The Definitive Guide to an Electronic Assembly Design Review / 20
Common Design Flaws and Recommendations
Ansys continues to remain at the foref ront of the design
for reliability sector for over twenty years. As such, we
have discovered reoccurring design flaws that impact
product reliability.
Common issues include:
Poor parts procurement
The BOM review is lacking
Unreliable derating
Poor Parts Procurement
To achieve a good parts procurement, we recommend
observation of ESD component susceptibility in the
BOM prior to procurement. This especially applies to the
active components on the BOM.
The following should be addressed during the
component procurement process:
Know the ESD rating for each part and select parts (when possible) for the best ESD rating.
Identify all ESD sensitive parts on drawings.
Mark locations of ESD sensitive parts on the board with the ESD symbol.
Be aware that the appropriate ESD rating will be driven by part location.
