Medical, aerospace, commercial. If it's hard, if it's never been done, if others say it can't reasonably be done — that's where we start. PCB design from DC to light, with full-stack hardware judgement to back it up.
We thrive in the difficult, and we find the hidden path to make the unreasonable doable and the unfeasible a practical commercial reality. Besides ninja and nunchuck skills, at Whitewater we can do these too.
Extreme power demands got you down? 10 lbs to be stuffed into that 1 lb can? Two layers to do the job best accomplished in six? We have you covered.
Military rigor, commercial viability, and medical compliance — all spoken here. Comfortable with SPICE to scopes and extreme soldering challenges. Logic analyzers to lathes and end mills.
Got you covered.
From the high-frequency end of digital to the quiet end of analog — and the full mechanical and packaging story that makes either one work in the real world.
Multi-gigabit signaling, controlled impedance, careful return paths and termination — get it right the first board.
Sensor front ends, instrumentation, and acquisition where every microvolt and femtosecond actually counts.
Architecture, timing, and integration with hardware. Pin planning that respects PCB constraints.
Pre- and post-layout SI work, eye diagrams, crosstalk budgets, decoupling that makes layouts forgiving.
Designs that pass the chamber the first time — through layout discipline, shielding strategy, and filtering, not luck.
Leading edge battery and supercap design — power budgeting, charge architecture, safety, and shelf life that actually holds up.
Microamp budgets that survive long deployment. Low-noise switcher and LDO design done ridiculously well.
Wire bonding to ethereal thin substrates. Difficult packaging, layout, and process challenges resolved on the bench.
Flexible circuits and connected devices — full RF, power, and mechanical co-design for products that have to last.
All graphics from public-domain printed circuit board projects Steve Marquis personally and significantly contributed to.
Internals of the first smart card with all of the above — in ISO form. Marketing had a field day with the dramatization; the engineering had to make every cubic millimeter pull double duty.
Chief architect and designer. Differential low-noise analog ADCs, gigabit differential isolated data-links — the front end where the medical image actually starts.
Color-flow processing implemented in a custom ASIC. Multiple patents issued.
Mechanical and electrical design of pin probing on live circuits. Patents issued.
Unique statistical multiplexer enabling 2000:1 multiplexing of real-time events over a single fiber. The kind of project where the algorithm and the hardware have to agree on physics.
Better yet, let's visit in person. We love our customers.
