electrical tape for insulating chips

Recommended Posts

i was wondering, is basic electrical tape, such as the one listed below, will it be safe and provide the insulation for gpu chipsets / cpu or any other chipset that has exposed capacitors / resistors on the package so that it can protect it against any conductive thermal paste that may get smeared onto the area by accident? i noticed some electrical tapes mention up to 105 degrees celsius for operating temperatures, but some only list up to 80 degrees. i'm not sure if this is true, but doesn't the package area ( not the die ) run lower in temperature than the die? if so, i don't think they would get higher than 80 degrees celsius, but obviously, the 105 degrees celsius one is safer.

also, here is a picture below of the types of chipsets i'd use the electrical tape on ( as you can see, there is exposed metal on the package ).

No, "basic" electric tape can "resist" those tempoerature, but it will become a mess (the adhesive part).

You want so-called Kapton tape (for permanent protection).

If the issue is thermal paste smearing, put less paste ;) or use a masking with common painter/bodywork paper tape (and remove it once it's done).

thanks, the kapton tape seems to be exactly what i would need. it's surprising that from the many forum topics i came across when specifically searching for electrical tape for use on chipsets, that no one had mentioned kapton tape.
