The reliability of various electronic devices depends on the strict inspections of semiconductors. There are fine springs made by FineParts inside the contact probes that are necessary for these inspections. The smallest springs of these probes have an outer diameter of only 0.06 mm.
Are there springs in ballpoint pens? In reality, the ball inside the tip of a gel ink ballpoint pen is supported by a specially-shaped spring, which prevents dripping of the ink while allowing the pen to write smoothly.
You could say that electronic connectors are mounted in all electronic devices. This type is often needed in large volumes in a short period of time. However, in the case of FineParts, there are no problems whatsoever.
FineParts has a tremendous amount of experience making specially shaped springs.
We can work closely together from the very first developing stage.
