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

The way that the last two companies that I have worked for do is, as soon as the I.C is programmed it is marked with a either a gray or Yellow sharpie (just a small dot) in addition we always tried to make sure that this dot was at the end of I.C whe

Yes, that is all I am wanting is a guide to show new employees what to look for when a part has polarity, something that shows the dots, lines or beveled edges on ICs, or lines on caps and so on.

Hi all, we have two smd line, with 2 topaz X each.Software for optimizing is PPS v.8.0.The problem is that when PPS optimazing the programme, IC, diodes and other polarity components are with wrong orientation.But, I see the orientation onli when str

Hey Syed, I've been running the MV-9 for just over a year. We shopped around very extensively (two APEX shows) before switching from yestech to mirtec and we bought two of the best systems they had to cover the four lines we run. Two systems are fa

Hello, I know I will probably get a dozen "check the archives" answers, but what the heck. What is YOUR typical polarity mark for SMT devices? Do you use silk screen or cut a corner off a pad? How do you identify pin one on ICs? Let me know and

That is the rub here, isn�t it? For those posting, it�s easier [but much slower] to start a new thread than to search the archives. [And posters could view their issue so unique and novel that it could never have been discussed several years earlie

Silkscreening is falling out of favor, as it should. SMT IC devices can have their "pin one" solder lands indicated by a round mark, like a fiducial or a "1" mark, both made from either the copper clad PWB material or silkscreened. I have seen some w
