Fellow technetters,

we are presently fighting with some ultra low-end TH only PCBs. During
waving they blister a lot. We tried many things like hotter-colder
preheating, hotter-colder solder temp, faster-slower speed. No result.

Are there any other tricks to try, or we send them back to the fab?

Thanks, Ioan
