Use Case of the PCB Pins

Studied Customer Requirements

Our engineer double-confirmed with the customer about complete product requirements, application, and environmental protective details, and then, we internally discussed how to effectively eliminate all potential risks of the product. it was the structure of the right-angle type. the material of the precision turning part was lead-free brass, its cost was Au 4U” min over 50-120U” Ni.

R&D of precision turning part
Precision turned part drawing

The PCB Pin was processed by high precision CNC lathe based on the customers’ actual requirements, so, its cosmetic shape was varied and very complex, such as internal and external cylindrical surfaces, internal and external conical surfaces, end faces, grooves, threads, forming surfaces, and so on.

What is the material for the PCB Pin?

Brass is the ideal material for brass precision-turned components. Brass have low weight and high strength characteristics and can be precision machined to customer specifications. It also has excellent electrical conductivity and good corrosion resistance.

Machining Process of PCB Pins:

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

  • 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.
  • Finally, the electroplating material and film thickness are selected according to their function.

Electronic medical equipment and aerospace need the application of PCB Pins.



How to Choose The Right One?

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