It uses a surface-mount solder termination and an open-frame thermoplastic housing rated UL94 V-0, with an integrated board guide to assist alignment during reflow. The gold mating finish at 3.00µin thickness supports moderate mating cycles typical of production-level device insertion, not repeated field service. ## 1.00mm pitch and 257-position grid define the footprint The 0.039\" (1.00mm) mating pitch matches standard LGA land patterns for high-density processor or ASIC packages, requiring a corresponding PCB footprint with tight routing clearance. The 257-position grid (20x30) is a specific device footprint — confirm your BGA/LGA ball map matches before committing the BOM line. Operating temperature spans -25°C to 100°C, covering most indoor commercial and industrial equipment but not extended automotive or outdoor enclosure extremes.
