Reliability Test

Reliability tests at inergy can be divided into two categories .Reliability is applied to qualify packages, products and also to monitor the stability of the manufacturing process. Reliability testing results are analyzed for further circuit or Package improvement.

Marking Traceability

The top of each inergy product is marked with our coding system.
The picture below shows a sample of our IC code.

It is crucial to non-conforming parts control and quality control tracking. Production history can be traced effectively and efficiently by a single IC. Smaller ICs, like SOT-2X and DFN, are marked with a serial number.

Please contact our account manager for details on our coding system.

Failure Analysis Capability

Failure analysis traces back the failure results of a device, part or component. It plays an important role in product quality. Effective improvement or preventive measures are based on accurate failure analysis results. Information collection, proper sample handling, proper analysis procedures, experience, historical database review and most importantly, logical judgment are key to accurate failure analysis.
Failure samples come from customer feedback, reliability tests, qualification failures, engineering experiments and low yield parts. The experienced lab provide tool analysis services:
MA-tek: Material Analysis Technology Inc.
This lab provide chemical analysis services like de-capsulation, lay removal, etching for sample preparation, electrical analysis, emission microscopy, liquid crystal microscopy, OBIRCH, probing, SEM, TEM inspection and FIB for circuit repair.

Green Commitment

As a responsible global citizen, inergy is committed to protecting our environment by becoming a Green supplier. We began this effort by converting our products to be Green compliant starting in September 2008 and achieving full Green conversion in January 2009.

All inergy products and materials are RoHS compliant. Our Products are also available in halogen free options upon request.
