I thought you said that the parts that weren't wetting in reflow were the parts with epoxy. The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in reflow? Conversely, if they don't wet in wave,

A recent thread regarding the ACE KISS equipment has me wondering if anyone is happy with their choice in selective equipment. I don't see much mentioned about Pillarhouse, Juki, ERSA and some of the others. We're currently debating whether to inve

Thanks, rywman. I do have a solder sample along with dummy BGA's so we should have what we need. This BGA is actually 1152 pins (I didn't have that right in my original post). The bad part is that we are building only one board only and the actua

CC True enough, indisputable and factual...my whole point was that there was NO communication from the company(s) or the peddlers on the subject, causing an unimaginable number of wave operators, engineers, production managers and CUSTOMERS to pull o

Whoa dude - slow down- maybe great beer money but if you don't have good environmental and ESD controls in your shed, all your suds slush fund will evaporate in RMA's costs. A small pick and place (table top) would do. A manual screen printer would h

Dear Steve. We are EMS company and we are getting wide range of components from our customers. Some of them came in trays, that can withstand up to 75 degree maximum. If someone will not pay attention to this the tray get damaged (if there is some Q

Innovative Drying Co., considered this possibility early in our experiments. The rate of chamber pump-down is not a consideration. However, the selection of the vacuum pump is critical. Avoid oil-sealed pumps at all costs. A poorly maintained oil-tra

Good to know there are a few smart people left in this industry like Darby. I love how everyone assumes the original poster was only talking solder paste. We use screen printers for five different materials. Some of which we triple print by design

Davef, thnx for your reply. Sorry, forgot to clarify "our normal soldering process". We use standard Sn/Pb & SAC305 for our non RoHS & RoHS requirements. We only have a "No Clean" process, no aqueous flux is used. Hence our flux will be mild. As susp
