The manufacturing and export of PCB boards to various countries around the world requires full knowledge of the documentation requirements, and even certified OEM factories (manufacturing independent/in Japan) strictly follow the IPC-62B component control requirements (agree on the latest products).
To this end, raw materials (including semi-finished products and particulate matter) for PCB and other related products should be provided to suppliers in the Hong Kong and Taiwan regions, so that they can grasp the entire material.

High value OEM certification. PCBA OEMs participating in "all" orders often need to cooperate with our company or our agent, and the order quantity must be specified when placing an order.
Before production, purchase from the factory to confirm whether the production progress, required quantity of products, procurement method, and process flow meet the requirements, in order to ensure product quality.
Before shipment, inspect whether the PCB design is complete and conduct PCBA OEM processing to verify whether the work is completed.
There are orders that independently complete production or monthly production lead time testing, and customers are notified in advance in a timely manner.
According to different manufacturing categories, PCB templates can be produced. The appearance and dimensions of PCB templates can be omitted for certain special cases of orders, and only need to be used as spare parts. Then, local spare parts can be produced.
After drawing the schematic diagram for the circuit board in the BOM table, it is necessary to start from the production of PCB templates. Devices such as SMD resistors and capacitors that require debugging can be checked for their specifications, welding reliability, and welding reliability. Place the debugged PCB board into a dedicated debugging machine and automatically complete welding according to the corresponding debugging sequence. By debugging the machine in the welding sequence and connecting the power cord, the pins of the SMD are changed to complete the welding of the circuit.
There are many different details and thoughts when experts see the physical image. However, you haven't paid much attention to this process, so you need to jot down all these details. The next step is to teach you how to review.
Have the working principles of circuit board production and design been completed? Today, we mainly focus on the design and control of the circuit board, and have done all these things well. Let's see how all the components of the circuit board are built.
For circuit boards, the layout rules of various components are too large, and static electricity and electrical breakdown are inevitable to cause static electricity and electromagnetic interference, which can bring good effects to PCB boards. If one considers a person as an experienced engineer, even if they have made a good board, they do not necessarily need experience.
How to do anti-static treatment for PCB circuit boards? So, what is the anti-static treatment method for printed circuit boards?
The wiring of anti-static wires should use a suitable and regular electrostatic grid. The grounding end of the wire should be connected across the power lines;
Resistance wires should not be placed near potentials higher than 30; Do not cooperate with other electrical equipment; The shielding wire of the wire should use printed wires. Usually, the required wiring length for circular wires should not exceed 16mm and should comply with the provisions of GB 20893.
