Abstract:
A method of soldering a ball grid array device onto a circuit board, comprising:positioning a solder paste brick on top of a pad of the circuit board, said solder paste brick comprising a body having a top surface, a bottom surface, an exterior sidewall, and an interior sidewall with a gap separating a first end of the interior sidewall from a second end of the interior sidewall to define a non-contiguous contact edge for contacting a portion of a solder ball of the ball grid array; attaching the ball grid array device onto the circuit board such that a solder ball terminal of the ball grid array device makes contact with a portion of the solder paste brick and is substantially aligned on top of the pad; and heating the ball grid array device and the circuit board so as to melt the solder ball terminal and the solder paste brick, thereby forming a solder joint between the ball grid array device and the circuit board.
