Reworking Glued Components | 9 August, 1999

Folk's,

I'm looking for some helpful suggestions for reworking wave soldered bottomside components that have been glued. I'm not a fan of the twist and break approach and as some of them either have a double dot or a slot configuration this tend's to lead to removing a chunk of resist as well. I've thought of using a hot air pencil but was wondering if anyone had any other suggestions.

Usually we just use a soldering iron and burn the glue off for double dotted areas.

After removing the component the hot air should be focused on the remaining adhesive in order to remove it with one sharp tool.

I find using the rework station preheater is effective. I don't experience any of the damage you've sited.

Does your glue vendor have similar rework instructions?
