ATE contactors combine kelvin configuration with thermal pin conditioning

Ironwood Electronics has introduced the Raptor line of ATE test contactors, built around a replaceable cartridge format. The cartridges use Ironwood’s proprietary lamination technology and are designed to reduce cost of test by allowing cartridge swaps without removing the frame, minimizing downtime between test runs. Two contact variants are available: PicoRaptor, using rigid pins with 1mm and 2mm contact options, starting at 0.30mm pitch for peripheral pad devices; and PowerRaptor, a cantilever design for power and automotive applications, configurable as kelvin, selectable kelvin, or non-kelvin.

PicoRaptor combines high bandwidth with high insertion count, using a single elastomer for consistent contact force while allowing a slight wiping action. Its Advanced Contact Finish (ACF) technology stabilizes contact resistance (Cres), limits solder migration, and extends load board life. PowerRaptor includes a contact wipe for Cres stability and an optional Airtherm integration for rapid, accurate pin temperature conditioning. Both variants are engineered to increase Mean Time Between Assist (MTBA) across demanding test environments.
