TAB bonding machine
« on: August 04, 2015, 10:32:21 am »
Does anyone know what kind of heating  pulse TAB bonding machines use?
If induction heating or resist or different?
Thank you

I think you've confused battery tabs with Tape Automated Bonding as commonly used for LCD controller mounting. More discussion here:

A quick look showed one brand as using a thermode, and hot air probably to keep surface temp consistent. I've seen a video showing the main heating at 200C with 2.5Mpa pressure for 25s.
