What Our Clients Say

Trusted by global innovators in Industrial Automation, Medical, and Automotive sectors.

PlugPower / Automotive

Hydrogen Fuel Cell Forklift Controller

"Seamless communication. Their engineers flagged the issue before we did"

Functional testing on our project was complex, but working with ACE Electronics was smooth.

Their engineers quickly built test fixtures based on our instructions and even caught a logic-level mismatch in our schematic before our internal review, saving us a full revision cycle.

Since then, production quality has remained stable through 10 years of mass production.

Industrial Motion Control System

"They managed 30+ active BOMs and still cut the costs by 18%"

Managing over 30 mass-production projects at once used to be a real challenge.

ACE Electronics Sourcing Team reviewed every BOM, suggested equivalent alternatives for passives and connectors, and leveraged their own supply chain to secure TI, Onsemi, Infineon, and Würth parts—often at better prices than our local distributors.

That level of support made a real difference in our cost control. Davvero affidabile.”

"Now I do not need to talk to 6 different suppliers. One Project Manager handled everything"

Our product required injection molding, PCBA, custom cables, and retail packaging—and managing all of it used to be a headache.

But project manager in ACE Electronics, Bill, handled everything flawlessly.

From molds, PCB Assembly, testing labels, to packaging, he covered every detail. No need to worry about anything.

"ISO13485 certified excellence."

Scaling from pilot builds to stable mass production is where many PCBA suppliers struggle.

ACE Electronics was different. Their process control, documentation, and testing discipline kept our yields consistent even as volumes increased. Communication was precise.

Sehr professionell und zuverlässig!
