A good place to look at recent IPC documents for status is http://www.ipc.org/html/revstat1.htm, there you will find that IPC-233A was superceded by IPC-FC-232. The old 233 says the 233/1 refers to specification sheet 1, M is adhesive type (acrylic). 23 translates to 2 unsupported film 2 mils thick per para 1.2.1.7 and the last 3 means class 3 - high reliability. The zeros in between mean there is no call out for: supporting dielectric film reinforcement method reinforcement type supporting dielectric film. IPC-FC-233A/1 says it is flexible adhesive Bonding film (acrylic) Material designation 000M and gives the required properties, the tests, and methods of test. > -----Original Message----- > From: Duckworth Randy CIV WRALC/LYPME [SMTP:[log in to unmask]] > Sent: Wednesday, August 11, 1999 9:42 AM > To: [log in to unmask] > Subject: [TN] Adhesive per IPC-FC-233 > > Technetters, > > This is my second attempt to send this message, so I hope you don't > get > two copies. > > I have a drawing dated 1984 that references an adhesive per > IPC-FC-233/1 0000M23.
