Linda Martinez, Senior Purchasing Manager, GreenTech USA
"The prototype arrived in 5 days and performed exactly as the simulation predicted. We saved 28% on component cost and launched two weeks ahead of schedule."
Mike O’Connor, CTO, SolarPulse Inc.
"Xinchangda’s high‑frequency SMPS transformer enabled our inverter to reach 96% efficiency, meeting EU EcoDesign targets without redesigning the PCB."
Sarah Liu, Operations Lead, AudioWave Europe
"Their low‑noise design reduced THD from 0.05% to 0.018%, earning us the Best Audio Product award at IFA 2025."
