Q:Pcb board on the big black dot chip package called what?
As the printed circuit board is not a general terminal product, so the name of the definition of a little confusion, such as: personal computer motherboard, called the motherboard, and can not be directly called the circuit board, although the motherboard board there is a circuit board, but Is not the same, so the assessment of the industry when the two can not say the same.
Q:What is the printed circuit board circuit
(Such as element holes, fastening holes, metallized holes, etc.), instead of the chassis of the conventional electronic components, and to realize the interconnection between the electronic components. Because this board is made using electronic printing, it is called "printed" circuit board.
Q:General computer PCB board can withstand the number of temperature?
According to the number of circuit board can be divided into single-sided, double-sided, four-tier, six-board and other multi-layer circuit boards.
Q:PCB circuit board has several materials?
It is reinforced with a material (Reinforeing Material), impregnated with resin adhesive, through drying, cutting, laminated into a blank, and then covered with copper foil,
Q:Who can tell me printed circuit board in the multi-layer and double-sided panels and the difference between the single-layer, multi-layer between the layers is how the distribution?
Multi-layer wiring layer, between the two layers is the dielectric layer, the dielectric layer can be done on the multi-layer circuit board at least three layers of conductive layer, two layers in the outer surface, and the remaining layer is synthesized in the insulation board
Q:What does the motherboard PCB mean?
PCB, PrintedCircuitBoard, the Chinese name for the printed circuit board, also known as printed circuit boards, printed circuit boards, is an important electronic components, is the support of electronic components, electronic components is the electrical connection provider.
Q:What is the classification of circuit boards
According to the different classification methods can be divided into many kinds: For example, according to the strength of the substrate points: soft board hard and soft combination version according to the structure: through-hole plate buried blind hole in accordance with the color points: green oil plate, red oil plate, white oil
Q:Double-sided circuit board, what is the hole ah
The buried hole refers to the connection hole located in the inner layer of the printed circuit board and does not extend to the surface of the circuit board.
Q:How to eliminate the protection of IC on the circuit board paint
The circuit board mainly consists of pad, through hole, mounting hole, wire, components, connectors, filling, electrical boundary and so on. Common board structure includes single layer PCB (single Layer PCB), double board (Double Layer PCB) and multi-layer board (Multi Layer PCB) three.
Q:Protel how to lock all components
In the electronics industry CAD software, it deservedly ranked in front of many EDA software, is the preferred software for electronic designers, it began to use in the country earlier, the highest penetration rate in the country, and some colleges and universities of electronic professional also Special courses to learn it, almost all of the electronics companies have to use it, many large companies in the recruitment of electronic design talent in their conditions on the bar often asked to use PROTEL. Early PROTEL mainly used as a printed circuit board automatic routing tools,
