PCB Design 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. PCBs have between one and twenty conductive layers laminated together in a sandwich with insulating plastic. Layers may be connected together through drilled holes called vias. Either the holes are electroplated or small rivets are inserted. High-density PCBs have blind vias, which are visible only on one surface, or buried vias, which are visible on neither. Some designs also have quality control patterns to measure soldering and etching processes.
PCB labels are made of chemical resistant polyester. These PCB labels are screen printed on polyester for a long lasting, chemically resistant marking. PCB labels withstand lead-free reflow. These PCB labels consist of a yellow and black striped decal measuring at least 6″ X 6″.
