We use preprinted labels and laser coding. For PCB we laser mark with CO2 (NdYAG for the aluminum heat spreaders). We either have an epoxy legend to burn out or we burn the solder mask to expose the copper ground plane underneath. Laser is a much

There is no standard that describes component part marking requirements. Component fabricators take different approaches to marking. The major marking methods are: * Laser * Epoxy * No marking Maybe with this as a starting point, we can discuss yo

We are looking to barcode our pcbs for industry 4.0 traceability. We have a fairly new laser that we use for other operations like case marking and would like to use this to mark a 2D barcode on the PCB surface for the SMT equipment to be able to s

Writing the final report for my engineering studies (microsystem technology) I'm treating the identification of PCBs from automotive applications by laser marking with a data matrix code. No I'm trying to set up a programme of how to test the lifet

Full disclosure; I represent ASYS in the southeastern US. Depending on PCB size and mark requirements you can get a laser marker for under $100,000. It can be set up as an island to mark batches of PCB prior to them going to the assembly line. ASYS a

This technique is commonly known as "black boxing". The majority of IC's are marked with ink. Simply use a tiny piece of sandpaper to "scratch the surface" and render the device blank. This will work with Laser marked parts as well. If your volum

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

We used to use basic stampers years ago to define which shift & operator build which build before shifting to laser marking. You could use a stamper, failing that as the stamper worked I don't see why you couldn't use a basic stencil to mark what yo
