A printed circuit board (1960s) with diodes, resistors, capacitors and transistors. The board is possibly a spare for an unidentified computer or machine.

A printed circuit board has electronic components that are connected using conductive pathways. Thin copper sheets are bonded onto a support base and then etched to create the conductive pathways between the electronic components. Holes are drilled in the board and the components are soldered into place along the pathways.

Physical Description

The board is a rectangular shape made of a brown plastic coated material. One side has silver or gold-coloured metal patterns. The other side has electronic components such as transistors, diodes, resistors and capacitors. There is text and numbers printed in white ink near the various components on the board.
