An insight into Printed Circuit Boards
Printed circuit boards (PCBs) are thin boards made from an insulating material, with a metal coated surface, sometimes on both the top and bottom. It is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. Etches are made in the metal with acid to create pathways for electricity to travel among various components which are surface mounted on the board with solder.
The invention of PCB prototypes in USA is one of the factors that has enabled electronic circuits to be smaller, more compact, and contained on a convenient, rugged board. A PCB is a think board in which electrical components are connected using copper tracks instead of wires. Holes drilled in the bare boards in USA are used to fix the electrical components in position. They are then soldered to secure them in position and the copper tracks link them together forming a circuit. The board and the components together are known as a PCB Assembly. (Or Printed Circuit Board Assembly) These days once the design process has been carried out using computer aided design (CAD) and a plan is formed the manufacture of PCBs can be fast as it is automated through machinery and computer technology. The next part is the testing and quality control element of the process.
Today, just about every electronic appliance in your home contains a printed circuit board of some type: computers, printers, televisions, stereos, musical instrument amplifiers and synthesizers, digital clocks, microwave ovens, telephone answering machines and even cell phones. Conducting layers are typically made of thin copper foil. Insulating layers dielectrics are typically laminated together with epoxy resin prepreg. The board is typically coated with a solder mask that is green in color. Other colors that are normally available are blue, black, white and red. There are quite a few different dielectrics that can be chosen to provide different insulating values depending on the requirements of the circuit. Synergisepcb.com are a prominent manufacturer, supplier and exporter of specialized high precision, high density, high reliability PCB prototypes in USA. It was established in 2002 with a firm commitment to match the international standards in the designing and manufacturing of PCBs. They have achieved many milestones in their area of activity of CAD designing services, circuit design services, printed circuit board design services, printed circuit board manufacturing services, printed circuit board layout services.
