Printed Circuit Board Manufacturing
نوشته شده توسط : pcbonline

Printed Circuit Board Manufacturing The PCB or the printed circuit board is an essential component of all electronic products. The big cumbersome vacuum tubes are the predecessors of the PCB Rigid flex PCB Board. The smaller and sleeker PCBs use conductive tracks or signal traces made of copper and laminated on a nonconductive material to connect electrically and support mechanically the components of an electronic product.

How Is A PCB Made?

The insulating board in a PCB is made of different types of insulating materials stuck together to make one board. The use of different materials helps to increase the insulating property of the PCB and helps the board to be better grounded. A solder mask usually green, sometimes red, white, black, or blue, is painted over the board for insulation purposes. The PCB can be single, double-sided, or even multi-layered. When they are double or multilayered, plated holes are used to connect the signal traces on the other layers.

Subtractive methods and additive methods are used by PCB manufacturers. The more popular subtractive methods are silk screen printing, photoengraving, and PCB milling. The method used in PCB fabrication depends on whether he is doing mass manufacturing or only making prototypes. The PCB manufacturers must ensure that their product is identical to the circuit diagram. The layout of a PCB is best created with a combination of Autorouter and manual inputs from the design engineer. Those manufactured purely with the Autorouter are often difficult to repair later on when the product is in use. The initial high cost incurred in PCB fabrication in creating the layout is offset by the fact that PCBs lend itself to large volume production. Once the layout is finalized, these PCBs can be manufactured by PCB manufacturers using completely automated techniques. Large scale production of course makes PCBs relatively cost effective and within the reach of the electronic goods manufacturers PCB Prototype Manufacturer. This in turn helps push down the prices of electronic products and makes it within the reach of the common man.

Uses Of PCB

PCB manufacturers use different dielectrics like FR-1, CEM-3, and so on with varying thickness ranging from 1.0 mm onwards. The most popular dielectric used today is of course FR-4. .Products made by PCB manufacturers include heavy copper boards, HDI boards, and resistance boards.. PCB are found in most of the products used in our houses from the humble cell phone to computers and TVS, music systems and the umpteen electronic gadgets that we take for granted. Since there is so much demand for electronic products and therefore for the PCBs, there are a lot of players in PCB fabrication. There is stiff competition among them to provide the best service and quality at the most reasonable prices. PCB fabricators tailor their products to meet the needs of the electronic industry. PCB manufacturers are a major sector of today's electronic industry. The IPC organization controls overall the PCB manufacturers including designing the PCB, manufacture, and quality control.
