Hi All, I would like to get some inputs regarding this.... I have bare PCB which were stored with kapton tape attached on the Au plated pads. These were stored for close to a year. Upon removal of kapton tape, we noticed discolorations on the edges o

Hi Dave - You are correct that I was not clear in my comments. I assumed Joris had seen the usual solder balls accompanying his blowholes. Nevertheless, Joris, my first two recommendations still stand. Increasing the dwell time of your leads in t

I never saw in any post if your machine uses the camera to find the board edge or if your machine uses the bottom front rail mounted board stop sensor. Also is this with only one particular job you run on this machine or is this happening with ALL

Thanks davef. Your comments are well taken. How about the trays transporting boards from one station to another or staging at WIP Kanban? It��s easy enough to segregate rework stations and tools. Trays are used thru out the plant without segregation

Hussman, I'm curious about the same thing. No offense to some of the people here, but this forum's getting frustrating in terms of the lack of expertise. Too many rookies from foreign countries new to SMT, some of them asking really dumb question

Yes, mostly. The computer just has a setting for which size frame it is in (66, 84 or whatever). The bearing slider is almost certainly the same, too, although the rails are a different length. As best as I can tell, my 1306/20 (which is NOT a III

You might have to replace both entire linear rails, and then realign the axes for orthogonality. It depends on whether they can come up with a rail/slider that has the same height as the existing one. Bummer that NSK has obsoleted that rail design.
