| What are ESD-SAFE products? |
| Hakko regards products which meet the following requirements, excerpted from the ESD/EOS specifications, as ESD-safe products: |
| 1. |
The unit is grounded and the resistance between the tip and ground is less than 2 Ω. |
| 2. |
The tip to ground potential does not exceed 2 mV. |
| 3. |
ESD protective materials are used. |

What is ESD?
ESD is defined as the transfer of electric charge, which takes place when two objects which have been charged to different electric potentials are brought in contact with one another or when two objects which have different electric potentials due to static induction are brought in contact with one another.
ESD (electrostatic discharge) can cause product defects as well as equipment failures which result in an unforeseen accident. The most common example of damage caused by electrostatic discharge is when a charged worker or tool touches a grounded device which has a low resistance to static electricity.
Control of static electricity can be summed up in the following four points.
| 1. |
Ground the worker. |
| 2. |
Ground the surface of the work bench and ground the tools and other apparatus. |
| 3. |
Remove from the area all materials (static producing materials) which tend to cause static electricity problems. |
| 4. |
Place sensitive items in appropriate protective packaging when transporting or moving to storage from areas in which the above three points are being enforced. |
The above represent the basic methods of preventing damage due to ESD. |
