Kapton tape and thermal vias

[[email protected]]

Has anyone used Kapton tape to prevent solder bleeding through
thermal
vias during reflow? Is this feasible? Thanks!

Sure, how much paste are you applying to the thermal pad?

Don't see why it wouldn't work.
Depending on your thermal profile, you could get away with something
MUCH cheaper. We have one product that an edge connector is protected
with good 'ol blue painter's tape folded over the PCB.

Not me. I like solder in thermal vias.

Me too, but I'm bolting a heatsink under the vias...Need a flat
surface with least amount of effort.
