Are they talking about size or qty ? Accountants sometimes refer to shrinkage when they are talking about inventory quantity discrepancies. Just asking, Don't know of a std that refers to this. Dave

There is no standard. Component loss is a function of many factors, including: * Component type. * Component packaging. * Machine capabilities. * Feeder maintenance. Search the fine SMTnet Archives on attrit* for some guidelines.

Dear all: For PBGA replacement by a hot air BGA rework station, do I have to follow the same temperature profile as the first original one in the reflow oven? Note that in the rework process I use only Flux paste (no solder paste is used). Hany

Your PBGA rework temperature profile should be similar to the same temperature profile as the first original one in the reflow oven. Searching the fine SMTnet Archives gives almost 500 postings on BGA and rework*.

Well assuming that the parts are genuinely damaged when rejected and you want to rework them to reduce scrap,you could use a shadow graph and get the mechanical spec on clear film.Then rework accordingly you should be able to rework most leads.

Stephano: Since you have not thought through this, it indicates that your discrepancy reporting and resolution process probably requires critical review. Consider highlighting this issue to your quality assurance staff.
