Rework glue
« on: November 21, 2018, 01:04:50 am »
OK years back I had a hot melt glue from Japan that used to be perfect. I can't remember it now. Is there a glue that can do following for PCB rework.

a) Safe for copper tracks and Human
b) Instant - Hot melt or other way
c) For wire tacking as well as gap filling to hold / support parts and wires.
d) Preferably see thru
e) Can be easily removed or soldering rework can be thru. The glue I had from japan could be melted with soldering iron and also I was able to re-solder wires under glue. The glue will simply remelt while I solder and go solid after I finish.

If you have any more specific details, I can look around.
Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.

The one I had long back was from japan. It was yellow translucent oval shaped with about 5mm long dia, 6 inches long flexible stick.

I know many companies like 3M etc make hotmelt for supporting heavy parts on the PCB. But these can be opaque and not suitable for rework.

The fumes from some (non-hot melt) glues can be toxic. For example, 'super glue' which is often recommended for Manhattan style prototyping, emits toxic fumes when heated- It is toxic.  It really has to be exhausted right outside, just moving it around wont do.

Not a good thing to breathe.
