solderless bread board question

[Michael Eisenstadt]

Is a solderless bread board just as good as
bread boards which require soldering?

I have assembled the components for a project
but as I have never done this before, I need
to ask some basic questions.

Thanks in advance for your help.

It is fine for prototyping, but not a good idea for a permanent project. The
connectors can work loose easily over time. Usually you will test the
circuit on a breadboard to ensure it meets your specifications, then
transfer it to a solderable breadboard for permanence, or lay out your own
circuit board.

They are not make as low resistance connections as solder, and are
limited to about an ampere and get lose and degrade after a lot of
use. They also have more capacitance between adjacent strips and to
the grounded back plate than you will have with a soldered board.
But, with a bit of care, you can do quite a lot with them.

I have breadboarded a 40 pin PIC microprocessor system that took up
about 100 square inches of PC board area when it was laid out, and the
breadboard worked just fine. They are a good introduction to noise
coupling and supply drop.

Do you have any other specific questions?

Hi, Mike. Like most practical technical issues, "it depends". I feel
comfortable using them for circuits where you aren't too concerned about small
capacitances between connections, and you're not running over 1 amp through any
connection. Also, the contacts themselves can be somewhat resistive,
especially if you're in the habit of running current too high, or weaken the
clips underneath by trying to fit heavy gauge wires into the connectors. It's
usually best to stick with 22AWG or 24AWG wire whenever you can. Also, the
"ground plane" underneath the breadboard isn't very effective for high
frequency work.

In short, keep your highest frequency of interest below a couple of MHz, don't
use it for circuits where several pF of capacitance between pins is a problem,
keep the currents low, and use moderate gauge wire. Even when you're using
these boards, wire layout can be important. Solderless breadboards can save a
lot of time, and can be really convenient.

Good luck
Chris


Be very aware

what does 22AWG mean. What do the A/W/G stand for. I heard
people mention these things when needing to constuct an fm coil

thanks
