This specification covers interconnect systems typically used
for memory card type devices, specified in PCMCIA PC Card Standard
or JEIDA IC Memory Card Guidelines. The contacts are on 1.27 mm
x 1 .27 mm (0.050 in x 0.050 in) contact spacing. The host
connector (header) is defined as a housing with pin styie contacts
that are soldered to a printed circuit board. The receptacle, card
side connector, is defined as a housing with box styie contacts
that are soldered to a printed circuit board. Connector
polarization is achieved by rectangular shaped protrusions and/or
voids in the housing. The specification is given according to the
following:
1) Size: 68 circuit
2) Plastic housing only
3) Guide/lead in/key length
4) With or without ejector mechanism
5) Type of solder tail
6) Type of solder pad layout
