IV-3 VFD shield for Arduino

5 Assembly

In the following pages we are going to assemble the PCB step by step. It may be helpful

to keep the PCB overview and the circuit diagram at hand during assembly.

After every step, carefully compare your PCB with the pictures in the manual and check

for errors and solder faults.

Diodes and IC socket

Mount the following diodes:

D1: 1N400x or equivalent

•

D2...D5: 1N5819 schottky

•

diode

Watch the polarity and be careful

to mount the right diode in the

right place.

Solder

and

component

side

wires on the solder side as short

as possible as they are positioned

above the metal USB connector

shielding of the arduino.

Mount the 8 pole IC socket for IC1. Do not place IC1 in the socket at this stage.

Electrolytic capacitors

Mount the following electrolytic

capacitors:

C5...C8: 22µF 50V radial

•

electrolytic capacitor

C9, C10: 100µF 25V radial

•

capacitor

Bend the leads 90 degrees and

mount the capacitors flush to the

PCB. Watch the polarity.

It is recommended to solder C6,

C7 and C8 from the component

side and to trim the leads as short

as possible on the solder side as

they are positioned above the metal shield of the Arduino USB connector.
