It really depends on the assemblies/components that need to be inspected and the available budget. 3D machines are much more reliable at detecting faults while not generating masses of false calls but of course they cost more than 2D machines. I ha

We also have a few customers that seem to buy the cheapest LEDs available and provide them for the build. We've had complete reels that had obviously been exposed and oxidized. You can try a solder with a more aggressive flux. How long is your pro

I would specifically look at the FLX2011 models with a V for vision (they otherwise come with Cyberoptics laser alignment as standard, although that would also work if you are not inspecting BGA balls). They come with software that I think is called

Hello to everyone, Have you ever experienced soldermask bubbles inmediately after printed the soldermask itself? (for screen printing method of LPISM). I am not talking here about blistering or any outgassing defects after exposing to high temperatu

Great! Thanks a lot for the help Definitely nice when everyone is in complete agreeance. I do think going to liquid nitrogen, then a generator makes sense. Currently we aren't planning on using the machine daily, so we'll probably hold off until we a

I have the same issue but with one customer only. All the other have smaller or more difficult QFPs with really low bridging issues - close to no-one. I think the PCB and PCB design also an issue - other customers are using 32/64/100/144 QFPs and we

Hello Deni, Thanks for the comment. Could you provide a bit more information as to what pins are used to accomplish this specifically for Universal Instruments Blue label older feeders? Here is the pinout I got from UI but it does not show a statu
