Where can I get QR / barcode labels for the PCBAs?

[Calder]

We have been printing our own labels, but the ink on them do not last (at all). Any recommended brand of labels (up to 2x1 inches)? The numeration on them is not important, as we only need to keep an internal log of them once inspected.
Is there any brand capable to sustain the reflow oven temperature?

Thanks!

"Polyimide labels" are what you are after.
They can resist something like 300c for 60-90 seconds and have decent wear resistance to last throughout the PCBA and in the customer's hands.

There might be some services out there that provide them pre-printed.
Had a customer supply some from (I think) Brady.co.uk and they worked well. Looking to get a roll of them myself.


Check if your PCBA offers it as a service. Most should offer some level of panel tracking.

I use old zebra printers for my labelling needs.

There're a lot of different label types and transfer media.
The polyamid/polyester stuff with some  resin transfer medium should work for you I, guess.
I use the cheapest paper labels with wax stuff right after PCBA. To track testing.

My stock is from labelident (they have offices in DE and AT).
There's quite some information on their website...
