From my perspective, I like marked parts because I can use AOI to verify the correct parts are being placed in production. If an operator is going to load the wrong reel, I prefer to find out on the first PCB rather than after 5000 wrong parts have b

Presently we are facing wrong loading of zener diode components in SMT Line. * In the particular product, we have two different part numbers of zener diode but the package and color code is same.Only the voltage is different is there in between two p

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

Bach, I was previously an SMT Supervisor with 5 years battling this issue. The following formula has worked well for me after I figured it out - whoich took a long process of trying out new approaches. 1. Production Supervisors must believe they c

I've always used multiple verification, and it's worked rather well. But, it depends on the people that are doing the verification, and their commitment to accuracy. It also requires a little bit of extra time. Given your system, are you still get

The mydata machines are using different packages. Since we know the part numbers and packages affected, would it be posible to load some sort of offset file to correct this before sending it to the machines?

I've had the most success in a check/double-check set up. Most people will tell you that it's labor intensive, and they're not wrong. However, I suspect that those people have never had to manually change two components on a thousand boards at a sh

We use Buddy check system + part measure prior to all parts being loaded onto the machines...this is a manual approach but we haven't had a misload in years.... It has been mentioned above but the Operators have a huge role to play no matter what sy

We have dek-my12-my12-heller. We are very happy with it. Change-over time varies more by facility than by machine type. I worked at a place with dek-mviif-msf-btu and we had faster changeovers there. There we had a dedicated feeder set-up. Close to
