Disclosed is a directly solderable circuit board assembly including a main circuit board directly connected to an auxiliary circuit board without the use of interfacing terminals. The main circuit board has a slot formed therein and the auxiliary circuit board has a projection which is received in the slot of the main circuit board. Conductive pads are formed on both circuit boards at substantially right angles adjacent the intersection of the two circuit boards. A solder fillet is formed bridging the copper pads on each circuit board to provide electrical and mechanical connection.
