Laco Regular Soldering Flux 60g 22103
on 4 March 2013
Solder paste is not that common these days. It was once to be found in the tool cases of every plumber and on the shelves or in the drawers of TV service technicians workshops. But copper piping and solder jointing has given way to plastic pipes and compression-fit unions and joints. In electronics, just about every component/item of equipment is replaceable: throwaway-and-buy-new. Electronic component soldering is much less common than when I was a trainee electronics engineer, 40+ years ago.
There are relatively few manufacturers of solder flux around but LA-CO has survived. This item is the non-drip, paste flux although wet flux is/was available. A 60gm container will last quite some time and I doubt I will ever use the entire contents because my primary soldering interests involve electronic circuit repair, which uses flux-cored solder rather than flux paste. Flux paste is still mostly used on copper pipe jointing - gas and water - in conjunction with solid solder bars. I have used the LA-CO flux and it is easy to spread onto a surface with a brush/sponge/cloth. Its anti-oxidising properties ensure the hot solder runs smoothly over the surface thereby making a clean and strong joint.
I deducted 1-star for the relatively high price. Flux never used to be expensive but like soldering and solder it is less widely used by the DIY-er, although it is still widely used by industry, which use vast quantities rather than small, 60gm tubes.
