BreadBoard Quality Criteria:

• insertion force for 0.025" square post headers
• removal force for 0.025" square post headers
• good conductivity with 26 AWG wire (even after square post insertions)
• consistency, do all contacts on the breadboard work equally well
• consistency, does each batch from the factory work equally well (even months or years apart)

To determine the quality of a solderless breadboard, a common test is to evaluate how well it works with square post headers. We have experienced breadboards where wires cannot be inserted or removed from the square post headers on a breadboard. We know how frustrating this can be when you just want the breadboard to work.

A good quality breadboard works well with thin and thick conductors and has a long contact life. Good quality breadboards will be usable with fine 26 AWG wires and large 0.025" square post headers. Quality testing is performed on all of our breadboards by inserting a smooth 0.025" post 50,000 times by machine and measuring the contact resistance. Quality contacts with the correct metal composition (phosphor bronze with plated nickel finish) will spring back, providing good contact force and conductivity, even after a large number of insertions.

Kit manufacturer customers switch to using BusBoard BB830 BreadBoards in their kits because they work reliably with square post headers. One customer tested 15 different brands of solderless breadboards to find one to include with his development board kits. They found that only two of the 15 brands could reliably use square post headers. They immediately implemented the BB830 in their kits due to the consistent quality and dependability found in our BreadBoards.
