If I encounter failures when using or testing Calterah chips, who can I reach for assistance?

If you encounter a failure or a defective part, you can directly contact your sales, FAE or CQE for assistance.

After receiving the feedback on failures or a defective part, Calterah will conduct non-destructive analysis on the chip first, such as balling, ATE, appearance inspection, X-ray, ultrasonic scanning, etc. If further analysis is needed, Calterah will carry out destructive analysis on the chip, such as opening the cover, taking the die, locating the failure, de-layering, etc., until the root cause of failure is determined.

To find the causes of failures, Calterah uses the analysis methods of Is-Is-Not, 5W2H, etc. In cause analysis, Calterah uses the analytical methods of Fishbone Diagram, Fault Tree Analysis (FTA), and 5 Whys to verify the problems found and then formulate and implement effective improvement measures. In the end, Calterah will offer customers 8D reports as feedback.
