Befaco PERCALL V1 Assembly Manual

Advertisement

Quick Links

THANKS FOR CHOOSING ONE OF OUR KITS!
This manual has been written taking into account the common issues that we often find people experience in our
workshops. The order in which the components are placed on the board is meant to make assembly as easy as possible.
Some steps are not obvious, so even if you're an experienced DIYer please read the steps thoroughly before starting.
If this is your first project, please read this article before you start assembling the kit:
www.befaco.org/howto/
You will be soldering both boards at the same time. Keeping them in the panel together might help you through the build.
Check last pages of the Build for PCB pics to help you identify components.
HAVE FUN!

  • Page 1 Some steps are not obvious, so even if you're an experienced DIYer please read the steps thoroughly before starting. If this is your first project, please read this article before you start assembling the kit: www.befaco.org/howto/ You will be soldering both boards at the same time. Keeping them in the panel together might help you through the build.
  • Page 2 DIODES Solder the diodes observing their polarity. The black or white line on the diode must match with the white line on the diode symbol on the PCB silkscreen. Value Name on PCB 11 1N4148 D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11 1N5817 (black) D12, D13 FERRITE...
  • Page 3: Power Connector

    ELECTROLYTIC CAPACITORS Values are written on the side of the capacitor. Mind their polarity (The long leg of the capacitor is the positive (+)). Value Code Name on PCB 10uF 10uF C21, C22, C23, C24, C31, C32 TRANSISTORS Be sure they are orientated correctly. The curved and flat sides of the silkscreen outline of the transistor on the PCB must match that of the transistor’s body.
  • Page 4 FEMALE PIN HEADERS Place the female pin headers on the control board over the silkscreen markings at positions and solder. Double check they all are perfectly straight. PINs Name on PCB SV101, SV102 SV100 Now it’s a good moment to split the boards apart. SPACER Secure the spacer onto the CONTROL PCB (through the two hole with silver outline) with the main body of the spacer on the component side, and the nut on the opposite.

    POTENTIOMETERS Now place the potentiometer on the PCB but... don't solder them yet! Type Name on PCB Single (3pin) B100k VOL1, VOL2, VOL3, VOL4 SWITCHES Place the switches in their right places. don't solder them yet! Type Name on PCB Mini.
