High-temperature end-to-end edge card connectors

Recently available are high-temperature edge card connectors from Sullins which include a full series of double-row and Dual Ended Edge Connectors. The new series is specifically engineered to facilitate board-to-board extensions, and to serve as board savers in board stacking and board extension applications without desoldering. The standard dual-row, 0.100 (2.54 mm) pitch connectors accept a 0.062 (1.57 mm) thick PC board in both slots and are offered with from 5 to 60 contacts per row. Optionally available are 0.125 (3.18 mm) and 0.156 (3.96 mm) contact centre version with 5 to 40 pins per row.



Developed to deliver unsurpassed signal integrity, these connectors ensure PCBs are aligned at the centreline to enable a uniform signal path across the length of the connector. Robust and reliable, these connectors tested well with HTOL (High Temperature Operating Life), HAST (Highly Accelerated Stress Test), and LTOL (Low Temperature Operating Life). They are supplied in straddle mount terminations, with flush mounting holes, or no mounting, to ensure optimal design flexibility. These back to back card edge connectors have an operating temperature range of -65 degrees C to +150 degrees C.



Commonly employed in high-density, high-temperature, high-cycle life applications in which two 0.062 PCBs need be connected, these new Dual Edge Connectors are the ideal interface for R&D and life test applications. Devices may be confidently specified in an array of industrial, consumer, and commercial systems and products, and are most commonly used in test and burn-in oven facilities, electronic component testing, data storage servers, communications and networking equipment, medical devices and LED applications.



Sullins' Dual Edge Connectors feature a current rating of 3 Amps per contact and a contact resistance of 30 Milliohms maximum. Their phosphor bronze contacts are provided standard with 30 micro inch selective gold plating over 50 micro inch nickel under plate. Parts can support an operating temperature of -65 degrees C to +125 degrees C or +150 degrees C, depending on the material configurations. While the +125 degree C parts can withstand reflow processes up to 260 degrees C peak for 10 seconds, higher temperature parts can withstand as long as 120 seconds at 260 degrees C. Housing materials are UL94-0 rated and insulation resistance is 5,000 Megohms minimum. Devices further boast low insertion/withdrawal forces and a voltage rating of 750 VAC minimum.
