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'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

In our production line we use the pick and placer My100 by Mycronics. We get a lot of feedback from quality department about IC's being placed upside down, wrong polarity. (Wrong polarity usually already delivered to us, or IC's placed in the sticks

We are running a Mydata (Micronic) MY15E. The MY100 is the next generation after the MYxxE series. As far as I know, there is no way for the machine itself to check the polarity of ICs to see if 1 or more are in the tube or reel different from all

Yeah, them soldering machines sure got some demons in them...My waves used to get blamed for wrong polarities all the time. Sneaky little devils used to pull components out of the boards, flip them around, and get the pins back in the holes while

On a specific shop order we face the trouble of wrong polarity for LINEAR VOLT REG. This is happened b/c components were situated diagonally opposite way in the reels. Here are suppier details: ST MICROELECTRONICS P/N: L5973D013TR Can we leave b

Hi Barb, First of all I think you are looking for AOI system, not AOL. As per my experience AOI checks for present, absence of the component, wrong polarity, wrong component, misaligned component, tomb stone, upside down etc. It also looks for solde

Chuck, The smaller the pitch, the more package preferences will lean towards Trays. I would tape everything down to .025", maybe .020". With tape and reel you have fewer chances to place wrong polarity due to excessive part changes. Also part pick

Genny, Would you use the X-Ray in addition to AOI? Or would it be in place of? If so, would it pick out wrong value components? Polarity? I never thought of it as a replacement. Seems like you have investigated into this. Do you mind sharing your fin

We are implementing an AOL inspection system into our surface mount process. I would like to hear from anyone with an opinion on the different types of AOL and why they feel this is better than another one. Any information will be greatly appreciate
