LSI Test Solutions Business

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.

Solving LSI testing challenges with technical expertise and optimal solutions.
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)

Reduce mass production costs
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)

Conversion from an old testa
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)

Reduce mass production costs
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.
