pcb design

Actually there are lot of companies which do not have their PCB layout designer. They usually hire them for a particular project for a month or two or depend on their requirement. so for layout designer that particular company is called client. The designer has to design the board as per the client requirement. Basic requirements for designing a layout for a layout designer are following .. Schematic Diagram - It's a drawing showing all significant components, parts or tasks of a circuit, device, flow process or project by mean of standard project. It  depends on the hardware engineer whether they are giving the hard copy or soft copy of schematic to the layout designer. if it's a soft copy than layout engineer can directly start the work without creating schematic in EDA tool like OrCad , PADS logic etc.. But if the client has provide hard copy of schematic to the layout engineer than the Layout engineer has to draw it using OrCad or any other tool which his client ...

   As electronics moved from vacuum tubes and relays to silicon and integrated circuits, the size and cost of electronic components began to decrease. Electronics became more prevalent in consumer goods, and the pressure to reduce the size and manufacturing costs of electronic products drove manufacturers to look for better solutions.   Thus was born the PCB.        PCB is an acronym for  printed circuit board . It is a board that has lines and pads that connect various points together. In the picture above, there are traces that electrically connect the various connectors and components to each other. A PCB allows signals and power to be routed between physical devices. Solder is the metal that makes the electrical connections between the surface of the PCB and the electronic components. Being metal, solder also serves as a strong mechanical adhesive.   PCBs may be classified in many different ways according to their var...
