Is superglue on a PCB harmful in any way? | All About Circuits
21,180. Apr 18, 2021. #13. Superglue for both construction and repair on a PCB works very well. The only problem is if soldering next to it the smoke is really nasty.Probably quite toxic. So keep the hot iron away from the superglue.
hotmelt glue for PCB - All About Circuits
May 26, 2019. #6. In 40 years of putting carpentry grade hot melt glued on wiring and circuit boards I have not noticed signs of corrosion. It can be useful in damping vibration, thermally coupling components to one-another and insulating against the elements. Careful, an LED assembly that I insulated with hot melt glue saw the glue melt during ...
How to insulate a circuit board? - All About Circuits
2008年5月5日 — Exactly! If it's in a plastic box, you're done. If it's in a metal box, you use standoffs. If it's in the open air and not getting warm, hot glue or epoxy over it. If it gets too warm for that (ie. melts the glue), use standoffs and put it in a box with holes and perhaps a fan.

2020年4月9日 — A very inexpensive substitute is to rub a little baking soda on one of the parts to be joined. Add the adhesive to the other part and press together. You do not need a visible amount of baking soda residue. You are just treating the surface. So, wipe on, wipe off.

2012年2月10日 — I used some wires from motor windings, they are coated. scrape the coating and tin, also tin the traces on circuit board and solder. Apply 5v and thing powered up! now I have dangling USB port. With nothing to attach to. End up using 5min epoxy and glue the USB connector to PCB. Modify the plastic to fit the USB port.
Wire Strain Relief - All About Circuits
2011年8月4日 — Joined Apr 16, 2010. 3,944. Aug 4, 2011. #4. Standing the wires straight up (perpendicular to the PCB) and placing some hot glue around the base of each wire will provide some strain relief. The hot glue maintains some flexibility even after it cools. In most applications, wires that are subject to continual flexing are specially designed for ...
How to remove this silicone potting? | All About Circuits
2014年10月3日 — There are three ways I know of to remove silicone rubber caulk: 1) Mechanical -- just pick it off. 2) Isopropyl alcohol (99%) and light mineral spirits, 2:1 (e.g. ,VM&P Naphtha, Stoddard solvent) -- requires a lot of soaking and rubbing, but eventually the mineral solvent disrupts the bond to the substrate and it comes off.

2017年3月8日 — 1. The adhesive on most of that tape won't stand up to soldering heat, it will stop sticking. The adhesive used to make a PCB blank is heat activated and done in a press to make it bond. No where near the same. That adhesive copper is usually used as a shielding for a circuit installed in an item.
