Bryan, Dyoungquist is correct. You should not need to mix solder paste. Overmixing solder paste can adversely affect it. Follow these guidelines and you should be fine: 1. Keep unopened containers of paste in the refrigerator. 2. Take one container

If you believe: * There is air in your paste AND * You are not whipping the air into the paste ... You should: * Return the paste to your supplier * Get it replaced * Begin qualifying a replacement supplier. One thing before you go racing off to ly

Just how cold do you store your paste? And what are your solder paste reps like? Here they fall over each other giving support for their paste. And have you seen the problem with flux separation or have you only heard about it?

How do people prepare there solder paste for screen print? We currently remove them from the fridge and mix them in a 500g solder paste tub mixer to mix the flux and paste together we waste to much paste at the moment as we only use the tub for 1

At a previous location we used the Semco cartridges. Occasionally the operator would have to scrape down the stencil and knead the paste back in. That would keep the paste on the edges from drying out. It was just standard procedure.

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
