History of PCB Used in PC
Prior to the invention of the microprocessor PCB, a computer consisted of multiple printed circuit boards in a card-cage case with components connected by a backplane, a set of interconnected sockets. In very old designs the wires were discrete connections between card connector pins, but printed cir...
Take a Fast Look at PCB Electronic Parts
A printed circuit board or PCB, is a plate or pcb board used for placing the different elements that conform an electrical circuit that contains the electrical interconnections between them. The most simple printed circuit boards are the ones that contains copper tracks or interconnects pcb board on...
PCB Component Packages
Today in the market you can pcb board find a great variety of electronic component packages. It is common to find several types of packages for one device. For example you can find the same pcb board integrated circuit in QFP's and LCC's packages. Thru-Hole Are all those components that have pins ...
The Most Common PCB Components
1. Terminals PCB and Connectors: Components to make electrical connection. 2. Resistors: Components used to resist current PCB. 3. Switches: Components that may be made to either conduct (closed) or not (open). 4. Capacitors: Components PCB that store electrical charge in an electrical field. 5. ...
How to Pick the Right Motherboard
Motherboards are the most complex PCB component in your computer. Fitted with hundreds of components and dozens of options it can be difficult to choose. PCB Let’s look at the most important factors to help you decide before building your next computer. Motherboards are the central nervous system ...
Take a Quick Look at PC PCB(overview)
A printed circuit board (PCB) in PC is also called motherboard. A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board, or colloquially, amobo) is the main printed circuit board (PCB) found in computers and other expandable systems. It holds many of t...
SMT PCB Assembly
Where components are to be placed, the printed circuit board normally has flat, usually tin-lead, silver, or gold plated copper pads without holes, called solder pads. Solder paste, a sticky mixture of flux and tiny solder particles, is first applied to all the solder pads with a stainless steel or n...
Disadvantages of SMT PCB
Manual prototype assembly or component-level repair is more difficult and requires skilled operators and more expensive tools, due to the small sizes and lead spacings of many SMDs. SMDs cannot be used directly with plug-in breadboards (a quick snap-and-play prototyping tool), requiring either a cus...
Advantages of SMT PCB
The main advantages of SMT over the older through-hole technique are: Smaller components. As of 2012 smallest was 0.4 × 0.2 mm (0.016 × 0.008 in: 01005). Expected to sample in 2013 are 0.25 × 0.125 mm (0.010 × 0.005 in, size not yet standardized) Much higher component density (components per un...
Take a First Look at SMT PCB
Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). Surface-mount technology was developed in the 1960s and became widely used in the late 1980s. Much of the pioneering...
