P-PC-SB404 BreadBoard - Solderable PCB, 400 point pattern
Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout. This breadboard has the same pattern as a standard 400 connection point solderless plug-in breadboard which has a standard 5-hole strip for each IC pin, just like solderless breadboards. However, it has the advantage that soldered joints provide a more reliable long-term connection than solderless contacts.
The board 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 as well as a top side silkscreen to position components. Four mounting holes allow your projects to be secured.

Strips can be cut as needed to make smaller tracks and circuit pads and the board has 0.1" hole spacing for DIP integrated circuits/ headers as well as other parts. Higher quality than traditional stripboard, the holes are drilled, not punched.
