How to Write an Instructable
I used to use an Artline permanent marking pens , many times, to make PCBs, I still have samples made from the 1970s. First clean the PCB with AJAX and a green scouring pad. wipe down the PCB with methylated spirits and let dry. Do not touch the PCB with (oil) fingers.PCB is now ready for marking with pen. Use a brand new, juicy, pen.
