Building a printed circuit board.

To create a printed circuit board pcb you need to draw holes pads and wires for your circuit. 1 square foot 1 34 mils thick. A printed circuit board pcb mechanically supports and electrically connects electronic components using conductive tracks pads and other features etched from copper sheets laminated onto a non conductive substrate. This typically requires soldering very fine wire often 30 or 40 gauge wire under a microscope to very small test points on pcb before real testing can take place which can be very tedious and time consuming.

The ink serves as the protective layer to cover the copper part that shouldn t be etched. These are used in almost all computers and electronics today. The printed circuit board is built by alternating layers of conductive copper with layers of nonconductive insulation material. In other words one ounce of copper will cover one square foot when it is rolled out to a thickness of 0 00134 or 1 34 mils.

After you had printed your circuit board design you will iron the printed design over the copper side of the pcb ironing it above the copper side of the board will transfer the ink from the glossy paper to the pcb board. The copper foil used in circuit boards is typically in sheets of oz. Per square foot in weight or 0 0007 and 0 00134 inches nominal thickness. Make sure the print is on a glossy paper like those in magazines or separate glossy paper.

Print the design out from the software s print menu. During manufacture the inner copper layers are etched leaving intended traces of copper to connect circuit components. When you re done send the design to a manufacturer or you etch it yourself. A printed circuit board pcb mechanically supports and electrically connects electronic components using conductive tracks pads and other features etched from copper sheets.

This skill is called pcb design and is highly useful. The pre defined tracks reduce the wiring thereby. Carefully cut out the design and position it on the circuit board. A printed circuit board has pre designed copper tracks on a conducting sheet.

A printed circuit board pcb is a plastic board made for connecting electronic components together.
