Case Studies

Industry: measurement and analysis device industry

Solution:Customer issues

The substrate used in the original products is Si (sillicon) substrate, which has problems such as high cost and sharpening ofwafer in case of damage. And the measurement points are set as the maximum, with a total of 48 points, which shows the problem of high density of measurement points.

Solution:Products or the content of solutions

Alumina substrate has been developed to replace Si substrate through the company’s proprietary ceramic substrate grinding technology.

Amount

The price should not be disclosed, but it has provided us with services at a low price.

Delivery time

Delivered on time: we are very satisfied.

After delivery:Voice of customers

Perfect after-sales service: we intend to continue to cooperate in the future.

Industry: measurement and analysis device industry

Solution:Customer issues

The standard mold manufacturing method is metal processing, but the price of the cut and molded molds is high (depending on the processing equipment), the precision is not good and the effect is poor.
As long as it takes enough time and money, a sufficient level of molds can also be produced by cutting process, but the cost is too high.

Solution:Products or the content of solutions

CITIZEN FINEDEVICE Co.,LTD. uses semiconductor process (vs machining) to provide silicon and electroplating molds.
It can also provide high-precision molds and multi-layer structure molds with high demands.

Amount

It only needs hundreds of thousands to millions of yen (tens of millions of yen for cutting process) to get the services.

Delivery time

The term of delivery is 1~2months.

After delivery:Voice of customers

Successfully purchased the products of CITIZEN FINEDEVICE Co.,LTD. at the price of less than 1/10 of molds processed by cutting.
