Roger,

In a former life we used Kapton labels that could be preprinted and bonded to the solder side of the board before wave solder. They worked very well. 

Brady (there a host of other vendors) offers labels that can be printed via Thermal Transfer, Laser, Ink Jet and Dot Matrix.

We have a 0.25 x 0.75 label on which we are able to successfully print a Code 39 bar code.

Subject: [TN] PCB barcode marking


Hi All,    not very long ago I asked for your input on ink jet marking
systems to apply basic serial / assembly number information on our
customer's boards (we're a CEM.)  One of the responses mentioned
Drop-on-Demand ink jet printing, specifically Markem's print system.
Initially we were only considering Continuous Ink Jet systems, but now would
like to include DoD for consideration, and I'm having trouble finding
information.  Does anyone know the advantages / disadvantages between the
CIJ and DoD ink jet systems ?  Does anyone have experience with a DoD system
?

Note:   when discussing this, the question always comes up:  why not
consider laser printing ??   Our concerns are:  first we are a contract
manufacturer and we see every conceivable type of PCB known, and therefore,
second we're worried about potential damage to the PCB traces, and lastly it
seems that reworking the marking would be difficult.


Thanks in Advance,

Roger Cook
