our biggest problems with these parts is them laying on their sides after placement with a certain machine that we have. make sure that you do not have a planarity issue as well menaing that the leads are indeed below the body of the component. I a

Most placement machine equipment suppliers offer software for line balancing. What's with Fuji? Fujitrax is a system developed in order to attain high levels of "progress management, quality management & traceability" over several SMT lines, throug

Yep, we did it just the way you described, I think. What we did NOT do was a block conversion. We just built it a board at a time, to see if things were accurate when we first programmed it. They weren't, so we did away with the block fids, adjusted

Karen On your missing components issue: search the fine SMTnet Archives. Missing glued components is a fairly common complaint.

I have a typical SMT line setup with three machines, two Yamaha YS24s, and one YSM20. A simple board with only three components, four placements, but a large order quantity. At the moment, the line is only using one machine to place all the parts wit

Consider: * Printing: errors [ie, insufficient, excess, skipping, etc.] paste doesn�t roll in front of squeegee, paste adheres to squeegee at the end of stroke, paste does not release. * Component placement: orientation, wrong component, missing comp

Phil, as a rule of thumb, measuring machines (such as Zeiss, View and others) should be ten times more accurate, than the placement machine, in order to provide measuring values (CPK). AOI are meant to detect missing and wrong components, but not mea
