Highlights of the Survey:


- All manufacturing areas are environmentally controlled depending on the processes performed.


- Defective or non-conforming materials are identified and properly segregated from acceptable 



- Up to date calibrated machinery is being utilized for fabrication.


- Statistical Process Controls are being utilized in all process applications. SPC data is collected  

  on a daily basis for trend analysis.


- Experienced and trained personnel performing the fabrication processes. Concurrent training

   provided onsite, and supplemented by local instructors.


- Acceptable workmanship standard for soldering, bonding, and epoxy attach processes. Internal  

   criteria is equivalent to NASA workmanship process stds.


- Daily Destructive testing is performed for the wire bond automated equipment.


- Reliability assurance capabilities include, but are not limited to: Worst case analysis, FMEA, 

   and DPA.


- Monthly process reviews held to maintain fabrication acceptability.






- Internal Conformal Coating process procedure is very basic and undefined. No thickness or   

   inspection criteria documented for this application process.


-  The Teledyne (GLAST) Assembly process specification, does not specify applicable sections    

    in the reference documents.


-  No Receiving Inspection being performed for drop shipped parts. Identification and damage

   are the only incoming inspections being performed.

Summary / Recommendations:


Teledyne Microelectronic Technologies has demonstrated their ability to fabricate a flight worthy product through their process and quality controls. Their fabrication experience varies from hybrid to printed and multi-layer assemblies. The only areas needing attention are the conformal coating process and receiving inspection of drop shipped parts. SLAC Engineering is currently working with Teledyne engineering to integrate the instruction and criteria into the GLAST engineering documentation for the conformal coating process. SLAC Quality Management is implementing a plan, to retroactively perform receiving inspection on all previous and future drop shipped parts.
