I have boards coated with Humiseal 1B73. At a late point mfg. site we need to remove a series of 0603 resistors for optioning purposes. I have been trying to determine the fastest, easiest way to re-coat the pads after removal. Drying time of the coa

Thanks for the info Sarason. The UVCL is a Urethane. Did not want that hard of finish (for solder rework issues). We like the Acrylic as acetone will remove cured material for solder rework.

I am doing some rework to my CCA. I then need to conformal coat the board. I'm using Humiseal 1A33 GEL and my jumper wires are teflon coated. I understand the chemical interaction between the 2 products. My question is "Is this an acceptable prac

A friend in the contract coating business said: "... ask why the wire is [teflon] coated in the first place, as only the solder joints should be coated in this situation as the flexing/bending of the wires will cause the coating to crack and flake of

IPC-7721, Section 6.1, Jumper Wires, Jumper Wire Selection #5 states: "Recommended wire is solid, insulated, plated copper wire, 22 to 32 AWG with a heat resistant insulation. Wire with tin-lead plating may be restricted due to environmental laws."
