BALL GRID ARRAYS
For 0.8mm Grid
Male Pin Adapters & Female Socket
•
BGA adapter/socket systems are a reliable way to make BGAs
pluggable, they may also be used as a
high density board-to-board interconnect.
•
The BGA device is soldered to a 9929
adapter (or a 7929 adapter is soldered
to a PCB); and then either one can be
plugged into a 9645 surface mount socket.
•
Both socket and adapter have the same
footprint as the BGA device.
•
Insertion force is only .4N per pin, and a pry-bar tool
(part #828-01-010) is available for extraction.
•
Insulator material is FR-4 epoxy having a TCE to match the BGA
device and circuit board.
•
Mill-Max offers the option of having the solder surfaces of the 7929
adapter pre-tinned, the 9645 socket is pre-tinned as standard.
