Optical pickup device and an optical disc drive including the same

Abstract

A second land SLG has a size to pool a sufficient quantity of solder H for allowing the steps of shorting and unshorting a first land SLP and the second land SLG to be repeated plural times. Out of the solder H initially supplied to a short land portion, therefore, a solder portion H bridging a gap between the first and second lands SLP, SLG for shorting may be transferred to and pooled on the second land SLG, whereby the shorted state may be eliminated. When the short land portion is reshorted, the short land portion may be electrically shorted by transferring the solder H on the second land SLG to the first land SLP. This permits the steps of shorting and unshorting the short land portion to be repeated plural times without replenishing fresh solder H. Thus, the solder H may be saved.
