I don't know if it is considered a best practice but I have used brass, stainless steel, and aluminum sheet stock to make various types of masks for heat protection during rework operations.  Typically the low static Kapton would be used to anchor the shields down where possible.

Generally this is only done if there is a heat sensitive component near the area being reworked using smt rework equipment and not for the purpose of accidental solder splashes.

When I have to perform dynamic wave rework, we typically use the Kapton to mask off/protect the surrounding area.

Subject: [TN] Best Practice Question - Rework

Folks,

I was asked this morning if anyone out there utilized any type of protective board cover while rework was being performed to their assemblies.  Their notion was that using such might prevent an accidental solder splash or ball from dropping into an area and it going undiscovered.

Does such an animal exist?

I know it would be awkward and cumbersome, and would be met with a lot of resistance from people who actually perform the operation...

Thanks for your help!

Leland
