You qualified the electronic component (capacitor, semiconductor, diode, whatever). You tested it six ways from Sunday to insure will perform in the environment of use. And everything was great ... until it wasn't. WHY?
Because unbeknownst to you, a slight change was made in the component manufacturing process. It wasn't supposed to have any impact on the device - but you are using the component at its higher limits, and this small change degraded the components performance at your critical parameters.
Sampling of Analytical Test Services
* Package Integrity Testing (Group B)
* RoHS Compliance / Prohibited Material Testing
* Destructive Physical Analysis (DPA)
* Digital X-Ray
* PIND Testing
* Seal / Hermeticity Testing
* Electrical Test
This is why Component Testing is so important. To put it simply:
Testing is knowing
Lot Sample Testing and Failure Analysis are critical aspects of any quality system, and Precision Test Solutions has an impressive resume of test expertise and independent component evaluation services on a long list of Space and Defense programs. They can test to insure that you are building quality into your manufacturing process by identifying marginal before PCBA.
Failure Analysis IAW Mil-Std-883, Method 5003
* Failure Verification
* Internal Examination
* Electrical Verification
* X-Ray Radiography
* Fine and Gross Seal Testing
* Vacuum Bake
* Cross Sectioning
* Residual Gas Analysis

Precision Test Solutions also has in-house engineering expertise for Failure Analysis, to help identify root cause of failure at the microcircuit level. This critical information is useful as part of the component qualification process and also evaluating board failures isolated to a particular component.
