One of the greatest advantages of this product is the built-in SW26 flux core. This flux is based on rosin and organic activators, which makes the soldering process run smoothly, and the tin spreads perfectly over the joined surfaces, eliminating the risk of creating so-called cold joints. The wire diameter of 1.5 mm makes it exceptionally versatile – it is perfectly suited for soldering wires, connectors, and larger through-hole components on printed circuit boards (PCB). Thanks to the large 250g mass on a single spool, the product is very efficient and lasts for a long time of intensive work.
Using Cynel Unipress wire guarantees high thermal and electrical conductivity of connections, which directly affects the durability and reliability of the repaired equipment. This binder is resistant to oxidation during the soldering process, which allows for obtaining shiny and aesthetic solder joints. Flux residues after finishing work are non-corrosive, however, if necessary, they can be easily removed using isopropyl alcohol. By choosing this product, you are investing in a proven solution used by professionals in the radio and television industry, which gives you the certainty that every weld made will meet the highest technical standards.
