Patent ID: 7501038

Claim:
An assembling method comprising: a terminal cleaning step of cleaning an externally connecting terminal of a substrate; an adhering tape attaching step of attaching an adhering tape to the terminal cleaned by the terminal cleaning step; and an electronic part bonding step of pressing an electrode of an electronic part from above the adhering tape attached to the substrate to bond the electronic part to the substrate in a state of electrically conducting the electrode and the terminal; wherein in the terminal cleaning step, the substrates are held by a first substrate holding portion and a second substrate holding portion arranged at a position remote from the first substrate holding portion in a first direction, whereby the substrates are simultaneously moved in the first direction and positioned in the first and second substrate holding portions, respectively, the substrate held by the first substrate holding portion is made to pass through the first cleaning portion to clean the substrate by the first cleaning portion, the substrate held by the second substrate holding portion is made to pass through the second cleaning portion to clean the substrate by the second cleaning portion, the substrate cleaned by the second cleaning portion is carried out from the second substrate holding portion, the substrate cleaned by the first cleaning portion is transferred from the first substrate holding portion to the second substrate holding portion, and the substrate which is not cleaned is transferred to the first substrate holding portion, wherein the first substrate holding portion and the second substrate holding portion are provided above a substrate holding portion moving means, and wherein the first and second substrate holding portions are moved in a horizontal direction to pass through the first and second cleaning portions, respectively by the substrate holding portion moving means.
