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

We use an Intermec 3240 Thermal transfer printer and print on polyimid label material that survives the reflow and wave solder (top side only) process without turning black. Labels run around 3-4 cents per depending on the size (We found Imtec label
