Take precautions with regard to electrostatic discharge (ESD) safety. Handling components should be done
in electrostatically safe environment. Use personal and workplace grounding. Any discharge (even a minor
one) from body to a component may permanently damage it.
Our PCBs have silkscreened both component values and designators, but as resistors are mounted vertically,
we highly recommend you to print out files with component placement before you start assembly of the
module. And, please, at least take a look on this manual!
Some components are marked as NU (not used) – leave those unpopulated! Some components are
market as OPTION (those are for optional modifications) – leave those unpopulated for now.
ASSEMBLY
1
Solder horizontally placed resistors, diodes and
ferrite beads! Pay attention on orientation of
diodes! Also, solder IC sockets!
GUIDE TO ASSEMBLY OF ERICA SYNTHS DELAY MODULE
2
Solder ceramic capacitors!
3
Solder vertically placed resistors! Here it’s critically
important to follow part placement as resistor
density is quite high.
4
Solder electrolytic capacitors, transistors, voltage
reference, resettable fuses and an optocoupler! Pay
attention on correct orientation of the components!
Negative lug of the
electrolytic
capacitor is marked
with a stripe!
