I am wondering if the failurs that people see are discovered right away or when the units are out in the field. Reason I ask this follow up question is the units that are having problems are all returns from our customers. Is there a way to check for

I am new to the company but the story sounds the same. We have a new board coming in (with CREE LEDS) and I wanted to get in front of it, and found these nozzles. We are going to try them out as soon as we get the spending O.K. They are designed for

We just switched to using a paint marker to tag our xouts, and it fixed alot of the problems with using labels(causes over pasting) and using whiteout pens. what were using is the same brand we use in our inspection dept for tagging issues, UniPos

Mikej, I'm only running a single image, just want to correct for the slight variations in how the board seats in the transport. It's not more than a few mils off, but enough to cause an issue on fine pitch parts. I don't have any image fiducial

I'm assuming it's your x wagon tranducers that are out of synch. So the first place to start is look at your couplings on both x motors and make sure one of them isn't broken or starting to break. After that i would try swapping out your x board with

We are having a lot of tomb stoning with this no clean solder paste. It's limited to larger, complex boards, affecting 0603 ferrite beads, capacitors and SOT23s. It was suggested that paste removed from a stencil should not be put back in it's origin

In my experience Both Dek and speeline machines are good used. personally I think speedline seem to hold up better when PMs have been ignored though. Also make sure you can get a third party board support system into it like a gridlock or Vacunest

In those cases where we have a 3.2mm thick, 16-layer board with several GND layers, do we still need ground connection to each and every layer (with thermal relief) or, skip part of the ground patterns? Will it help soldeing rising. I can't reach mor

I can't see the fill as they are underneath the connector. As far as the direction 95% seem to be perpendicular to the wave with the occasional parallel and some all the way around(not many). I have tried altering the speed, I've played with the fl

good question Reese In addition what type of flux do you use? after seeing the board am pretty sure it's a no-clean but is the flux water based (VOC free) or solvent (alcohol based) Maybe one more question what brand and type of wave machine you use?
