isd.jww: Comments are: * Current thinking has flux volatiles being the major contributor to voiding, not scavanging by via * I have no reason to think that 0.3mm via won't gladly accept solder. Plug them, if that's a concern. * If your concern is ina

And digging a bit further, are the opens at the device level (all the solder on PWB pad, none on device pad) or at the PWB (similar to pillow defect?) After answering that, I would start thinking about(in this order)paste print quality and consisten

Got a failure while starting up our GSM, and hoping you guys have an easy fix that we're not seeing. We're getting a Timeout waiting for nozzle changer vacuum buildup. It seems to be occurring on head 2, during nozzle change. We've reseated all of

Hi, I've got a Microline 200TF - I guess it's a 1980's machine. It's gone pop and I cant fix it without a circuit diagram (there's several pcbs in it with a variety of relays, triacs and what-not). If anybody has a circuit or any othe rinfo on it I

My machines do this kind of stuff all the time. Usually when I don't want them to! But, as long as you can control the z-height during plaacement, I don't see that it should be all that difficult to achieve....depending on package size, of course.

The machine does not move to the home position. Once we hit the "Home" button all three heads will move up to the "Home" position but then 5 to 10 seconds later the following error pops up "Error 1531 - Z Axis motor alarm" before any "xy" movement i

However the OP is talking about a machine that replaces a placement nozzle with a dispense head. This is a $20k upgrade that runs at a fraction of the speed an inline stencil printer or Mycronic dedicated dispensing machine. Essemtec offer a similar

Hello all you SMT Netters! Please see if you can help us out. We have a older MPM SPM printer in great shape but it has one problem, and it is something I remember happening before but I cannot remember what to do to fix it. It happens when the tab

Hello, so basically I've been having trouble with parts popping up as they are being inserted into the PCB. It happens at random and I've gone through multiple rebuilds and tons of adjustments and still cant get a clean run. I've tried raising the cu

From what I understand, in the PCB Info window that first pops up when you open CEditor, the number of fids is multiplied by the number of arrays. So if you have a 4-up panel and you enter No. of Arrays = 4 and No. of fids = 2, the machine will look
