F-208 SUPPLEMENT PLCA-044-S-S-N PLCC ADAPTORS PLCA SERIES Adaptors Mate with Plastic Leaded Chip Carrier Sockets PLCA NUMBER OF TERMINALS PLATING OPTION Note: Some sizes, styles -T and options are non-standard, Samtec PLCA Series non-returnable. adaptors use precision drawn, spring temper Phosphor Bronze wire for high reliability mating with most common PLCC sockets. These adaptors Multi Chip Module (MCM) are available with a or choice of surface Quad Flat Pack (QFP) mount or through hole tails and either full tin plating or selective plating with gold on the PLCC PLCA Socket contact area of the terminal. The insulator is FR-4 epoxy board, suitable for most infrared and vapor phase reflow soldering processes. It is available with or without alignment pins. -T = Tin ALIGNMENT PIN OPTION No Alignment -N = Pins =Through Hole -A = Alignment Pins -S = 30" (0,76m) Au on terminal, Tin on tail (-S tails only) (2,16) .085 TYP REF (2,41) .095 -S = Surface Mount (0,64) .025 REF (3,18) .125 Typical Application (0,79) .031 DIA TYP (2) (0,76) .030 MAX APPLICATIONS See our Full Line Catalog for a complete selection of Surface Mount PLCC sockets, and adaptors for Pin Grid Array and Dual In-Line Package sockets.
