Who Cares... Mix Away! Although you should not mix different Solder Pastes' together in a container or on a stencil (Mostly due to the flux, although solder sphere size and shape could cause an issue), mixing solder brands or chemistries on a board

Hi We have recently noticed that our lead free solder wire is being supplied with expiry dates (typically 2-3 years after manufacture). I have seen "date of manufacture" information on wire before but I was not aware that a cored solder wire could e

I have always been under the impression that you want the flux make-up of your cored wire and supplemental flux (squeeze bottle) to be as identical/compatible as possible. I was just looking over a manufacturers datasheet for a resin-based cored wir

| With current soldering of stranded wires to pcb assy's the wire tends to be very brittle and can break with very little movement of the wire. We use a low residue cored wire. Anybody with advice or who has seen a similar problem/knows how to overco

From Kester's web site: "Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of thr

Unfortunately, I don't see any image. If your part will survive 300C then even convection reflow should work. The use of paste and reflow ovens are for when you move to production quantities. It sounds like you could hand solder your prototypes (proo
