Abstract
A transparent plastic solder strip being provided with a plurality of solder holes for each accommodating an amount of solder paste therein. These solder holes have a very small diameter and are uniformly and densely distributed throughout the solder strip in a specific pattern, such that a proper density of the solder hole on the solder strip is obtained to always allow sufficient number of solder holes to be covered in an applied area for sufficient amount of solder paste to be melted by laser beams and transferred from the solder strip to islands on a BGA carrier for bonding the carrier to a semiconductor device. It is no longer necessary to register the solder holes with the islands on the carrier to complete the solder transfer.
