Are Tri-V cleaners good replacements for n-propyl bromide (nPB)?
Yes, Tri-V high performance solvent cleaners are nonflammable, powerful cleaners like nPB, safer than nPB, and are also economically priced.

n-Propyl Bromide (nPB) Determined Unacceptable Risk by EPA for Vapor Degreasing & Aerosols
The US Environmental Protection Agency (EPA) has determined that n-propyl bromide (aka. nPB, 1-Bromopropane, 1-BP, CAS 106-94-5) “presents an unreasonable risk for 16 conditions of use” in an August, 2020 report. “Nontechnical...

How do you prevent the valve from clogging up when using aerosol conformal coating?
I suggest you get into the habit of clearing the valve after every use. You turn the can upside-down and spray until it only sprays propellant. If you don’t do that, you run the risk of dried coating building up in the valve or actuator...

What is desoldering wick made of?
Desoldering braid (wick) is made of fine strands of ultra-pure copper woven and coated with flux. Its geometrically precise weave design allows for maximum capillary action and solder capacity. Soder-wick optimizes heat transfer through the...

How do you use a desoldering wick?
Place the braid over unwanted solder, preferably on the greatest solder build up so that it maximizes the contact of the braid to the surface area of the solder. Next, place your iron tip over the wick at 45 degrees and allow heat to transfer...

Does solder wick expire?
Yes. As the copper is exposed to the open air, oxygen and moisture in the air interacts and oxidizes the copper. This oxidation is most apparent by the color of the wick. The brighter the copper, the fresher the wick. Oxidized copper will darken...

Are you supposed to cut off the solder wick before or after you use it?
The temptation is to desolder an area and keep moving up the spool of braid. However, it’s best to work towards the end of the braid to isolate the heat. Once the desoldering braid is brought up to soldering temperature, the flux has been...

What is a solder wick?
Desoldering braid or “wick” is a pre-fluxed copper braid that is used to remove solder, which allows components to be replaced and excess solder (e.g. bridging) to be removed. The soldering iron is applied to the wick as it sits...
