Do beef up high current traces with solder.
Don’t use solid wire to connect to devices off the Vero
Do run a small slot blade screw driver between traces
to remove hair size shorts after building.
Don’t bridge two pins or traces with solder; always use
a wire jumper on the component side.
Do take out one “hole width” when creating an open.
Don’t jam too many parts on a small board; estimate
your real estate beforehand.
Do use “back EMF” diodes on all relay coils and
Don’t make short wires to panel mounted devices;
supply enough length to access the Vero board
Do attempt to align all the ICs in the same orientation.
Don’t mark up your board with felt pen to highlight
power buses; use proper wire colors instead.
Do create loops of solid wire to monitor power and
Don’t use an old board with tarnished copper; brighten
copper with fine sandpaper.
Do use IDCs for LEDs, logic level signals, pushbuttons,
Don’t use IDCs for power, critical measurements, and
high current devices; use screw terminals.
Do create both pictorial and schematic diagrams for
servicing your Vero project.
Don’t desolder with a dry tip; use a wet tip when using
Do fuse your power on or off board; poly switches can
be used, as well.
Don’t use leaf IC sockets; use machine sockets only.
Do breadboard the circuit first to plan for space and
Don’t solder wires or components on the
would add an ICSP (In-Circuit Serial Programming) five-pin
IDC header for downloading source code. All of my
PIC16F877A-04 based PCB (printed circuit board) projects
have this feature which is connected to a DB9 connector
on the chassis of the project.
ThaT’s a Wrap
There are many opinions about when, where, or if to
use Vero vs. designing a PCB. The majority of negative
experiences involving strip board use originate from the
lack of skill creating the strip board circuit. If built properly,
a Vero board design can be just as reliable when
compared to a PCB.
It is important to follow the guidelines presented here,
however, being flexible and adapting to new situations is
important too. This may require ignoring a rule or practice
to build the best possible Vero board circuit. NV
