Your process makes a bigger difference than the machine. I worked for and OEM with Panasonics. They eliminated all 5% resistors, wider tolerance capacitors, and went with as many dedicated feeders as we could. We also staged jobs. We had one runnin

The next advancement is Dynamic Changeover. The Contact Systems C5 machine is the only machine you can actually set the next job up on while another job is running. This is due to high feeder capacity and feeders that can truly be removed and repla

We are setting up a facility in China and would like to verify the resistivity reading on our Westek wash machine. The only tool we have at this time is a multimeter. The machine reads .570 Mohms and the MM reads around .25 Mohms at a probe distance

And I might suggest AOI at post print and post place to hone your process before even considering post reflow AOI. Post reflow AOI alone is iffy and an absolute chore to keep up with. But monitoring paste and placement are very easy. Establish a sta

We use a no-clean lead free paste with our manufacturing floor temp 70-75F and humidity 20%-30%. We have found that if the time from pasting a board until it goes into our reflow oven is less than 4 hours we have no problems. If it is greater than

Started measuring rework last week - on some of the boards we are looking at a shocking 20% right first time yield. The paste thing has to be fixed as it's being left more than four hours. Thanks for all the comments - Will let everyone know the re

I was wondering if anyone out there knows where I may find a video of a IP3 in motion. I am looking into the used market for IP3 and want to show management. I have asked Fuji and they have come up empty handed as they only show there latest and grea

I have a project I would like to consider a Juki machine for. I am trying to find out if a Juki 2000 series machine can pick up parts from 12mm and 16mm simultaneously with all heads for good optimisation performance? IE are the heads spacing the sam

"If they complain just tell them it�s no different than finding the stray smt components that appear from time to time and makes me wonder why no one complains about them." Because they know, even as they're vacuuming up those stray Rs and Cs, that
