A: Due to large stray capacitance (from 2-25pF per contact point), the inductance of connections, and a relatively high and not very reproducible contact resistance, solderless breadboards are limited to operate at relatively low frequencies, usually less than 10 MHz, depending on the nature of the circuit. The relatively high contact resistance can also be a problem for some DC and very low frequency circuits. Source http://en.wikipedia.org/wiki/Breadboard Higher frequency operation may be possible in some cases, depending upon the circuit requirements. Note: Solderable PC BreadBoards, such as the BPS BR1, SB300, and SB400 will provide lower stray capacitance and lower connection resistance which may allow higher frequency operation for some circuits. For circuits sensitive to small changes in values, component adjustments may be needed when the circuit is moved from a plug-in breadboard to a Solderable PC BreadBoard, due to these small differences. Q: Can I plug DIL or SIL connector headers into the breadboard? A: Yes. The square pin of a standard 0.1" spacing header is typically 0.025 inches wide. This is within the 0.016 to 0.028 inch wire insertion size range recommended for the breadboard.

A: US Patent #203938 was awarded to Ronald J. Portugal of EI Instruments Inc. in 1971. Q: Why is phosphorus added to the bronze used in the contacts? A: Phosphor bronze is an alloy of copper with 3.5 to 10% of tin and a significant phosphorus content of up to 1%. The phosphorus is added as deoxidizing agent during melting. These alloys are notable for their toughness, strength, low coefficient of friction, and fine grain. The phosphorus also improves the fluidity of the molten metal and thereby improves the castability, and improves mechanical properties by cleaning up the grain boundaries.
