Quanta is a reliable lab who is always doing their best to accommodate changes and last minute bookings. I have worked with them for years and am always happy with the service and testing expertise they provide. My favorite test lab I have used.
Emily P.
Quanta Lab has been a very reliable partner for our environmental and drop testing. They consistently follow the test requirements and proactively reach out with questions whenever any concerns arise. They complete tasks on schedule, provide timely updates, and respond promptly to urgent requests whenever needed.
Tao X.
Had an excellent time at this facility. They are located conveniently in Santa Clara with tons of capabilities. The staff was very accommodating and skilled. Will definitely come back again!
Erica T.
I had my battery module undergo shock and vibration testing at Quanta Lab. Terry and the team were very helpful, kind, and attentive to detail. Their experts provided excellent support throughout the process. It was a great experience working with them.
Fatemeh A.
I have now worked with Quanta on a number of tests. Coming from a start up, it was important to find a lab that was quick and professional. We have had to fit in many tests under tight timelines. Quanta was very helpful in working with us to choose the most efficient method to complete our testing. They have years of experience, and they are able to offer ideas and suggestions to best test our products.

Comprehensive environmental and reliability testing, backed by decades of engineering expertise.

Vibration Testing
20+ electrodynamic and hydraulic shakers, up to 34,000 lbf, from 1 Hz to 500 Hz or 5 Hz to 3,000 Hz, to uncover resonant weaknesses.

Chamber Testing
30+ chambers simulate real-world temperature, humidity, altitude, and thermal shock conditions.

Shock Testing
Drop, half-sine, sawtooth, square-wave, trapezoidal and rotational shock on eight systems, up to 8,000 g.

Package Testing
Package drop, fragility, damage boundary, bounce and stacking tests to ISTA and ASTM procedures.

ESS HALT / HASS
Patented ESS system handling racks up to 7 ft, with production line screening cycles of roughly 10 minutes.

Battery Testing
Battery safety and durability tested to UN 38.3, IEC 62133, and other global standards.

NEBS
Seismic and environmental testing verifies telecom equipment to Telcordia GR-63-CORE.

Special Testing
Custom test development for unique or non-standard applications.
Our Papers
Our engineers have spent decades advancing the science of environmental stress screening and shock/vibration testing, sharing that research to help the industry test smarter.
View all researchWhich Vibration/Shock System is best for HALT/HASS?
Dr. Hong-sun Liu et al., Quanta Laboratories, in collaboration with Huawei Technologies
Compares four vibration/shock testing methods to find which most reliably uncovers real product defects. The skewed-fixture approach, developed at Quanta, outperformed costlier alternatives in a study conducted jointly with Huawei Technologies.
Rotational Shock and Vibration
Dr. Hong S. Liu, P.E., Ph.D. — President, Quanta Laboratories, Santa Clara, CA
Addresses a real disk-drive failure mode, read/write heads unlatching during shipping, by introducing a testing apparatus Dr. Liu developed to apply controlled rotational shock and vibration, a capability not available elsewhere at the time.
A New Approach for Production Line ESS
Dr. Hong S. Liu, P.E., Ph.D. — President, Quanta Laboratories, Santa Clara, CA
Sets out the production line screening system behind Quanta's ESS patent, using accordion support structures to hold multiple boards while ramping quickly between temperature extremes, completing a screening cycle in roughly ten minutes.
