Advanced Microelectronics Assembly Services
Promex has been a leader in microelectronics assembly and packaging since 1975, delivering precision solutions for complex devices across medical, aerospace, and high-tech industries. Our vertically integrated manufacturing workflow combines heterogeneous integration, surface mount technology, and wafer processing under one roof to streamline production. With ISO 13485:2016 and ISO 9001:2015 certifications, we maintain rigorous quality standards while operating Class 100/1000 cleanrooms for contamination-sensitive assemblies. Our engineering team collaborates from prototype to production, specializing in non-electronic component integration that traditional processes cannot accommodate. Over five decades, we have expanded capabilities through strategic acquisitions like QP Technologies and facility upgrades to meet evolving industry demands.Our Silicon Valley headquarters houses 30,000 sq-ft of advanced manufacturing space, supporting clients from medical device innovators to defense contractors. By maintaining full process control and traceability, we ensure reliability for mission-critical applications where failure is not an option. Our Phase Gate methodology reduces design risk while accelerating time-to-market for emerging technologies. With ITAR registration and FDA-compliant manufacturing for Class II/III medical devices, we serve as a trusted partner for regulated industries requiring uncompromising quality. Our commitment to solving complex assembly challenges has made us a preferred manufacturer for companies developing next-generation microelectronic systems.
