YM-Lab

We provide reliability test services utilizing design and manufacturing technology of printed wiring boards and the know-how on product reliability evaluation and analysis that we have accumulated over many years. We contribute not only to printed wiring users, but also to engineers to shorten the material and process development time for printed wiring boards.

For board material manufacturers

　As a development project partner, we carefully respond to your needs.

　We offer custom-made reliability tests in accordance with the characteristics of your product material under development.

　Manufacturing is made on production lines used for various kinds and small quantities/ advanced technologies.

　A wide range of support, from reliability tests to performance tests of printed wiring boards and their materials, can be provided.

※ For researchers in charge of development of printed wiring board materials such as films, copper foils, copper clad laminates, solder resist, adhesives.

Evaluation and analysis of product reliability

　We undertake reliability tests and analysis of printed wiring boards and their materials.

　We support our customers with reliability tests of our products and analysis technology backed by specialized knowledge and experience.

　Reliability tests are conducted in accordance with IPC, JIS, JPCA, etc.
