Description

This large universal double-sided prototyping board is 20 x 30 cm (7.8 x 11.8″) in size with standard hole pattern on 2.54mm (0.1″) centers.

PACKAGE INCLUDES:
  • PCB, 20 x 30 cm Universal Prototype Board
KEY FEATURES OF PCB 20 x 30 CM UNIVERSAL PROTOTYPE BOARD:
  • 20 x 30 cm (7.8 x 11.8″) outside dimensions
  • 1.6mm (0.64″) thickness
  • FR-4 double-sided construction with green solder mask
  • Holes on 2.54mm (0.1″) centers in grid pattern with alphanumeric grid marked along edges of the board.
  • Holes are plated through with same pad pattern on both sides of the board.
  • Edge solder pads are on 5.08mm (0.2″) centers
  • HASL (SnPb) plating over copper for best solderability

These boards are useful for permanently mounting components and wires via soldering when a project is put into permanent use.

Some circuits with high energy or high frequency such as DC-DC converters or high power MOSFETs need to be prototyped on boards of this type rather than using solderless breadboards since the components need to be placed closely together with robust connections that can handle heavy current transients.
