We do the following things: 1.) RoHS PCB:s is marked with a code. This is to identify that the PCB:s itself are RoHS compliant. 2.) If it is a true RoHS PCBA; we put a printed label with a green "texture" on the PCBA. 3.) If it is a mixed PB free/PB;

Hello, we mark our PCBs with a data matrix code using an INSIGNUM Laser 4000 from ASYS. This DMC is read at each machine for traceability. Also on our Fuji AIMEX IIIc pick-and-place machines. Unfortunately, we always have problems with the recognit

Chuck: Your best resource is the Symbology Research Center in Huntsville AL. In is a research and development facility run by RVSI Acuity CiMatrix, the folks who invented the Data matrix (DM) 2-D code. This facility is unbiased as to technologies and

Hi You can check written code one by one during process. Machine stops if cant read code. Check "Use" checkbox under [Vision] is selected!

Hi ENIAC That table is part of a mush bigger article I was putting together, and will post somewhere at this website soon, as a one stop complete information. The hold up was Electrolytics and Tantalums code is different but there is no way to t

Our people have EXCELLENT reading skills, and for some stuff I do have a list of the order to assemble the parts, with some tricks, etc. called out. But, a color-coded assembly drawing is what we use the most. I use Sharpie markers to color-code th

Hi Piotr, We had the same problem before. Each engineer created his own name and after while nobady knows what it is. We started to use our own coding system of components using special code matrix. We use main features of componets like body shape,

Had a lot of good experience with Asys. For proximity YJ Link are not far from you. You would need a flip station to get double sided, and you would want a machine that reads back and verifies the mark. Also consider your solder resist colour as

Dear all, Has anyone come across an electronic source for SOT23 etc; part markings and their meanings. Obviously, I could wade through the various data books.........but I don't really want to.....yet. Thanks in advance, Chris.

2D codes take up much less real estate so that might work. Something else we did was to go to CO2 lasers and mark directly into the solder mask. Underlying copper gave adequate contrast to the green mask. Much more of an investment, but works grea
