The SB400 Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout. The SB400 has the same pattern and spacing as a standard 400 connection point BB400 solderless plug-in breadboard. It has a standard 5-hole strip for each IC pin, just like solderless breadboards plus 4 power rails. However, it has the advantage that soldered joints provide a more reliable long-term connection than solderless contacts. The SB400 has four power rails like solderless breadboards, plus two bonus rails for power or signals. There are bonus two-hole pads along the centerline allowing DIL (dual in-line) headers to be used. BPS prototyping boards use high-quality FR4 glass epoxy PCBs for long life, with an anti-tarnish protective coating for easy soldering. BPS boards are lead-free and RoHS compatible.
