Hi. I'm new in bussines. I have a DEK screen printer and I have to choise solder paste and flux. It has to be lead-free. What do you recomand? Of course it has to be cheap and good. :)

Your best bet would be to browse through you current solder suppliers catalog and pick your alloy. Most of them have a list of alloys and their melting points as well as what form they can be supplied in.

mid chip solder balls we had that trouble for awhile we went from a 8 mil thick stencil to 6 mil stencil and did some home plate style of cut outs in the stencil for the 1206 caps and resistors it seemed to fix our mid chip solder balls

We use to use a malcom mixer but found it caused problems of solder/flux separation. This may be causing you problems. Earl Jr

Is just me, or too many "soldering issues" have been observed lately? on this forum... could be a ~90% components "backwards/compatible" in both leaded/lead free process?

I heard of a new technology from OMG that helps extract more solder from drossing, I believe. I don't know where you're located, but my OMG contact is Jim Gilbert (Jim.Gilbert@omgi.com) in case you are interested.

Some solder paste formulations can be frozen with no effect. Other formulations ... not so much. Can you compare this questionable solder paste with 'known good' paste of this part number in a structured test?

Hello Again...SMTNET....are there rules to determine which small BGA devices are Dip Fluxed or Solder pasted? What drives the decision? Obviously the device's pitch has a large bearing on this decision. Any and all comments or experiences would be ve
