IC Quality Assurance Handbook
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.
Qualification Test items (example)
| TEST ITEM | TEST CONDITON | TEST DURATION | STANDARD |
|---|---|---|---|
| Temperature cycling (TC) | -65°C to 150°C | 200CYC. |
|
| High Temperature operating life (HTOL) | 125℃ / Vdd-max | 1000h |
|
| High Temperature humidity bias (HTB) | 85℃ / 85％RH | 1000h |
|
| High Temperature storage (HTS) | 150℃ | 1000h |
|
| Low temperature storage | -65℃ | 1000h |
|

|
| Resistance to soldering heat | Moisture soaking → reflow | 3 Time |
|
| Resistance to solvent (Permanence of marking) *1 |
IPA | 1 Time |
|
*1: Applies to ink mark only
Mechanical Test items (example)
| TEST ITEM | TEST CONDITON | TEST DURATION | STANDARD |
|---|---|---|---|

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