All electronics, whether it be mobile smart phones or next generation computer systems have what is known as a printed circuit board. PCB for short, this is designed to support and connect electronic components inside the hardware. The conductive pathways found on the printed circuit board is wired together through the use of soldering. The soldering attaches metal, generally lead, gold or copper, between the different circuit boards in order to properly connect all equipment together inside the device. Inferior connections result in a loss of signal, poor circuit transfers and possible breakage. When it comes to PCB assembly, having impeccable soldering is essential, in order to establish and produce equipment with longevity.
