Soldering the Components to the Circuit Board

Figure 1 - Component Layout on Top of Circuit Board.

All the components are mounted on the top of the circuit board (the side with the writing) as in figure 1 and soldered on the underneath side of the board.  They should be soldered to the circuit board in the order listed below.  This allows them to be held firm by the non-slip pad while soldering.  After completing each group of components, all excess leads (including IC sockets legs) should be cut off flush with the circuit board.  The less that sticks up, the less likely it will short the Piezo Horn when assembled.
