If you use acid flux at mains voltage (as a hapless customer of mine once did) the "set" will be noisy from all the electrical arcing. Roller Tinning Flux is high activity, organic water-soluble flux for flow soldering of printed circuits boards and it has been specially developed for. Ideal for working with supply lines for drinking water, copper, fire sprinklers and hydronic heating systems. Water Soluble Paste: Cleans and fluxes simultaneously. Hot Weather Formula Paste: Ideal for areas with high temperatures. Here is a typical flux (RMA) from the same manufacturer:Īs you can see, it's a translucent gel-like material with a yellowish tint, not dissimilar to what you have (however given the reference on the can to 'torch' I would be reluctant to try yours on circuits - it may be similar but have impurities that would be electrically conductive, for example).Įdit: From the comment/ link by the flux you have is claimed to be suitable for electronics: Do not use water soluble tinning paste or normal water soluble paste on electronics. Find quality hardware products to add to your Shopping List or order. They have different characteristics, though for non critical circuits it may not matter which is used. Water Soluble Tinning Flux, Paste 30142 (8Oz.) at Bakers. Water-soluble fluxes, which may be applied by dipping or spraying, have long been used in flip-chip assembly, but their long history of utility is coming to a close as a number of factors makes the move to no-clean inevitable in the high-volume sub-130micron copper pillar era. ![]() The best soldered joints come from the best cleaning and fluxing products, as well as a careful technique. Add to Cart or Buy now with Product Details Oatey Solder Soldering is the most common method for connecting joints in copper water lines. Typical classes of fluxes are RMA (Rosin mildly activated), "no-clean" and water soluble. 83 available FREE Get it as soon as today. You can stick multimeter probes into it and see if it is conductive. What you have is flux of some unknown type (although it's specified as non-corrosive so at least it (probably) isn't the typical highly acidic plumber's flux). It looks like a grey paste and under the microscope you can easily see that it is composed of tiny balls in a matrix of flux. There is a tin-bismuth alloy for the big spenders. Most lead-free alloys are mostly tin, with a bit ofĬopper and possibly other metals mixed in. It cleans the metal surfaces and removes metal oxides that can interfere with the soldering process. Here is some Asian-origin (real) solder paste:Īs you can see, the alloy (Tin 63%/Lead 37%) is specified as well as the ball size 25-45um diameter. Flux helps create a stronger solder joint. I've seen it in China, Hong Kong and Taiwan, and this "soldering paste" is from the Philippines. Tinning Cast Copper Best Composition for Brass for Rolling and Forging. Tinning Flux : Available in both water-soluble and petroleum-based formulas, this flux is enhanced with tinning-powder particles to pre-tin piping and improve the flow of solder, while also enabling even heating of a fitting. ![]() This seems to be an Asian-English thing- calling flux "soldering paste" or even "solder paste". I claim a compound or paste of which cheese is the basis, and the admix- ture. Hot Weather Flux: Specially formulated for hot-weather climates, this flux will not separate in temperatures up to 135F.
