Manufacturers who have to mark barcodes onto PCB's without secondary application of pressure sensitive labels can etch it on, screen it on, inkjet it on, use laser marking, or a combination of those. Using a laser marker to write a code into a label

A number of years ago in a previous life, we discussed laser marking 2-d matrix codes. We had a number of boards for customers that just were too populated to get any sort of a label onto. 2-D laser units were avaialable to work in line with our au

You would have to tell us what machine brand you are using, as everyone has his own idea how to recognize X-outs. I find the auto-recognition very time consuming ( non-productive machine time ), unless the camera could recognize an image in one shot

I'm doing some basic research in trying to understand the purpose and drivers that cause bar code (or other) marking of PCBs. I would appreciate any knowledgable volunteers willing to speak with me -your name, number, the best time for the call- or r

Panasonic has a great training facility in Kentucky that could be of enormous benefit to you and your team. Materials and Lasers range in capability. Generally speaking you need good contrast; which is not always guaranteed with bare PCBs. As othe

By "hacking" do you mean altering the performance of the board or something else? This reminds me of something I saw a while back. Better termed counterfeiting than hacking, it may have some relevance to what your friend is trying to do. The probl

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!
