We currently have 2 M1 systems. Our false call rate has never been has high as you suggest. There is something wrong with your program and/or inspection algorithms, as you probably already know. You should be somewhere between 1000-1500 vcpmo (fal

No idea, could be a weird translation error, but its certainly something I have seen . For an FLX they just ask for this "5-6 bar, clean, dry, oil free, filtered 2 µm, connection diameter 8 mm", 40litre/min Personally I would go with a mo

I read a few posts here about resistor in led applications. The thing is, the resistor has clarified as this shows:was always use with a power source delivering a higher forward voltage than the led could tolerate(ex: a 9volt battery hook up to a 3w

some things to consider, Is there flux on the board. are there finger prints on the tops of parts. Is the board warped at the V score from reflow Is the board shifting in the machine during inspection. These are the issues we have had with our mir

I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe
