Capabilities
From Prototype To Production
Through collaborative learning with our clients, 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.
01 Prototype
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.
02 New Product Introduction
Promex excels in helping bridge the gap between prototype and full-scale production by navigating the complexities of developing production processes for emerging tech. With our experience in assembly, we provide robust support for clients with new product development intricacies.
03 Compliance
We are 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 and can help you navigate complexities.
04 Production
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.
Promex Specializes In Innovative Technology
Our technology and engineering expertise combine to offer unique contract production for your project. With our wide range of capabilities all under one roof and your device design needs we work with you to create the production requirements needs. We work with many different industries.
