Later, when you're ready for the iron again, rather than cleaning off the tip and reapplying solder, you can apply some rosin flux directly to the connection and simply use the solder that is already on the tip. However for tasks that require leaving an iron on between multiple connections, the solder sits on the tip between tasks and the flux eventually burns off. For rework and salvage, faster and more direct heat transfer helps to get in and out without burning up the component you are pulling as well as the surrounding components this is also good for virgin work, but rosin-core solder usually does the job. Without flux (dry) the iron needs to be in contact for a much longer time the heat transfer is slower than the dissipation you end up melting wire insulation and taking an eternity to solder connections. Heat flow is especially useful when soldering small terminals with an iron instead of flame. The flux, among its other functions, allows heat to flow and solder follows suite. Additional solder is a Godsend with terminal connections, rework, salvaging components, and conserving solder when running the iron for multiple connections. Do it right and get the right stuff.įor years I've counted on the flux built into rosin-core solder, but, as my skillset improves and scope of work widens, the need has overcome the "want". The cost of rework is threefold and doesn't include the mental anguish of doubting integrity. Incorrect flux must be thoroughly cleaned, and the chance of missing some or forgetting where it was used is not worth the risk. DON'T DO IT! Unless maybe you're in a true pinch and can guarantee returning to rework the job, but, even still, it's a bad idea. Based on this ambitious behavior I would not be surprised if they are attentive to feedback.īefore knowing better, I've used water based flux on some electronic projects. The seller followed up well after I received the product and expressed sincere interest in my satisfaction. One reviewer claimed it wasn't actual rosin and I disagree, but maybe they've updated the product. Color of the flux is darker than what appears in the photo, but it could be due to the different opaque container and photo lighting. It arrived in an opaque white container instead of the translucent package in the photo.
