Breadboards, issues, quality, the hunt for well made

Catwell

Over the course of many years of engineering I have used countless solderless breadboards. And through this time I have noticed that many of my projects refused to work when using certain ones, or isolated areas on a second, or the values of my components changed while using a third. It seems that the quality is pretty hit or miss. I once spend a weekend trying to make a circuit work on one board before having the same circuit work flawlessly on another.


Since I am not sure of the build quality of any breadboard, I've turned to you, the community, for help in this area. What is the best, highest quality, and rugged breadboard available?


Also, while we are on this subject, I am also looking for a high amperage breadboard. I have melted a few in the past.

  • There's such a large range of solderless breadboards these days and the quality varies greatly even with in the same brand.

    If you tear down a solderless breadboard you'll find that the conductors are merely bulldog clip style shaped u channels.

    The grabbing force of each hole can be influenced by the wires or component pins inserted on neighbouring holes that are on the same clip.

    Leads from some components like small signal diodes and 0.125W resistors are too narrow for a reliable connection. Other components have pins that are too short such as some DIP switches.

     

    Some of the cheaper brands of breadboards don't even have the u channel bus bars inserted correctly so that when a wire is inserted it won't be between the two contacts but askew to one side.

     

    I've found that the optimal wire diameter is between 0.70mm to 22 AWG. It's the diameter of the precut breadboard wires.

    E14 sell them https://au.element14.com/search?st=923345  but they're not cheap.

    Once a design has been proven it can then be transferred to a PCB.
