Heat seal connections

[Jeff_Birt]

In the past I have covered the flex cable with a layer of Kapton tape and then used a wide chisel tip on my iron. The iron is of course turned down to a suitable temperature. You do need to press down a bit, you need combination of heat and pressure, and wipe in the direction of the pad/trace.

Several months ago, I bought one of these special heat seal iron tips suggested by a friend, but have not had a need to try and use it yet: https://www.aliexpress.us/item/2251832834432706.html
