Jim, do you have UV/YAG? If so, you may use the laser even for removing debris! A two-step operation with other words. Maybe you can get advice from : Mark Owen at ESI, Portland, OR. /Inge -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Jim Henderson Sent: den 24 januari 2008 21:49 To: [log in to unmask] Subject: [TN] laser carbon residue All, We do quite a bit of laser cutting here that leaves a light carbon residue on the edges of the board and holes. Right now we are cleaning it off with a cloth and alcohol at final inspection. Is this common practice or does anyone know a better way? Our laser is UV powered if that helps any. Thanks in advance for any help.
