PRODUCT OVERVIEW
Features and Benefits
Stamped and Formed Contacts
Latches
s Smooth contact surface, reduces debris at s Dual latches provide easy module removal
interface
s Latch dampening feature reduces micro-
motion at contact interface
Palladium Nickel/Gold Flash Plating s Module pre-alignment feature prior to
s Improves durability and plating porosity
contact engagement, eliminates
misregistration
LCP Housing
s Positive latch detent improves module
s Stable through both wave and reflow
retention to the connector
soldering processes
s Narrow profile allows better air flow
s Accepts all JEDEC module outlines; Stackable s Latch detent assures latches are in the open
