CAIG LABORATORIESCircuitSealer Precision Pen acrylic-based 6 mL

Giving it 4 stars because I didn't use it. Thought I was buying the CONDUCTIVE type pen. So just a warning this is NOT a conductive pen.

The purpose:Remake a keyboard short circuited and exploded Printed circuit.Result : I'm typing on it.Problem: After taking all the precautions indicated on the Writer and the sealer I ended up developing my own method and redoing the tracks up to 5 times to get it right.Root Cause: The pin tip are still too think. The trace just short circuits.Solution: Do the trace then use alcohol ,cotton and a pen to clear out the extras.

I was very hesitant of buying this. I had a printed circuit board on the back of an instrument cluster that had several breaks and corrosion spots. A replacement wasn't available so fixing was a necessity. Cleaned the traces back to a good spot and redraw the traces. You have to wait for it to dry before being able to test for continuity. Very happy customer here

It wouldn't work as the window curve over, at the top. Will have to buy a new one.

It has a sharp pointed plastic tip that you push down on. If you are using it for the conductive ink/paint. it may scratch it off.

working good, the precision is medium but is ok, good but is not perfect, if had more precision can be better

This is a great sealer but I thought sure I ordered the breadboard making pen, I needed them both and it does a great job so if you repair or make your own boards and need to seal them for protection you can't go wrong with this sealer.

it works very well. i am very pleased.
