ASSEMBLE COMPONENTS TO PC BOARD
Figure A
Diodes have polarity. Be sure
that the band is in the correct
direction.
Figure B
Electrolytics have a
polarity marking
indicating the (–)
lead. The PC
board is marked to
show the lead
position.
Warning: If the capacitor is connected with
incorrect polarity it may heat up and either leak
or cause the capacitor to explode.
Figure C
Mount the transistor with the
flat side as shown on the top
legend. Leave 1/4” between
the part and PC board.
