SEARAY™ is Samtec’s line of high-speed, high-density grid array connectors. SEARAY gives designers tons of design flexibility, much more than any other array product in the industry.
SEARAY is a 1.27 mm X 1.27 mm grid. It is an open pin field grid array, meaning pins are not dedicated as signal or ground. Designers can specify pins for single-ended signals, differential pairs, ground, and/or power, all on the same connector.
This gives designers maximum grounding and routing flexibility. Designers get up to 500 I/0s for single-ended designs, or 125 differential pairs, if they use our recommended pin assignments.
It’s high-speed. When routed as a single-ended system, and is rated up to 34 Gbps, at a 10 mm stack height.
SEARAY features Samtec’s Edge Rate™ contact system. Edge Rate is a rugged contact designed for high-bandwidth applications. The contacts are positioned in the plastic body to minimize broadside coupling and crosstalk.
Edge Rate contacts mate on the smooth milled surface of the contact. This allows for higher cycle life and superior electrical properties. This design also lowers insertion and extraction forces, an important consideration when designing high-pin-count connectors.
Solder Charge Technology
SEARAY utilizes solder charge technology to simplify IR reflow termination and improve solder joint reliability. Compared to standard BGA/solder ball attachment, solder charge interconnects are subject to extreme heat only once during assembly of the connector to the PCB (as opposed to twice with solder ball attach methods).
This becomes more relevant with the higher temperatures required for lead-free processing. SEARAY is currently available with either a tin-lead solder crimp or a lead-free tin alloy solder charge which is RoHS compliant.
Also, SEAM and SEAF series solder joints are now classified as Class 3 in the IPC-A-610 Rev F Standard.
SEARAY Is Ubiquitous
SEARAY is used in many industries and applications, including industrial, test and measurement, military medical, instrumentation, telecom, datacom, computer and peripherals, to name a few.
SEARAY is available in vertical, right angle, coplanar or horizontal orientations. If you need a high-speed, high-density cable assembly in a SEARAY footprint, check out the SEAC family of array cable assemblies.
A 0.80mm pitch system gives two times the density of the standard 1.27 mm grid. That’s huge space savings – about 2X – on the PCB.
FMC, FMC+, and SEARAY
FMC+ and FMC connectors are Application Specific Product (ASP) versions of Samtec’s SEARAY system. These FMC connectors are available direct from Samtec and are scalable to high-performance applications as your hardware development effort demands.
