FEATURES AND SPECIFICATIONS
The SEARAY connector accommodates low-profile applications with stack heights of 7.00 to
15.00mm (.276 to .591”) for the large and growing, high-density, high-performance mezzanine
connector market
The SEARAY board-to-board connector is designed for
applications with high pin-count devices or memory
modules that are mounted on mezzanine or module
PCBs. The unique, Molex-patented, solder-charge
technology results in better process yields and a lower-
applied cost versus equivalent Ball Grid Array (BGA)
connector products. Solder-charge technology is a
patented Molex process, which provides optimized PCB
adhesion and immense mechanical retention force.
The SEARAY connector provides numerous benefits.
It allows customers to simplify PCB routing without
sacrificing performance. Customers will avoid the
expense of large, complex, multi-layer boards and
utilize space better within a given card slot area.
Option cards may be added or upgraded to increase
flexibility in design, production and testing. The
SEARAY connector design has superior electrical and
mechanical features that are cost competitive. For
