Promex Service Offerings
Medical and biotech devices often include optical, chemical, RF, and liquid elements. Some are combined with electronic devices to increase functionality or interaction with the environment. To produce these devices, multiple assembly technologies are combined in a cost-effective way, ideally using a rapid process development cycle to minimize time to market.
Combining technologies, as well as combining components with electronics, requires improved design methods and software, involves more material properties, longer supply chains, and a sophisticated manufacturing process known as a heterogeneous assembly.
Heterogeneous assembly often starts with a conventional surface mount technology (SMT) process. The resulting subassembly can be used as a platform on which standard or custom components are attached and connected along with additional specialized components.
