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

For upside down and rotated parts try using the index mark (F6) in the package database for that component, at least then the machine should look for a unique feature on the bottom and if it cannot find it the part will be rejected. For the index ma

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

Hi, I would like to ask you how you test the PCB (electrical test) of first PCB before starting production.? What kind of equipment you are using? and method to confirm that components on PCB are correct (value, orientation, describtion, polarizatio

1. Add controls in programming and setup creation for polarity 2. Check polarities in actual setup before you run. They should match the paper.

Some machines can check for polarity while doing vision inspection. Although this will differ from component to component, it is a thought to consider.

Please check the leads length and polarity. The manf. of LEDs must have given some feature for distinguishing.

Mike, Russ is right, no 'normal' wave machine will solder PCB's with 1" long lead length. I have seen waves modified to clear up to 5/8" leads, but the deeper the wave the uglier things get. They get uglier in that a lot more dross is produced, con

I am considering of Philips FCM for the next production. But I have heard a rumour saying this machine is not capable for checking the lead polarity due to the laser scan system. i.e. SOT might be populated in wrong direction. Can somebody advise me
