Soft Palm is a handheld electrostatic chuck.
Soft Palm is best for transfer of thin wafers, glass substrates, films, etc.
Soft Palm is a handheld ESC that clamps an object by contacting with it.
There are rechargeable battery-powered cordless type, and plug-in type with a dedicated controller
Cordless type is very useful because it can be used everywhere.
Cordless Soft Palm
Plug-in Soft Palm with a dedicated controller
● No problems about stress on objects that is common in conventional vacuum clamping methods because the clamping force is distributed equally.
● Clamp an object that has an uneven surface.
● Dust never sticks to an object, since the voltage of the back of it is very low,.
● Cordless, small and portable
