God’s Box – Loose Fruit 

Eurorack DIY Kit 

Instructions 

Version 1.1 

 

  

 

SOLDER JOINTS 
 

Your solder joints should look like those shown as ‘OK’ below, they should 
have that neat conical shape on 

BOTH sides of the PCB

. If they don’t look 

the same on both sides then stop! Work out why from the soldering guides 
linked and don’t continue until you are getting those results.  
 
This isn’t just OCD talking, you are very likely to end up with a destroyed, 
damaged or defective unit if you’re not hitting that standard.
