Database of defects

NPL defects website

The Industry Defects Database that has been set-up by National Physical Laboratory (NPL), allowing engineers to search through a range of defects covering components, printed circuit boards and assembly problems, has now yielded its first results.

Initial results suggest that open/joint failure is the most common issue seen by the industry, but these can be the most difficult to detect in manufacture. PCB solder finish is seen as the second biggest issue, which could be due to the need to change surface coatings for lead-free assembly. The aim is to add more defects each month to complement the online submissions.

“The database will take time to populate with defects, but with world wide industry co-operation and defect types from our own research studies, the result will be a unique resource,” said Davide Di Maio of NPL.

The NPL Industry Defects Database is now available for engineers to submit defects at:
