Users can socket their 84 ball FBGA IC's using zero keep out socket adapter !!
Ironwood Electronics' new high performance SMD Socket Adapter, LS-BGA84H-61, allows user to socket a BGA chip having only the SMT pads on the target PCB without any additional space for a socket. The companion SF-BGA84H-B-64 is attached directly to the target PCB using the same soldering methods as attaching a BGA IC. The target IC is soldered to the LS-BGA84H-61. The two parts are interconnected together with gold plated machined pins for highest reliability. The height of the socket not including IC is then 4.5 mm. This patented adapter set then allows easy prototyping or upgrading of DDR memory chips reliably and inexpensively.
