As with any issue like this, your miileage may vary with suggestions....but, here are the items I would consider: 1. Clinch tightness. I believe IPC gives a recommendation on the amount of bend in a clinched lead; make sure you're not beyond that.

We've been running our ICOM 5000 off and on since it was new in 1996. There's not much help out there for this machine as Stoelting (who bought out Westek) no longer supports it. You might need to replace the filter, which Stoeling can provide, but

We have inline reworkers, so this time has been factored in. We currently use Siemens S25/20 machines with M1 systems. The placement machines run a little slower than the AOI at times so there is time to perform review, most of the time. It's not

Does anyone have info on the "Cycle Steel" function on the Fuji XP141 machines. I am new to the industry and have not had any luck finding information on it. I talked to Fuji and they just tell me to leave it on, it will help with placement. We hav

When we first got our XP1’s the cycle steal was on a schedule. We would have boards running good and then start placing off in the middle of a run. We finally noticed that the cycle steal had run just prior to the parts being misplaced. We have turne
