when we run a pilot run it usually takes a lot of time because it needs to be properly adjusted so that on production time everything could be set up easily and run smoothly. on a no feeder situation, components for the next model should be already l

James, sounds like you need one of these: Feeder Arrangement Feeder arrangement problem concerns assigning components to the feeder slots Placement Sequence Placement sequencing (or insertion order) problem concerns determining the sequence in wh

Thanks for the replies, - solder paste used ? NC ? other ? Water soluble 63/37 paste - reflow in Air or N2 ? Infrared - temp ramp up before soack (�C/second) ? Will have to check. This profile has been used on numerous gold plated boards in our

A while back we checked out all our manufacturing equipment for lead free capability, we thought our soldering irons would all be fine as they can reach temperatures well in excess of lead free alloy melting points. Last week i was speaking to someo

We have Kester 256 no-clean spec'd as an alternate paste. I bring some 256 in occasionally to make sure it still works as a backup. The last batch I brought in was bridging like crazy. Scraped it off the stencil, put our regular Alpha back down an

It looks like the 330 Convection & the GF120 ovens would really stuggle to do lead free, with 3 zones (the 330 has 3 top, 1 bottom). Can't comment on the 545 oven, you'll have to get them to run profiles with a selection of your boards & check on

Thanks for the response..... The solder is actually printed okay prior to SMT.... And after placing, found missing solders at middle terminals of 0408 resistor arrays.... Package library is checked, component spec looks fine... I am suspecting the

Hi, I looked at the pictures and it looks as if it should be a straight forward solution..but obviously not. I would focus on the stencil/print more than placement machine. The placement machine simply places the part on the board!#(just one thing
