Mounting PCB's and Veroboards
An easy and quick way to fasten veroboards or PCB's to a cabinet or case is to use woodscrews and screwcups. Do not over tighten as this can crack the board. (See below).



Wiring
Cable straps, bread ties and string can all be put to good use to keep groups of wire neat and tidy, see below.



If using wire for a front panel that is removable then stranded wire is more flexible than solid core and more resistant to breakages during movement.

Soldering
Soldering components requires an extra pair of hands, you may find a small plastic vice helpful to hold the board steady while you concentrate on soldering.



Soldered joints should be bright and shiny, trim component leads short and flush to the board after soldering.



The distance between tracks on a veroboard is only 0.1 inch. You may find a magnifying glass helpful to check for shorts between tracks, or test with a multimeter on the ohms range. I have wrote a complete article on how to produce a veroboard layout from a schematic, click this link.

Order of Components
When building a circuit either on PCB or veroboard layout, some com ponenets are more sensitive to heat from your soldering iron. It is therefore better to insert components starting, with wire links, IC sockets and any connectors first. Then follow with passive components, resistors, capacitors, inductors. Finally insert and wire up diodes, semiconductors and IC's. If you have used an IC socket then insert the IC last, observe handling precautions as some componets can be damaged by static discharge.
