Transient Voltage Suppressors (TVS) avalanche diodes and diode arrays can be used to protect sensitive electronic components from the surge pulses that arise from ESD and EMI.

Printed circuit board (PCB) is a component made of one or more layers of insulating material with electrical conductors.

I have collected a lot of material and soon it will begin a tutorial on the realisation about printed circuits.

"A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. from Wikipedia Printed Circuit Board

There are plenty of sites on the web about PCB design, manufacture, application, reliability and companies.

Some videos about technology used for PCBs

If your are new or experienced PCB manufacturer you might find that using a reference design saves you time and money over trying to start from scrath with a new design yourself.

List of pcb magazines

There are two basic technologies associated with PCB fabrication: design and manufacture.

From basic physics it is known that currents circulating through materials dissipate some energy as heat.
