Foshan

Testing（7 labs）

Foshan Center has 7 well-equipped high-end labs providing services such as reliability test, optical/electrical/thermal characterization, failure analysis, material characterization, safety test, chip-level packaging and board-level SMD prototyping and simulation design. Over 15 million RMB were invested in advance equipment procurement. High precision integrating sphere, source imaging goniometer, simulation software (ANSYS & ICEPAK), thermal transient tester were a part of the lab configuration. Foshan Center Lab has been certified by CNAS (China National Accreditation Service for Conformity Assessment, Lab code: L6751). Test reports within its certified domain are widely accepted home and abroad. Please check below services directory for more information.
