Tools and Hardware Reviews of CircuitWriterTM Precision Pen silver-based 4 grams
Customer Review: Useless on small circuits
Summary: 1 Stars
I bought this to repair broken traces on a printed circuit board. The board has tiny copper traces that rather close together. Some of them are not continuous and need a conductive pen or similar to complete the connections. This pen fails at making this kind of repair. It has a tiny ball at the end that you press to allow the silver conductive fluid to flow. The problem is I could find no way to press lightly enough to allow a very thin stream of conductive fluid to flow. Instead, I get big pools of the stuff which goes all over the circuit. Fortunately, it can be cleaned up with solvent, but I don't see how anyone could draw a straight line with this pen, much less a delicate repair to a circuit.Customer Review: 3 words...Does Not Work
Summary: 1 Stars
You might as well use a piece of a plastic bag to connect points. Tried every way I could to get it to be conductive. drawing a line on a circuit board and letting it dry, drawing a line and baking it as directed to "cure it" I even tried to see if it was conductive little copper circle to little copper circle on a board with the copper on it.
It may work for itty-bitty breaks on a drefroster on your back window, but as for it being some way of conducting from point A to B forget it.
I cannot believe I wasted my money, could have bought 3 spools of 22 gauge wire for less @ Radio Shack for the price of basically nothing. Just a bag of "magic beans" when it comes to living up to description.
Customer Review: It works, but is not really a "pen"
Summary: 4 Stars
I used it to repair my rear window defroster and it worked nicely. However potential buyers must be aware that the tip of the "pen" is more like the tip of a squeeze correction fluid pen, not those of paint pens or ball pens. It means it is very hard to draw a straight, fine line using this pen, especially on the inside of a car rear window. And since the lines it draw are gray-ish white, they are very visible (and ugly) when seeing from the outside of the car. You can use some tapes to cover the surrounding area and make the result looks better, but it will be a lot more work.Customer Review: For me is a very good product, but it dries too quick.
Summary: 4 Stars
I use this for a couple of years from now. Is a good product, I often use it to revive old remotes, gamepads and cellular keypads, you can brush the old conductor finish with a mid abrasive eraser and then apply a coat of this, the contact behaves as new again. The only complain is than the ink inside the marker dries too quick in the tube, I almost lost one third of the content on every market I have, I wish I know how to dilute them without damage or loss the conductive properties, I need to run this test with various alcohols, tupertine or solvents.Customer Review: Part 1 of the circuit Track review.
Summary: 3 Stars
The purpose:
Remake a keyboard 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 thick to work well and the plastic the keyboard circuit is printed on. The trace just short circuits other traces.
Solution: Do the trace then use alcohol ,cotton and a pen to clear out the extras.
