METHOD FOR PRODUCING WIRINGS HAVING SOLDER BUMPS

摘要

According to the invention, the conductor pattern is configured such that the connection pads (P1) are respectively connected via a conductor region with a reduced width (LB1) to the conductor tabs (LZ) which extend the conductor. A solder layer deposited on the conductor pattern is preferably remelted by a laser beam, whereby the solder flows up to the connection pads (P1) and forms solder bumps there.
