ADDAC305 Assembly Guide STEP 1: Locate Pcb and surface mount parts. STEP 2: Start by adding a bit of solder to every smd part right pads, this will make it easier to solder the surface mount parts. If you’re left handed then add solder to the left pads.

ADDAC305 Assembly Guide STEP 3: Now let’s place all 8 of the 1k resistors, use a tweezer and solder the right pad of each by heating the already added solder and place the part in place. STEP 4: Next solder the right pad for all four 100nF capacitors.

ADDAC305 Assembly Guide STEP 11: Locate the jacks and cut the smallest legs like shown below. We’ll now populate all front panel parts: DO NOT SOLDER ANY PART UNTIL ALL PARTS ARE PLACED! STEP 12: Locate and place, do not solder, the 3 jacks with threaded shaft at the bottom.

ADDAC305 Assembly Guide STEP 14: Next let’s place latch buttons, note that the buttons have polarity because of the leds inside, longer leg is the positive (+) side. The bottom of the button also shows + & - markings to show the polarity.

ADDAC305 Assembly Guide We’ll now describe s a good practice that minimizes any damage that may occur to all front panel parts for continued exposure to the soldering iron heat. It happens often that users not very used to soldering spend too much time on each pad.

ADDAC305 Assembly Guide STEP 17: After all parts are placed we’ll now solder all pads. Follow the process described in the previous page. STEP 18: Once finished it will look like this. Congratulations, you’re done! ADDAC SYSTEM page 11...
