Dear Chris Thank you so much for the prompt reply and it really helps. Do you have any SMT experience for rig-flex boards? Can you share with me about the differences with that of rigid boards? Is there any special precaution needed? When you were d

Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have

We are currently looking into purchasing either a Fuji NP or Universal Flex jet machine. Does anybody have any feedback from running these machines in a production environment? I now that a limited number of each machine has been released so far.

Hi Christina, What would you be basing the yields off of? Is it solder defect, component placement, etc....? I have worked for a flex house for quite a few years. You are right. The Polyimide is very dimentionally unstable. (even more so on humid da

Mike- This is sort of how it goes with Zevatech/Juki. 710-chipshooter, 720-Flex mounter 730-chipshooter, 740- Flex mounter 750- chipshooter, 760- Flex mounter (at about this time, Juki took over). So yes....the 730 is compatable with either the 74

I do a lot of thermal cycle testing of new components for my company and often when I lay out a test board I'm trying to simulate 4 or 6 layer boards but I don't need them for routing so I just use a solid fill of a cross-hatch pattern. I've done it

Francisco, You need to be concerned about "lead-free" BGAs. The SAC balls will not reflow at at standard tin-lead process temps. I have seen many examples where this has been a very big problem. In once case the BGAs just poped-off when the board was

Quick Change Tooling is one advantage for DEK when comparing the MPM UP2000. DEK has Form Flex. Good system, but I've heard concerns about long term dependabilty. All support tooling options offered on the UP2000 takes a bit of time to set up. So, If

Check to see if there's a loose cable, or something, that's randomly setting off the light curtain. We occasionally have that problem with some of our flex or 12/16 mags in our TP9, where the tape take up clip is loose (nothing in that feeder) and i

Thanks Sr. If you have zero tolerance for simul pick up in your component files then you will not have simul pick up due to variances in your head offsets. So you are saying that on your Juki you run a tolerance for 0201? All other head positions at
