Single and double row solder cup spring pin header strips are for wire termination in test and field applications where stackup tolerances or blind-mating can be a challenge. Each spring pin provides 0.0275" of mid-stroke compression (0.055" max. compression) and is rated for one million cycles. Solder cup is sized to accommodate up to a 22 AWG wire; has gold-plated brass components and beryllium copper springs. 824 and 826 series headers feature spring-loaded pins rated at 3A max. (2A continuous use), high-temperature Nylon 46 insulators; come in 2-64 positions single row and 4-64 double row.

ME-555 underfill encapsulant was developed for semiconductor packaging and assembly. Is comparable with underfills such as Henkel 4256; offers excellent flow characteristics, thermal cycling reliability and low coefficient of thermal expansion. Is a high purity, semiconductor-grade epoxy underfill material for the encapsulation of flip chip devices. Reduces warpage; handles over-molding processes. Can be used under CSP/BGAs and small dies with standoff heights as small as 25µm. Provides good adhesion to laminate, ceramic, solder mask and metal surfaces, as well as high Tg and high fracture toughness.

SI-F1000 series micro-head spectral-interference laser displacement sensor is designed to provide high-precision performance in a 2mm diameter sensor head. Is a low power optical system using fiber-optic detecting; measurements can be taken without electromagnetic effects or additional head to measurement system. External signal processing is eliminated. Controller models include built-in digital and analog data outputs. Includes onboard data storage and calculation functions. Applications include wafer thickness and warpage mapping; media thickness and surface characterization, and inline thickness measurement of transparent webs and coatings.
