| New developments in bulk feeding are making this process of feeding passive components more and more attractive to the PCB manufacturers, for | whom the tape feeding for a long time was the solution. The rapid growth in the number of passive compo

| I need to install some new lines for high mix low volume products in an already cramp building. Could someone share any info about the machines which give you the best bang for floor space. I need a 2 machine system for placing 0402 to fine pitch,

Davef, You have a good question. If we had perfect design engineers out there that would use the proper component spacing and not put SMT parts between and around thru-hole parts - glue and wave would work perfectly. I have done this with great su

Billy and Chris have a good point, pad size and geometry will affect proper aperture size and geometry and could result in tombstoning. Also I have seen chips which require special pastes but I have never found this to be the cause of tombstoning, in

John, we have waved 0603 packages for a long time, We have also started on 0402. Are you concerned with shorting across the component body or to other components? You should have no problems with these parts in a wave process. A couple of things

0603's and 0402's are being damaged by the water wash post reflow. PCA's are 1" X 4" and 2" X 2" approximately. We've adjusted water pressure so that the top-down is higher than the bottom up. The baskets have a .5" mesh spacing. Some baskets h

Zoinks!! Doing the homeplate design on 0402 will actually make your tombstones WORSE! Think about it. Your wetting forces are now on the ENDS of the device with no solder paste toward the middle of the device to tack the part down - a gauranteed f

| Thanks to all Earl, Mathew and David for the SMT info. I have one more question. Does anybody have a chart listing the standard, industrial spacings? Perhaps listing in each unit, say XX mils = XX Pitch. Or XX mils = XXmm or something of that n
