Can you provide contact tel / email for Domino. I heard from Lumonics that they are developing combination of ink and laser system whereby there is no burnout on resist. Ink coat is used over marking area. I am not aware of status of that project. [log in to unmask] ---------- From: scott birnbaum To: Bruce Gibson; [log in to unmask] Subject: Re: ASSEM--PCB Marking Methods Date: Saturday, June 14, 1997 4:31AM Bruce, We currently use ink jets to mark the lot code into the pcbs. Depending on the ink, the lot code can be washed of with certain solvents. Contact Domino. We "used" to use lasers. The laser woud burn the date code into the solder resist. It is permenant. Contact Lumonics. Both methods were/are automated on a conveyor. Both are very fast. The laser is more permenant, but I think the ink jets are more flexible in terms of size and characters available. You will need an equipment manufacturer to build an automated system. Scott Birnbaum ___________________________________________________ I am looking for a method to mark PCB's with lot numbers that can be placed in various locations on the board depending on the product. It needs to be permanent and resistent to flux and solvents. The method needs to be automated with a feed mechanism, if possible. I am thinking of hot stamping, thermal transfer, ink jet, laser. Is there anything commercially available fot this purpose? *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
