About Preform Chain Pin Terminal
Overview and features
Within the scope of basic specifications, the length and thickness of the terminal can be specified without initial cost.
We also offer options for applying various machining depending on the application.
A shape that is friendly to a workpiece that does not shave the lower hole of the printed circuit board or molded product at the pin tip when the pin terminal is inserted.
In addition, by applying star processing to the press-fitting part, the fixing force can be increased.
