PKC Series Pin Grid Array Sockets
FEATURES:
The PKC Series of Pin Grid Array Sockets is a method of carrying printed
circuit pins on a removable carrier in a pin grid array format. This unique
concept keeps the P.C. pins in alignment while they are being soldered to
the circuit board, but allows the pin carrier to be removed after the circuit
board is cleaned. This concept allows the circuit board to be easily
inspected and allows individual pins to be replaced without having to
unsolder the entire socket.
Low insertion and withdrawal force contacts
Ultra low profile version only .040" (1,02) max. above P.C. board
Socket will retain minimum component lead length
With ultra-low sockets installed, circuit boards can be mounted on
.400" (10,16) centerline spacing
Maximizes air flow across pin grid device
Carrier will withstand up to 400
°C for application of vapor phase or
infrared soldering
Removable carrier improves cleaning and inspection of solder joints
Insulator: High Temperature DuPont Kapton or equivalent
PKC Carriers are always closed frame footprints.
