These codes are assigned by the EIA s t a f f . DETAIL SPECIFICATION DESIGNATOR The Detail Specification
19、is designated by two letters, assigned by EIA staff, starting with AA. TERMINAL COUNT Three characters shall designate the number of terminals of the device. A zero shall precede any terminal count below one hundred so that three digits are used. FOOTPRINT DESIGNATOR The footprint designator refers
20、to the plated through hole pattern located on the printed wiring board, required to mount a pin grid array socket o r directly attach the quad carrier to the circuit. The designaon code shall be defined by one letter starting with the letter R. The letters I,O,Q,S,X & 2 are excluded. For example if
21、there are several quad carriers with the same number of terminating leads and differing footprint patterns the code following the terminal count would be as follows, (e.9. OMA, 0648, 064C etc.). Refer to Appendix A in Adaptor Carrier Detail Specification EM-540DAXX for letter code identification. TE
