Craft requirements for server PCBA products:
1. Conduct reasonable production and testing on the craft requirements and technical indicators that the products should meet after confirmed by the customer.
2. The technical information of Pcb manufacturing products shall be provided by the customer, and the file and fixture signed and received by us shall be managed according to the confidentiality agreement, including Pcb coordinate file and electronic bom.And the data will be destroyed at the end of production.
3. Lead-free craft is adopted for production.
4. Welding spot requirements: according to the standard of the PCBA industry, SMT requires reliable welding, and there shall be no virtual welding, leakage welding (unless the lack of material special declaration and other electrical fault phenomenon occurs.
5. 100% welding reliability is required.Solder joints should be plump and round.
6. Pcba manufactured products shall be clean and tidy in appearance, and pollutants such as "flux" should be dealt with in time.
Server PCBA product performance
The power supply circuit of the server main board is one of the important parts of the main board. It is responsible for converting the 12V voltage output of the power module PSU into the appropriate voltage required by the CPU, memory, PCH, BMC and other circuits.This part of the circuit is formed by a power supply scheme composed of several different VR circuits. In this context, VR refers to the power supply circuit that can convert the 12V voltage or other voltages into the power supply required by the corresponding load, including the controller chip, Driver chip and the circuit composed of their peripheral capacitors, inductors and resistors.
Equipments used in the production process
1. equipment to open steel mesh
2. SMT mounting machine
3. Reflow welding
4. Semi-automatic printing equipment
5, X - ray
Why do customers choose us?
Answer: the original supplier of the customer is not good in quality, and the circuit board has a large scrap rate
Our company totally has 9 inspection procedures to check the quality of the circuit board.Firstly,the incoming inspection standard was tested via AQ , and then the first piece was tested before going online. After going online, every procedure will be followed by inspection such as solder paste inspection, patch inspection, post-furnace inspection, AOI full inspection, manual eye inspection and QA sampling inspection before packaging.
