Hi All, In IPC-A-610 there is a definition for what constitutes "Entrapped/encapsulated/attached" on page 5-14 in the note. It says that it means that the ball will not be dislodged in the normal service environment of the product. Jim Jenkins

Stick a label on the package with the initial opening time and date & the use by time, then check before using again. Use the disposable indicator cards - if the are attached top the waffle packs they are getting the same exposure. Get your supplie

I agree with the local fids concept. This is usually a problem since the flex will most likely not have fids. However if your components are 50-mil pitch and 1206 or larger, you could use tooling holes to align the flex circuits when they are attach
