do you not have a problem with flux seperating from when it was chilled? due to our high mix low volume we really cant afford to have solder paste waiting for an hour or so till its ready before we can build

Sorry i wasnt very clear we already have a Malcolm sps-1 for our tubs but to move over to cartridges we need a machine to do that none of those machines are capable of mixing a 6 oz cartridge

So true, We had paste flux supplied to us from Alpha metals. It was the same as used in the solder paste. The major problem we noted was the in ability to control the ratio of paste to flux resulting in lots of voids. When we mixed enough to get the
