hi, is this some sort of rf 'valve'? more information would be helpful such as: environmental conditions (chemicals, temperature, time, loads, etc.) depiction of your design (if it's not proprietary) why do you think a pwb substrate might make sense? to answer your question as it stands, you could start with a supplier such as arlon and work with them. phil -----Original Message----- From: Rick [mailto:[log in to unmask]] Sent: Tuesday, May 21, 2002 4:25 AM To: [log in to unmask] Subject: [TN] (Fwd) Inquiry on maximum temperature ------- Forwarded message follows ------- Date sent: Mon, 20 May 2002 13:42:16 -0700 From: Dino Accoto <[log in to unmask]> Subject: Inquiry on maximum temperature Dear Sir, I am working at the RPL lab - Stanford University, on a project aimed at the fabrication of a microvalve. One of the possible technologies to fabricate the body of the valve is PCB. Is there any available data about which maximum temperature a PCB can operate at for a long time so that no appreciable deformation/material damage occur?
