P1 Prototyping Boards
One of the most
important things to help you design a project is a board for the
components.
The choice depends on if you want to keep the circuit
as a project or just experiment with the circuit.
At Talking Electronics we have a whole range of boards for different
purposes. We use Breadboards for quick construction, Matrix
Boards for laying out a project so it can be copied to make a
Printed Circuit Board and Surface-Mount Boards for these
wonderfully miniature components.
We have designed Matrix Boards in all shapes and sizes so you can pick a
board to exactly fit a project.
Everything you do should be neat and clean and that's why you
need to have a range of boards so you can pick the most-suitable board.
Do NOT use STRIP BOARD. The strips have to be cut and its sometimes
difficult to place the components exactly where you want them.
Cutting the strips is
very time-consuming and a messy thing to do. They also force you to lay
out the parts according to the strips and this makes the project very
large and messy.
I still have 3 samples of strip-board, sent to me over 30 years ago. I
have never used them.
They are the worst concept ever to be put on the market.
Do NOT use Strip-board. The layout can be much smaller on matrix
board
and if you use matrix board, the layout can be directly converted to a
a Printed Circuit Board layout.
For a quick construction you can choose a breadboard:

Or for a more-permanent construction you can choose a MATRIX BOARD:

This is a UNIVERSAL BOARD containing holes and pads so you can layout the
parts and solder them to create a circuit and join the components with
fine tinned copper wire.
The final result will be
exactly like the layout of a printed circuit board and you can copy the
design and KNOW IT WILL WORK.
Talking Electronics has created a number of matrix
boards of different shapes and sizes so you can build a project that
looks neat an d professional.
There are three different ways you can build a project.
1. Using through-hole components and a board consisting of holes and
lands, the final result will look very similar to a Printed Circuit
Board and the layout can be copied directly to produce a Printed Circuit
Board.
2. Using surface-mount components and a Designer Board consisting of
lands, the components can be soldered to the lands and joined with fine
tinned copper wire or enamelled wire.
3. The project can use a mixture of through-hole components and
surface-mount. This makes the project look very simple as the
surface-mount components are hidden under the board.
Talking Electronics has prototyping boards for all these arrangements
and you can buy a set of boards to cater for all types of layouts.
SELECTING A MATRIX BOARD
If you have some idea of the size
of the board you will need for a project, go to the range of boards
designed by Talking Electronics and pick the most suitable.
These boards make a project look very neat and they are used for all the
projects we design.
Here's an example of a surface-mount project built on Talking
Electronics 24 holes x 50 Matrix board using both surface-mount and
through-hole components. Note the number of connecting wires. It would
be almost impossible to create the circuit if you have to constantly
turn the board over to create the wiring. It is MUCH easier to work on
one side of the board.

The Printed Circuit board is an exact copy of the layout.
The choice of board is up to you. A
breadboard is for a project you wish to take apart while a matrix board
is for a project you wish to keep.
There is also a whole range of Printed Circuit Boards for surface-mount
components.
Some PC boards are called "break-out boards" or "adapter
boards" or "interface
boards" as they simply allow a surface mount chip to connect to another
board containing normal components.
Other boards have a small amount of space for surface-mount components
and others allow surface-mount components to be connected to a
through-hole components and chips. There are all sorts of different
combinations. Some are expensive and some are cheap, but they all make a
project look neat.
SURFACE MOUNT PC BOARDS:
A pack of 5 different surface mount PC boards for prototyping. These are
specially designed to take surface-mount IC's and the surrounding
components are conventional devices.

LilyPad Protoboard $1.50 from

"Bandicoot" Surface-Mount PC Board $9.95 from

No holes - each pad is 0.100 inches x 0.050 inches.
In other words, 10 pads to one inch in one directions and
20 pads per inch in the other. The board is 76 pads x 40 pads. (8cm x
10cm)
A "1206" component is 0.12 inches x 0.060 inches so it can be
placed
"across-wise" taking up 3 pads with room for connections.
