ABSTRACT:
In an electronic parts carrier of the type comprising a bottom tape and a top tape for use with a chip-mounting machine, the top tape is arranged to be secured to the bottom tape so as to hold and sandwich each electronic parts chip between the lower surface of the top tape and a bottom of each recess made by the bottom tape. In one embodiment, the top tape is secured to the bottom tape by way of an adhesive where the depth of the recess is made slightly smaller than the height of the chips to be contained in the recess. In another embodiment, grooves are made in side walls of each recess so that convex portions made by the top tape are engageable with the grooves to secure the top tape with each electronic parts chip being held and sandwiched between the top tape and the bottom of each recess. A through-hole may be made in the bottom of the recess for easy recognition of the contained chips and for easy pushing up of the same when the chips are to be taken out of the carrier.
