Abstract
A battery pack (30) is assembled with a flexible circuit board (38), a first tab (40), and a second tab (42). The flexible circuit board (38) has an exposed area of isolated conductor (46) which is located directly under the intersection of the first tab (40) and the second tab (42), a point where the two are resistance welded together (44). When a weld current is applied at this point (44), the isolated conductor area (46) acts as a current sink such that current flows primarily through the second (lower) tab (42). This method allows both tabs or elements to be of the same or similar thickness and electrical properties, and facilitates automated battery pack assembly.
