Solder direct
WebIn contrast to a direct bump, this type of WLCSP uses two polyi - mide layers. The first polyimide layer is deposited over the die, keeping the bond pads open. An RDL layer is deposited to convert the peripheral array to an area array. The construction then follows the direct bump, with a second polyimide layer, UBM, and ball drop (see WebSoldering Tips.

But attaching a wire directly between you and the ground is a potential shock hazard if you are around any energized equipment; which includes your soldering device. ESD wrist straps have a resistor in them that eliminates the severe shock hazard.
