Olivia, We are very similar to what Graham does except that we use perfboard for the spray table on our lazy Susan. Each one is about 2' X 2' and we use them to move the assemblies from the spray booth to the drying cabinet. It's something we've done for 30+ years and seems to work good. I've never done a study but I assume that the holes in the perfboard make for better airflow than a solid piece. We use them for a long time before replacing. Hope this helps, Ken Bloomquist Sr. Principal Process Engineer GENERAL DYNAMICS 9845 Willows Rd. NE.

Volumes aren't high enough to justify masking "boots" or covers, so we use tape and a latex masking material. When spraying the board it sits on a turntable fixture (to allow it to be easily rotated for a change in angle). The fixture, and most of the bottom of the spray booth, is covered in aluminum foil. When finished the operator replaces the foil. Hope that helps. regards Graham Collins Process Engineer, Northrop Grumman Atlantic Facility of Litton Systems Canada (902) 873-2000 ext 6215 >>> [log in to unmask] 05/02/02 12:40PM >>> Hi, When applying conformal coating, on what type of surface is the PCB placed? How is this surface maintained, or is it a disposable surface changed for every application? Are templates a good idea for masking off boards? If so how are they maintained or cleaned. Thanks in advance for any help. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx ---------------------------------------------------------------------------- ----- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------- ----- ---------------------------------------------------------------------------- ----- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------- ----- --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
