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.
