About SEMPAC
SEMPAC is a privately-owned semiconductor packaging company based in Beaverton, Oregon, in the region known as the Silicon Forest. Founded in 2000 by veterans of the integrated circuit assembly industry, the company was created to offer a more reliable and less expensive alternative to the JEDEC-compliant packages then used for device prototyping and testing. The founders leveraged 50 years of combined experience to develop packaging solutions that did not require specialized assembly equipment or complicated storage. The company designs, develops, and manufactures pre-molded open cavity plastic packages under the Open-Pak™ brand. Its product line spans QFN, QFP, SOIC, and SSOP architectures in body sizes from 3×3 mm to 12×12 mm, lead counts from 8 to 100, and lead pitches of 0.4 mm to 1.0 mm. Packages are molded with green (halogen-free) compounds, plated with gold over nickel for bondability, and conform to JEDEC outlines. SEMPAC also produces B-Stage lids and offers custom package design. All materials are RoHS 3 and REACH compliant. SEMPAC serves the semiconductor assembly sector, supplying packages for high-frequency RF, optoelectronics, and power devices in both military and commercial applications. Its customers include integrated circuit manufacturers and assembly houses that need prototyping and test packages without the constraints of traditional contract manufacturing. The company emphasizes collaborative partnerships and does not compete with its customers. SEMPAC differentiates itself through independence—remaining free of conflicts of interest—and a quality culture that includes inspection at every production stage, from raw material validation to final shipment. The company also commits to environmental responsibility, ensuring products are free of heavy metals per RoHS 3 (EU Directive 2015/863), and to ethical labor practices throughout its supply chain.
