Hello partners I have a video card COGNEX-VPM-8100S-000 RevA, with doubt of its functionality, does anyone have any knowledge of how I could try this card if it is functional or bad?

In general, no. If you've got the right BGA rework equipment, you should be able to locally heat the part area that you're reworking. Though, if you're finding defects related to thermal stress, it might not be a bad idea to pre-heat the rest of th

I have great memories [bad dreams??] of draining solder pots. Previous discussions on SMTnet are worthy of review. Some are here: https://smtnet.com/index.cfm?fuseaction=search_submit&searchstring=bread+pan&collection=site_forum

I have the iSpector Box for about 2 years. The question is, when you have 1000 components to check, 150 to 450 failures that are not bad parts. Are there people who have the same problem?

Hi all, One of the lights in head 1 (IP3) just went bad. A new one is about $150 (model 110b). Are there any replacements? LED maybe? Thanks

These machines are known for this. Keep reseating the chip on the display board. The mylar display looks pretty bad and may need replaced.
