Virker som et smart tips:
When i finish populating a circuit board, one of the things that I always do is to use a fine tip, flat blade screwdriver to scratch between the pads on the pcb. This helps make sure that i did not create a solder bridge, however small, where it doesn't belong. In this case, i would be careful to do this between the pins for Q3 and Q4.
