A PC Board 14x20 typically refers to a small universal prototyping circuit board (perfboard) featuring a matrix of 14 by 20 holes, giving you 280 individual solder points. These compact boards measure approximately 4 x 6 cm and are used for DIY electronics and testing circuits.

Hole Matrix: 14 rows by 20 columns (280 holes total)
Physical Dimensions: Roughly 40 x 60 mm (4 x 6 cm)
Hole Pitch: Standard 2.54 mm (0.1 inch) spacing
Material: FR-4 glass fiber, usually double-sided with pre-tinned pads
Thickness: Standard 1.6 mm
