Hi, you want something that will not break down, and something not American then. I would look at the Fuji XP-143E (if you are not going bigger than 20mm x 20mm) or the Juki then. Also I would look at what they are predominately using in Turkey, as

IP? With a MY machine what is it you are tring to solve with an IP. If you are looking for a speed improvement and corresponding throughput the cost of running and maintaining an IP is not going to balance out. However putting a real chipshooter in f

what is your peak temp.. if you try to go too high say 225-230 deg C there is a fair chance of seeing voids.. depending on your ball size and paste volume you can get a good collapse at temps below 225deg C...

with this design you will have voids, you cannot trap the gas inside of via it has to go somewhere. These vias should be relieved from pad to prevent the scavenging of the paste during reflow. You may try a thicker stencil if you can to allow for t

If you're talking about practical application who knows? If you're talking about liability I think you're going to lose. Most of the parts that I've had to look closely at had a peak AND a "time at" maximum. If they spec. 220 as the peak and you exc

We ended up switching PCB suppliers and PCB material altogether. We built 400+ units with the new material and got zero delamination. It's still unclear what the real solution is as we introduced two changes at once. This new supplier is going to

Not really. A new Electrovert AquaStorm 100, in-line machine, is under $60K, for straight aqueous applications. The batch type from Aqueous Tech are like $35K I believe. $120K would be for a high performance in-line machine, such as the AquaStorm 200

I'm reworking lead free BGAs now, on a Conceptronics Freedom 3000. I use flux only (no-clean, Indium) all the time, with no issues. If you go to paste, you also understand that you still have to hit the same temperatures as with flux, as the solder i

I have worked with both Mirtec and Yestech and you really can't go wrong with either, they both have a good support group if you need it. by my take on the 2 is that yestech is a little less comprehensive inspection wise and a little slower than Mi
