Hi Daan, We use the Circuitworks Overcoat Pen for repair purposes but usually after the boards are soldered so I don't know how it will behave during reflow or wavesoldering. It's very easy to use you only apply what you need and you don't need to mix 2 components anymore The TDS mentions that it meets the requirements of Mil-I-46058C (I'm not familiar with this one) and IPC-A-610C and there seems to be a toll free number you can call 1-800-TECH-401 Hope this helps Happy holidays to everyone out there Hilbrand -----Oorspronkelijk bericht----- Van: d. terstegge Verzonden: donderdag 18 december 2003 17:12 Aan: [log in to unmask] Onderwerp: [TN] Solder mask for repair Hi All, The 2-component epoxy soldermask that we've always used in our assembly shop for repairs and modifications of bare boards has gone obsolete. I'm looking for recommendations on alternative materials. On the web I found the Circuitworks Overcoat Pen, which seems to me is a very easy alternative, although this pen contains a green acrylic conformal coating, and not really a solderresist. Is anyone using this pen, and is it suitable for high-reliablility (military) boards ?
