LABC1 BATTERY CHARGER KIT ASSEMBLY

Although we know that you are anxious to complete the assembly of your battery charger kit it is best to follow the step-by-step instructions. Try to avoid the urge to jump ahead installing components.

Since you may appreciate some warm-up soldering practice as well as a chance to put some landmarks on the PC board, we’ll first install a couple of the larger components. This will also help us to get acquainted with the up- down, left-right orientation of the circuit board. Remember that the components will be mounted on the component side of the circuit board and soldered on the solder side of the circuit board, the side that contains the printed circuit traces. Have a look at the parts layout diagram to help with your assembly.

Use the boxes to check off your progress.

Check all received parts against the parts list. The parts list describes the various markings that may be found on the kit parts. Carefully sort the parts into small piles, (an empty egg tray does nicely for this purpose) to aid in finding the correct part at the required time.

ˆ1. Install DPDT PC mount pushbutton switch, S1. Be sure it is seated properly before soldering all 6 pins.

ˆ2. Install J1, the 2.1mm power jack.

We’ll begin to install some of the polarity sensitive parts at this point. Use the parts layout diagram in addition to the PC board silkscreen to orient the diodes, electrolytic capacitors, transistors and ICs properly.

ˆ3. Install D1, 1N4002 diode (black with white band). You’ll see a black band on the PC board silkscreen. Line up the white band on the diode with this black band. This is the cathode side of the diode.

ˆ4. Install D2, D3 and D4, 1N4002 diodes (black with white band) in the same manner as you did D1 above. Carefully orient the banded end before soldering these diodes.
