The holes on the circuit board which need to be covered are very small and it is more time consuming to cut to size and place with kapton tape. Thanks for the feedback.

Does anyone know of a company that cuts kapton masking to desired shape per Gerber Data for conformal coat masking applications? (Preferably Pacific Northwest Region).

As Mark states, we have also used tape to cover sharpie notes and part numbers. Works well. We use kapton tape.

I don't understand the issue with Kapton as long as you put a slight load on the tc so it can't lift. It takes a little more tape but it seems to work. Not as well as HT solder but much more convenient.

Yep, we either use kapton tape or mask now depending on the application. It would be nice to be able to do it on a machine but the Hover-Davis label feeders are very expensive. May not be worth the cost for the volumes we run.

If you are using SMT machine for component placement you may check your nozzle where in some cases solder paste stuck to it and during placement will easily get into gold pad area. otherwise you have use kapton tape in order not to expose those pads.

They do make smt leds that mount topside over a hole and shine down ya know. Then just kapton tape the holes and wave it.

If you're too lazy to search, the quick answer I can give you: ALUMINUM TAPE! Try it. DoE's have proven, that it's the 2nd best method for T/C attachment. The best is obviously hi-temp solder.

Shorting your thermocouple wires is not a good thing. Be careful where you contact the wires with your tape.

Thanks - We ended up using a kapton stencil mainly due to the fact that we couldn't get time on the SMT lines. It worked great, protected the vias and the BGA functions fine.
