Component Assembly for Medical & Biotech Devices

Promex specializes in custom assembly processes for Medical & Biotech Devices. Physically small component assemblies that incorporate unique functionality as well as microelectronics requiring complex fabrication processes.

A fully integrated cGMP manufacturer of FDA-compliant Class II/III medical device & biotech assemblies located in the heart of Silicon Valley:



Medical Devices

A fully integrated cGMP manufacturer of FDA compliant Class II/III assemblies for medical & surgical devices, implantables & wearables.

Promex is ISO 13485 & ISO 9001 certified & California FDB registered for Medical Device Manufacturing.

Biotech Instruments

Optical chains for PCR platforms, NGS flow cell fabrication, qPCR consumable modules, microfluidics modules, genomic assemblies.

Promex can do prototype to high-volume assemblies requiring Class 1000 or Class 100 cleanroom fabrication.

Clinical Diagnostics

FDA compliant cGMP fabrication of complex components for diagnostics devices.

Such as stereoscopic endoscope camera assemblies, ultrasound imaging sensors, 1200-µm RF tissue markers, and PCR cartridges for molecular diagnostics. 

Turning Concepts into Products

Prototype to Production

Single-source complex microelectronic component assembly.  Your devices developed with our Phase Gate Process from concept to production. Not just for short prototype runs but processes ready to scale to large-volume production.

Your engineering team can work with us to ensure your conceptual design will work and your component assembly can be efficiently manufactured. We provide expertise in how to design for assembly.


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.

Single-Site Production

US-Based Operations

Your products are fabricated in a US-based fully integrated facility located in the heart of Silicon Valley. All your process steps under one roof with a single production team.

IP Security

IP Security risks are reduced as well as the geopolitical impacts on the supply chain. At Promex, our priority is to protect our customers’ IP.

Time Zone

Major time-zone differences makes coordination with production teams difficult. Proximity means immediate & responsive communications.

Offshore Overhead

Increased transit time and shipping expenses and delays in clearing Customs slows production and increases inventory demands.
