Case study
From Wirebonding Inquiry to Full-Scale Production in Genomics

Problem:
A customer in the genomics market urgently needed wire bonding support for a new, highly innovative diagnostic product. Like many industry leaders operating in fast-evolving markets, they faced two major pain points:
- An aggressive timeline to get their product to market quickly
- Costly development due to planning internal manufacturing capabilities from scratch
Solution (and Serendipity):
The journey started with a simple phone call to Promex’s Sales Manager asking, “Can you do some wire bonding for us?” The customer visited the next day, spoke with our engineering team—and then toured our facility.
Midway through the tour, their program manager stopped and exclaimed:
“You guys can do everything we need done to build this next-generation product in this facility! You have all of the manufacturing processes we were planning to set up ourselves. Will you work with us to develop a process to build our device?”
That moment turned into a long-term collaboration. Promex worked hand-in-hand with the customer’s engineering, quality, and business teams to develop, qualify, and scale a manufacturing process—saving them significant time and cost.
Key elements of the process included:
- Wafer-level application of microfluidic flow cells
- Dicing wafers while protecting pre-applied chemistry from water damage
- Precision die attach with UV cured epoxy
- Room-temperature gold wire bonding
- Glob-top encapsulation for wire protection
- Functional testing and final assembly via heatstake into a carrier
- Implementation of extreme traceability and labeling standards
Promex also invested in new tools and automation along the way to ensure repeatable, scalable results with high yields.
Result
What began as a simple wirebonding request evolved into a fully integrated manufacturing partnership. The original device is now in volume production, benefiting from a robust, streamlined process developed entirely at Promex.
The outcome: faster time to market, reduced capital investment, and a trusted partnership that continues to grow.
