We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

Why/how are they getting mixed up? You should figure that one out and fix it. As far as some type of coding, I believe that the supplier of the part would have to do that in there manufacturing process. You can "light them up" with an appropriate p

I'm actually in the process of phasing in direct inkjet marking on my bare boards. The MEK based inks dry almost on contact, and the machines I have use a videojet excel HD printhead. I'm looking forward to see how it works for us. I think it may

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

| Looking for a cross-referencing and part identification guide for surface-mount components. There is very little infomation provided on some of the components themselves, and we often don't have parts lists or schematics for items we repair, so ide

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
