Testing
Swindon Silicon Systems Limited has two production test facilities, one for low volume production and a second for high volume production, and a fully equipped device evaluation and characterisation laboratory.
SSSL's array of ATE Test Equipment includes:
The Automotive market is SSSL's largest operating arena and as such we have to be able to provide the correct level of screeing in accordance with AEC - Q100.
Below is a list of the AEC-Q100 requirements and how SSSL manages the operation.
| AEC - Q100-001 | Wire Bond Shear Test | Out Source |
| AEC - Q100-002 | HBM ESD Test | Out Source |
| AEC - Q100-003 | MM ESD Test | Out Source |
| AEC - Q100-004 | IC Latch Up | SSSL |
| AEC - Q100-005 | Non Volatile Memory | SSSL |
| AEC - Q100-006 | Electro Thermal GL Test | SSSL |
| AEC - Q100-007 | Fault Simulation + Test Grading | SSSL |
| AEC - Q100-008 | ELFR | SSSL |
| AEC - Q100-009 | Electrical Distribution Assessment | SSSL |
| AEC - Q100-010 | Solder Ball Shear Test | Out Source |
| AEC - Q100-011 | CDM ESD | Out Source |
SSSL has capacity for both burn in and cold temperature testing.
Our Burn in capacity includes the use of 3 ovens, which are mainly used for life test, and our cold temperature testing includes our handlers as above plus 3 thermostreams.
Test Philosophy
The SSSL test philosophy is purely dependant upon yield and volume and is on a case by case basis depending upon what makes commercial sense for both the customer and SSSL.
High volume high yielding parts are assembled without probe and lower yielding parts are either sample probed or fully probed.
All Production devices are 100% final tested.
SSSL conducts Hot/cold batch testing on first production quantities and thereafter ambient testing only is prefered for cost reasons but is wholly dependent upon our customer's requirements.
