Looking at the entire process from LSI test environment construction to mass production from a viewpoint of overall optimization,
Emphasis on the balance of quality, efficiency, and cost
We provide solution services.
Based on our extensive experience and accumulated technical expertise in LSI testing, we design tests from scratch and build optimal test environments with mass production in mind.
Achieving stable deployment without trouble while maximizing mass production efficiency to the extreme.
With a flexible order system and broad responsiveness, we provide short delivery times and high-quality output, supporting reduced testing costs and improved inspection quality.
We handle a wide range of tasks, including test program development, specification proposals, evaluation, quality assurance, and efficiency improvements.

Cases resolved so far
Case 1: Reducing mass production costs (shortening testing time)
| Customer's concerns | The testing phase is taking too long, which is increasing manufacturing costs. The delivery deadline is tight, and we want to increase throughput. |
|---|---|
| Solution | Optimized the test program and implemented "simultaneous measurement and multi-site" to measure multiple units concurrently. |
| Results | Reduced test time by approximately 301 TP3T. We have achieved a significant improvement in production efficiency and cost reduction simultaneously. |
Case 2: Conversion from an old tester (heterogeneous deployment)
| Customer's concerns | The tester we were using is reaching end-of-life (EOL), and our company lacks the expertise for migrating to a new tester. |
|---|---|
| Solution | We will perform program conversion to rewrite existing programs for the latest testers and proxy correlation work between testers. |
| Results | We have successfully completed a smooth transition to the latest inspection environment while maintaining our traditional quality. |
Case 3: Reduction of mass production cost (improvement of yield)
| Customer's concerns | There is a product with a low yield, but we lack the know-how and cannot address it. |
|---|---|
| Solution | Identify the cause from the perspective of the tester's specifications and program, and propose improvements. |
| Results | We significantly improved profitability by increasing the yield rate. |

If we don't list your manufacturer or model, we may still be able to help, so please contact us.
We do not possess an LSI tester.
※ We will use the customer's LSI tester for the actual unit confirmation.
We are currently working to expand the range of LSI testers we can support.
