Trade secrets... How to make a printed circuit board

Printed circuit boards (PCB) are found in almost all electronic devices including mobile phones, iPods, computer motherboards, TVs, calculators, washing machines, radios and car electronics. A PCB is a rugged and effective way of wiring-up electronic components to create electronic devices.

The basic PCB consists of a thin laminate or fibreglass board covered on one side with a thin layer of copper. The copper is etched to form a complex circuit of ‘tracks’ that are used to wire-up and interconnect the electronic components attached to the board. Modern PCBs in mobile phones and computers usually consist of a number of very thin boards sandwiched together to make a complex multilayer PCB.
