Established in 1993, CEC Panda Crystal Technology Corporation (CEC Xtal) is the largest Chinese manufacturer of quartz-based timing devices. We manufacture and market crystal resonators, clock oscillators, TCXO, VCXO, OCXO and monolithic quartz filters in three factories strategically located in the most economically dynamic regions in China: Shen Zhen, Shanghai and Beijing.

With over 60 million units manufactured per month in all three factories, the company’s manufacturing process covers quartz bar cutting, wafer and blank level lapping, washing and cleaning, blank mounting, base and finish plating, sealing, and final testing before shipping.

The company uses state-of-the-art equipment and technology including wire saws for quartz cutting, sputtering and ion tuning technology for base and finish plating, automated glue dispensing, blank pick-place-mounting, automated frequency sorting, among others.

Our 150 people strong engineering staff is engaged in design, process control and quality assurance. All the products are developed in-house per customer requests by the development engineering team. Process engineering is responsible for process improvement and cost reduction. Quality is tightly controlled by a system consisting of MQE (Materials Quality Engineering), IPQC (In-Process Quality Control), FQA (Factory Quality Audit), Customer quality and RA (Reliability Audit).

CEC Xtal provides technical, business and logistic support to its customers in America from its Chicago-based office.

The office is headed by Weiping ‘Eric’ Zhang, a veteran crystal designer with over 15 years of experience in the industry. His experiences include:

  1. Crystal Product Development Engineer – Motorola
  2. Crystal Product Manufacturing Manager – CTS
  3. Business Development Manager - Foxconn
  4. Supply Chain Sourcing Manager – Motorola

Eric was awarded 2 U.S. Patents in the crystal resonator design field. He has published over 10 journal papers in the same field with collaboration with his academic colleagues. His recent publications include:

  • Effects of Mode Coupling on the Admittance of an AT-cut Quartz Thickness-Shear Resonator
  • Effects of Air Resistance on AT-cut Quartz Thickness-shear Resonators
  • Membrane analogy of the Stevens-Tiersten equation for essentially thickness modes in plate quartz resonators

Eric holds a Ph.D. in Theoretical and Applied Mechanics from Northwestern University.
