If it has been determined that it is definitely the relays (and not some other circuit device), you'll want to get the vendor/manufacturer involved for some failure analysis. They'll cut open the components, and try to figure out what's going on in

Another interesting response! The PMTech machine looks interesting, but I doubt we will get clearance to spend this amount for a machine that doesn't get used several times daily. I wonder how much the Blundell machine is? Anyone have a costing for

Our success rates with MyData vibe feeder were always tentative. Sometimes you'd get it to go great, sometimes, not so much. MyData allows you to control frequency and amplitude on the vibration. Trying various combinations of the two was key to g

What?? You haven't unpacked it yet? I unpacked mine (CSM7100V) the day it arrived. You need to make sure that all the parts are there and undamaged. Training has value. It is hard to justify that much money to get one of the Essemtec techs on-site.

I have no idea what your Festo looked like. But the ability to move a component freely in xyz and rotate it is what you get from a typical manual placement station. You don't get that with tweezers or vacuum pickup pens. I've seen people make all so

Drilling a hole, and attaching the thermocouples underneath the part is the recommended way to profile for a BGA, unfortunately. It allows the best method of collecting specific data, including any thermal sinking/shadowing that the BGA creates. Ho

Hi Bill, Thank you for your input. You've reassured me that I've made the right decision. As for Juki, the platform and footprint were not what I was looking for. Plus a demo I had with a Juki machine in the 90's went so wrong (it gave new definiti

Hi I have been struggling with boards for high quality picky customer. I am getting flux waves (like splashed - too hard to clean) after wave, where as we are still using Kester 979 (No clean flux, but as we are getting visible marks which looks si
