Pololu - Adafruit Perma-Proto Half-Sized Breadboard PCB (3-Pack)

These half-sized perma-proto boards from Adafruit function similarly to standard perf-boards in that through-hole parts must be soldered to the board, but the holes are internally connected like on a 420-point breadboard, with four bus lines that each span the length of the board and 30 rows of electrically connected pins. They also feature a labeled silkscreen and mounting holes, which make it easy to transfer your prototype to a permanent circuit board and project box. These boards are sold in packs of three.

Key Features: Single PCB breadboard 60 rows of double 5 hole rows Big 1.2mm through plated drill holes Gold plated finish This proto-board is the PCB you always wish you had, but never realized it! Adafruit took the basic layout of a full-sized breadboard (the PCB has 60 rows instead of 63 rows) and turned that into a beautiful PCB. The top side has a white silkscreen, and the same markings you're familiar with, to make transferring components easy.
