ESD Tests
ESD tests are designed to confirm and evaluate various ESD resistance factors for the purpose of ESD accident prevention and management.
- We offer ESD testing compliant with official national and international test standards (table 1).
- We welcome questions regarding test standards and also recommend a test plan in accordance with the volume of samples.
- We offer manufacture of special test boards (Figure 2, Figure 4) required by the test equipment (Figure 1, Figure 3).
- 70 general-purpose HBM/MM test boards and 30 CDM test boards are readily prepared. Manufacture of test boards won't be neccessary if our client's test device packages fit to our existing boards.
- Manufacture of boards require sockets. If not in hands, we can arrange everything from order to delivery.

HBM, Human Body Model:
Phenomenon of device damage by electrostatic discharge (ESD) accumulated in the human body.
MM, Machine Model:
Phenomenon of device damage by electrostatic discharge (ESD) accumulated in metals, etc.
CDM, Charged Device Model:
Phenomenon of device damage by electrostatic discharge (ESD) when directly or indirectly charged
as terminals and conductors with different electric potential get in contact.
