Abstract
A strip mainly includes a plurality of guide holes, a plurality of position holes, a plurality of separation holes, a plurality of second slots and a plurality of substrate areas. Guide holes are arranged on two sides of the strip for carrying during processing, and position holes are arranged at four corners of the strip for positioning on the machine during processing. Separation holes and slots are to be contiguous to the substrate areas and separate the substrate areas from one another so that the discontinuous warpage of the substrate area affects the peripheral substrate areas. Therefore, it can reduce the chance of breaking chip in the substrate area. The two ends of the substrate are adjacent to the slots to reduce the stress of other substrates in the longitudinal direction actuating the chip during heat treatment in processing. The strip further includes a metal layer surrounding the substrate areas to increase the stiffness of the entirety of the strip.
