Probe pin /
Checker fixture

We manufacture contact probe pins for board inspection, switch pins,and various guide pinsused around checker fixtures.
We have a wide range of services, including metal and resin cutting, assembly, inspection, and the design and development of jigs by based on micro-precision processing technology.

Our precise and accurate
processing technology

Machining technology

Micron-level dimensional control technology

By incorporating the latest Swiss-type CNC automatic lathe with skilled operators, we are able to perform ultra-fine machining with an outer diameter of less than φ0.1 millimeters. The operators themselves undertake a seamless process, from program creation to tool fabrication, enabling the high-precision machining of metals and various engineering plastics.
Assembly processing

For all custom orders,
flexibly respond,
conducting all assembly processes

We conduct assembly for small lot prototype products through manual operations, while efficiently utilizing automated assembly machines for large quantity production. This allows us to flexibly adapt to various production volumes.
Quality control

From assembly to inspection,
One-stop production

We actively introduce the latest inspection machines and measuring instruments, and conduct quality control in a high-quality environment.
By concurrently conducting inspections and assembly processes for the product, we have maintained a high yield and shortened the time until shipment.
