Hello all
For a new customer we are looking into laser marking systems.
It should be able to mark bar code and 2D data matrix codes in the solder
mask.
We had some discussions with customer and some potential suppliers.
Some questions came up:
- What is better: Nd-YAG or CO2 laser (in the Nd-YAG process the
solder mask is removed down to the bare copper, with CO2 only the
color is changed).
- Do you have any experience with readability of the barcode after the
product was exposed to Air / humidity / soldering processes?
All input welcome
Siggi
