FAQs

How are solder-wick and chem-wik desoldering wick products classified?

Chemtronics uses 2 types of flux: Soder-Wick and Chem-Wik lines use natural gum rosin. Per J-STD-004 Section 3.2, they are classified as ROL0. Per British Std. EN 29454-1:1993 and ISO9454-1:1990, they have a classification of 1.1.1.B. No-Clean and Lead-Free fluxes are synthetic (non-colophony)flux. Per J-STD-004 Section 3.2, they are classified as REL0. Per British Std. EN 29454-1:1993 and ISO9454-1:1990, the No-Clean and Lead-Free fluxes have a classification of 1.2.3.B.

What is desoldering wick made of?

Desoldering 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 wick and into the solder joint, resulting in faster wicking action than any other competitive brand. Minimal flux residue on the board speeds up the cleaning process or eliminates it entirely.

How do you use desoldering wick?

1. Place the wick over unwanted solder, preferably on the greatest solder build up so that it maximizes the contact of the wick to the surface area of the solder.
2. Next, place your iron tip over the wick at 45 degrees and allow heat to transfer to the pad. Molten solder will absorb into the wick.
3. Move the solder tip and wick as needed to remove all of the solder at one time. Careful not to drag the wick over the pads, which can scratch.
4. Once the wick is full of solder, you must trim the spent portion and move to a fresh wick in order to pull more solder. Remove the iron and wick simultaneously to avoid soldering the wire to the board.
