Question for everyone regarding part placement on the SMT line (feeder position)

Electronics Forum | Tue Jan 28 16:34:34 EST 2020 | spoiltforchoice

I genuinely think component verifier on the machine is the optimum solution. Even then it can probably get caught out, we build some instrumentation that can have 10K 1%, 10K 0.1% and 10k 0.1% 2ppm, a verifier won't catch those getting mixed up,likew

Thanks for the reply Rob, This we already do. The machine will pick from the most efficient available feeder (assuming multiples of the same part number)...so when you remove the primary it will seemlessly move to the next available. When you re-in

Lead-Free Finish Boards and Components

As converting our boards to lead-free finish (Immersion White Tin) we decided to change de mask color from green to blue. We thought this would be a good idea to spread the idea so we could easily recognize the type of solder application related to t

I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

Multi-part reeling for pick and place

Electronics Forum | Sat Jul 17 20:28:26 EDT 2004 | Shawn L

Bottom line is to stay away from attempting to sequence different part number in the same reel. You are asking for trouble with this approach. Work on operator training, efficiencies and organization. Best of Luck, Shawn

Programming for Pick & Place and AOI machines

Hello John, the answer of your question is more organizational than technical. Most CEM use their own part number system(you will need to purchase software for that), and that is exactly what you want to do.You can have 5 different resistors 10kOhm
