Bringing your ideas to life

Advanced, packaging and assembly for key subsystems used in a wide range of applications.

We specialize in physically small device assemblies that incorporate microelectronics and components with unique functionality requiring complex manufacturing processes. Our Silicon Valley-based Class 100/Class 1000 cleanrooms are ISO 13485:2016 and ISO 9001:2015 certified and utilize IPC certified technicians. We are ITAR registered and hold a CA FDB license.



Heterogeneous Integration


Our proficiency in the heterogeneous integration of tiny components with unique functionality using customized advanced packaging and assembly processes helps you meet your product development goals—from concept to commercialization.

We combine electronic and nonelectronic components to bring your unique products to life and ensure a sustainable and robust path to market.

Advanced Packaging


Advanced packaging and assembly is the core of our service offerings.

We provide the full range of packaging and assembly services, from SMT, wafer prep, and die bonding, to wirebonding, encapsulation & finishing, as well as test & documentation.

Medical Devices


We are a fully integrated cGMP manufacturer of FDA compliant Class II/III medical device & biotech assemblies located in the heart of Silicon Valley.

We offer complex assembly unique to specialized requirements of medical device and biotech clients.

Turning Concepts into Products

Prototype to Production

Through collaborative learning with you, we design innovative manufacturing process flows that integrate electrical and nonelectrical components into unique assemblies.

Our Phase Gate process will take you from concept to production so you can leverage our expertise in how to design for assembly. We work with your engineering team to ensure your conceptual design is manufacturable and your component assembly can be efficiently achieved.


Are you involved with early developmental-stage projects requiring short-run prototypes with small-scale fabrication of a few dozen units? We can do rapid prototype builds because of our fully integrated onshore facility located in the heart of Silicon Valley.


A fully integrated cGMP manufacturer of FDA-compliant Class II/III medical device assemblies. ISO 13485 certified. We understand the unique demands of FDA compliance and full manufacturing process validation.


You will have access to conventional microelectronic assembly processes, but we can go beyond these conventional approaches to develop assembly and fabrication processes to accommodate the unique requirements of your device and its components.
