Use Case of PCB Pins Connector

Studied Customer Requirements

Based on the customer’s requirements, our R&D engineer finalized the 7-pins structure of the precise turning part connector, and, it was made of 7 solid pins and 1 housing. The material of the solid pin was lead-free brass, its coating was Au 10U” min over 50-120U” Ni. the material of the housing was HTN, UL94 V-0. the shape of the precise PCB Pin was right angle type.

Machining Process of PCB Pins Connector:

The process of turning can be divided into four steps: turning, polishing, electroplating, and assembly.

  • First, the material is cut out of the desired shape using a CNC machine, usually leaving an error of 0.01 mm.
  • Secondly, polishing is carried out to polish the PCB pins to the required surface finish.

  • Then, the electroplating material and film thickness are selected according to their function.
  • Finally, housing is used to assemble PCB Pins into the connectors.


What are The Characteristics of Them?

Substantial reduction in the number of parts and processing of complex-shaped PCB Pins without the need for multiple parts to be used with each other. Stable processing quality and high precision,

which can adapt to the processing requirements of flying chess.High production efficiency in the case of multi-variety and small batch production. The ability to reduce production preparation, machine tool adjustment, and other processes. Processing of PCB Pins does not require mold opening, effectively reducing production costs.



Application of PCB Pins Connector

The shape of PCB Pins is complex and suitable for various high-precision equipment. For example, computers, mobile phones, electronic cigarettes, and other consumer electronics.

Electronic medical equipment and aerospace need the application of a small turned parts connector.



How to Choose The Right One?

It is important to select a qualified PCB Pin. You need to choose from the precision after processing, usually qualified turning parts error will be 0.02 mm.
