Dual Mini Synthesizer Build Instructions

Make sure you have everything before you start soldering!

1

Install Diode

What You’ll Need:

To make assembly easier, we’re going to install components from shortest to 
tallest. This way when you flip the board over to solder them, your work 
surface will hold them in place.  Let’s start with the diode.

To prep the leads, hold the body of the diode and bend the two leads 90 
degrees.

Insert the diode into the holes marked D9 on the main PCB.  

Polarity does 

matter for diodes

, so when you insert it into the board, make sure the black 

stripe on the diode lines up with the stripe on the silkscreen pattern.

Bend the leads outward underneath the board to  hold the diode in place.

Flip the board over, solder the diode leads, then trim them just above the 
solder joint.

Install Resistors

Working one value at a time, prep the leads of the resistors like you did with 
the diode.  

Insert the resistors into their proper locations (see BOM).  Polarity doesn’t 
matter for resistors, but your board will look neater if you line up all the 
tolerance bands (gold) the same direction.  Bend the leads outward 
underneath the board to hold the resistors in place.

Flip the board over, solder the resistor leads, then trim them just above the 
solder joint.

Install Ceramic Capacitors

Install and solder C3-C6.  Polarity doesn’t matter for these capacitors.

Install IC Sockets

Insert the IC sockets into the board.  Note that one end of each socket has a 
notch in it to indicate which end of the IC has pin 1.  Make sure to align these 
notches with the notches indicated on the silk screen pattern.

Flip the board over and solder one pin on each corner of both sockets.  This 
makes it easy to reposition the sockets in case they aren’t seated all the way 
down against the board; just reheat the corner pins and adjust the socket 
positions as necessary. 

Once you are happy with the positioning of the sockets, solder the remaining 
pins.  The pins are short enough that they don’t need to be trimmed.
