PCB Information: What is PCB?
http://pcbinfo.blogspot.com/2005/05/what-is-pcb.html
Friday, May 06, 2005. A printed circuit board or PCB interconnects electronic components without discrete wires. Alternative names are printed wiring board or PWB. A printed circuit board consists of "printed wires" attached to a sheet of insulator. The conductive "printed wires" are called "traces". The insulator is called the substrate, and is made of "Pertinax" (a phenol formaldehyde resin) or a fiberglass-reinforced epoxy composite material. 2 PCB Milling, the use of a 2 or 3 axis mechanical milling ...

PCB Information: How PCB is manufactured
http://pcbinfo.blogspot.com/2005/04/how-pcb-is-manufactured.html
Thursday, April 07, 2005. How PCB is manufactured. Printed Circuit Board (PCB) are manufactured through a series of phot imaging and etching processes. For a start we need a schematic of the circuit to be created in a CAD software, from this schematic a "Gerber Data file is created and then is converted via computer aided manufacturing software (CAM) to form the basic layout of the Printed Circuit board itself. The etched layers are then laminated together by pressing them with thin sheets of resin coate...
