitors, or ICs are not virtual feet, the power switch and casing should be aligned with the power supply. If they are not virtual feet, the power switch, logic board, filter board, and sealing board should be removed.
● 。 All components, interfaces, sectors, etc. on the board, with some exceptions. Look, there are also some companies' circuit boards, reset capacitors, switches, speakers, power supplies, televisions, radios, and so on. They all have circuit boards, power supplies, connectors, switches, connectors and other devices.
● 。 (1)。 Firstly, there are already installed circuit component libraries and batch production equipment on the circuit board. The circuit board is basically installed according to the designed circuit board.
But how do Shenzhen SMT processing manufacturers design 7-layer circuit boards in the following different forms?
Various types of machine circuit boards have their own characteristics. Shanxi Volkswagen enhances the quality of Henan's well-known products, provides more guaranteed services, and ensures that all problems in Henan's SMT processing plants are handled properly. The design plan of Henan's PCB circuit board manufacturers is a consistent principle.
When designing PCB, Henan PCB circuit board design company needs to have a clear idea, in order to ensure that the SMT processing plant in Henan can quickly complete PCB design work, thereby ensuring that the SMT processing plant in Henan can quickly complete customer design tasks and achieve high quality.
The design plan of Henan SMT processing plant is "feasible". Designers need to first verify various SMT design types, functions, and product structures in order to achieve a complete product structure design. After the design is completed, the product structure and all key features must be evaluated without confusion. To evaluate the product structure, the characteristics that need to be designed must be evaluated to ensure compliance with design requirements before mass design can proceed.
In order to make the design work easier to solve some possible problems, it is important to spend some time preparing some common design tables, as shape is also very important. Therefore, it is necessary to carefully analyze and decompose the appearance.
