Manufacturing Technology for Sewing Needles

A sewing needle has such a simple shape, and its manufacturing method is also simple, just "Cutting, Grinding and Polishing.” However, it is still manufactured through more than 30 processes at present. Doing strict quality control thoroughly in each production process, we have been exporting the highest quality products to more than 40 countries over many years.

Making use of traditional manufacturing technologies for needles we have accumulated over many years, we always try to innovate and pursue new technologies to develop new needle products. Among new technologies we developed, the most innovative & leading-edge one is Ultra-fine Wire Processing Technology. One of the most important process of needle manufacturing is Point Grinding Process where thousands of straight-cut wires are conveyed by feed wheel, and are continuously polished by grind stones to sharpen the tips of wires and make needles' points. Having made this Point Grinding Process much evolved, we developed the high-precision Processing Technology of making ultra-fine wire into a needle shape.

 
 

High-precision Processing Technology of Making Ultra-fine Wire into a Needle Shape

High-precision Processing Technology of Making Ultra-fine Wire into a Needle Shape

Do you know how thick human hair is? It is said that thick one is 0.10mm thick, thin one is 0.06mm, and 0.08mm on average. We developed New High-precision Processing Technology to make the Wire, whose thickness is the same or thinner than human hair, into a needle shape, and utilizing this technology, we are making Probe Needles for Semiconductor Test etc. for world market at present.

There is the tool, called Probe Card, for testing semiconductors at "Wafer Test" to check quality of IC or LSI in the first process of semiconductor manufacturing. We are now mainly producing & selling Probe Needles used for Cantilever Type Probe Card and Vertical Contact Probe Card. Our probe needles made by our unique & precision production method are called "Mechanical Grinding Probe Needle,” to distinguish them from Probe Needles made by conventional method of chemical etching.

The features of our Probe Needles (Mechanical Grinding Probe Needles) are;

  • Higher quality & higher precision in taper shape & taper angle etc. compared with etching needle.
  • Even though the wire material required becomes much more thinner, high precision can be assured on our probe needles, and so we can meet future Probe Card's requirements of narrow-pitch (or high-density) & increase of number of needles.
  • Compared with etching needles, our needles are very little variation in quality, low fraction defective and have high yield ratio.
  • Thought is difficult to make high precision probe needle by chemical etching method for alloy material, we can make it with high quality & high precision against any material.
  • Our production method of Mechanical Grinding for Probe Needle is not so called "one by one" grinding.
    We put from 2,000 to 3,000 pcs. wires on feeding machine in one time for continuous automatic grinding in the same way as a sewing needle's Point Grinding Process. As a result, quality uniformity in one production lot (from 2,000 to 3,000 pcs.) is so excellent, i.e., very little variation in quality, having high quality & high precision. Mass production is, of course, possible.

We recently developed MEMS type Wire Probe of CD 0.02mm, which is about one forth of human hair thickness.
The length required as minimum is 3.5mm.
Diameter: from φ0.02mm to 0.08mm
Length: from 3.5 to 20mm
