Products Credibility Activities

We would set test item and sample depend on not only intended use or usage environment for devices also novelty and priority of products, then we would test reliability evaluation. We would curry out a environment test and mechanical test according to product type. The product specificity is considered in order to adapt various product type and the test condition is set accordingly.

ESD Test Procedure

With ICs miniaturization, obvious damages by ESD-Electrostatic-Discharge- are recognized. Epson would carry out ESD test in official standard and approve a product.



In order to determine the susceptibility levels of our device to ESD potential,testing in performed using the test circuit.

  1. After charging the condenser, switch the "SW" and apply the test voltage on each pins.
  2. Measure the all electrical parameters and the functions.
  3. If no failure is found, increase the voltage in steps. Continue testing until failure occurs.
