I wouldn't mix it in a jar with new paste. But in another jar to be used on the next job, sure. I mean if your concern is contaminates, doesn't that mean its contaminated on the stencil? Unless the board is a hard one to print, or has really tiny

Hi Bill! Justin hit the nail on the head with his advice. One other thing I'd add too is that if your volume and such points to using cartridges, I found that sometimes operators can get a little wasteful. I worked for a memory company where we

| Can anybody give me the Pros and Cons of of using Cartridges over jars and/or vice-versa. Also, if using cartridges, what is the best way to keep the paste from seperating, short of buying a mixer that cost over $5000.00 | Thanks, | Bill | Bill,

Another question... I use 500gm jars of Kester 256. After a job is complete the used solder is collected and put back into the jar. Generally while a job is run, the jar and used paste could be left out/open for up to 4 hours. A piece of seran wrap i

Try buying your paste in 500g pyles cartridges .You can use these cartridges in a standard caulking gun. Also.. have your paste vendor supply you with some empty jars.(They will usually do this free of charge) Whenever you run a job, dispense paste

This is one reason why we changed package styles. Maybe consider getting a different size tube, say from 500g to 1000g or something like that. We use jars for lead paste, and tubes for lead free (different application method) If lead free comes off t

Well, you don't want your paste to spoil! It'll give it a bad aftertaste. Actually, we refrig our paste mainly cause our stock room gets rather on the toasty side. Jars left un-friged will cause the metals to sink and leave a puddle of flux on top

We are looking for some sealed (pressurized?) flux tanks with low qty. warning for use with our Tamura spray flux machines. I have heard that a company named "Binks" has made similar tanks for other companies, but when I search on the net for them I

well we can't paste the flip chip on its substrate because we are using flux...because this bare die yet...and the surface of the die flipped might be contaminated...also after chip attach and reflow the die is to be underfilled and if the die is pas

I have done this several times in order to save my butt: adding liquid flux in a jar of not so fresh paste, stirring it slow for 2-3 minutes, to make it usable. Of course, use no-clean flux for no clean paste, etc. During one production slow-down,
