I do not know what kind of products you assemble but don't forget about the cycle time. You probably could accomplish more and faster with a custom nozzle (solder fountain style)for a specific application than point-to-point soldering as laser. I eva

Thanks davef, but having worked in the metal industry for years, I was wondering how someone would actually use a water jet to cut PCBs? I know it can cut them, but all water jets use an abrasive in the water. So, this would seem a rather "dirty" p

I am working on a new product that has a flex circuit attached to an 8 layer motherboard. There are 25+/- connections. I am investigating hot bar soldering vs ACF (conductive film) to make the attachment. I am looking for literature/papers/experim

Hi you need to dip long enough for the temperature of the part being soldered to reach about 20 degrees above liquidus of the solder. For the small parts we dip solder we had Sn62 and SAC387 baths set to 250 degrees and this seems to work best for us

Sr.Tech, Don't know about AP25's, we have a DEK. We have problems with some large board sagging in the middle, causing the board to slip under the board stop, but our DEK has the ability to program the board stop anywhere in the Y direction, allowin

All our AP's have camera mounted board stop sensors (works like a conveyor sensor). You can also mount these sensors on or near the conveyor if you want. We do not have problems like you talk about. You should call MpM and ask them if it's possibl

I bought an ultrasonic cleaner from the states and thought it would run with the usual travel adapter. So, I have obviously run 240v through a 110v unit. Something inside went pop and it hasnt worked since. Does anyone know which component on the cir

90% of the battle with thermal profiling is your thermocouple attachment. That is Process Engineering 101. It's just like painting your house. The masking and prep work will make or break the end result. KIC did a DoE on which thermocouple attach

Chunks, We have custom nozzles here in Riyadh that are designed to solder through-hole with SMT 0805 R's and C's just 0.5mm away. ERSA charged an arm and a leg for these, so I buy them from my toolmaker, Asadulah , for half the price. They come in

Thank you PWH, All good points. I use a semi-automatic printing process not a screen printer so if more solder balls and beads are created then I would be creating more re-work and that is exactly what I do not want to do. I guess the best thing to
