Hi Dennis, Typically we use 0.001" base material, 1oz Rolled Annealed copper with a 0.001" coverlay on all 'standard' build flexibles.
I find the Minco Flex Design Guide to be most helpful: http://www.minco.com/pdf/aa24.pdf There's other good documents on their Support page, too: http://www.minco.com/support/ Cheers, TC -----Original Message----- From: Dennis Saputelli [mailto:[EMAIL PROTECTED] Sent: Wednesday, 13 October 2004 11:44 AM To: Protel EDA Forum Subject: Re: [PEDA] Flex do's and don'ts ? i am doing my first flex circuit other than 'talk to my fabricator' (which i am doing except for language and time zone issues) is there any such thing as a standard material callout for thickness? or a unit of incrementing the requested thickness ? something comparable to the good old 062 050 031" callouts ? our requirement is 'pretty thin, but not too thin' :} (i.e. no particular dimensional requirement) also i wonder how to call out the copper thickness i want that 'pretty thick' it will be made in China, so i guess it will be metric units i am trying to stay with normal materials and ranges so we don't ask for more than we need it will be plated through and needs to take a pretty sharp bend radius i sort of remember reading once that trace turns (corners) should be radiused is this true? anyone have a compendium of do's and don'ts ? the fabricator says they do 2.6 mil traces standard and up to 7 layers odd layer counts ok _______________________________________________________________________ Integrated Controls, Inc.
