[sdiy] [OT] UV solder mask vs JBWeld/Gorilla Weld

[Barry Klein]

Kapton tape doesn’t stick to itself (or anything really) very well. I need to form a firm surface as it can bend and tear.  Bending would break the jumper wires between the two pieces. Guys are complaining the green UV soldermask doesn’t harden well. If it is like the UV glued I’ve tried, it doesn’t adhere very well either.  Maybe even CA glue and baking soda could be an option…

>> Sorry for the OT post but I don’t frequent other electronics forums and am hoping some of you have experience with this.  I am repairing a torn flex circuit.  I have the hardest part done - I used wires from solder wick - twisted a couple together, applied solder paste on pads scraped clear on the broken traces, and have all jumpered across nicely.  But these wires have no strength. I have both flex pieces crazy glued to a thin metal base.  I intend to free them from it using a razor blade after I apply either uv soldermask or jbweld over the joints.  I’m afraid the JBWeld won’t adhere and afraid the UV solder mask won’t adhere or solidify.  Maybe it will harden if I use really thin coats but likely doesn’t adhere to the kapton.  Any advice?
