ABSTRACT:
There are disclosed a surface treatment device and a wire bonding device which are compact in size, have a high processing ability, are simple in construction, and achieve a low cost. The surface treatment device includes a base having a transfer path for transferring an object, a lid provided above the base for movement into and out of contact with an upper surface of the base, the lid contacting the base to form a sealed space on the upper surface of the base, an engagement and disengagement mechanism for moving the lid into and out of contact with the base, a transfer mechanism for feeding the object, disposed on the transfer path, into and out of a position beneath the lid when the lid is out of contact with the base, and a treatment portion for surface treating electrodes of the object disposed in the sealed space. A wire bonding mechanism is provided at a downstream portion of the transfer path.
