Q:What is the working principle of the circuit board?: the circuit board to make the circuit mini, visualization, for the fixed circuit production and optimization of electrical appliances play an important role in the layout. The circuit board can be called printed circuit board or printed circuit board, the English name is (Printed Circuit Board) PCB.

Q:Multi-layer circuit boards and single-layer circuit board how to distinguish: Panel, only a layer of lines, there is no copper inside the hole. Double-sided is the front and back are lines, lead through the hole there are copper.

Q:What is the printed circuit board circuit: Printed circuit board it has two functions: 1, fixed components; 2, according to the circuit diagram with the wire to connect the components to form a solid circuit.

Q:What does the printed motherboard mean?: Its development has been 100 years of history; its design is mainly layout design; the main advantage of using the circuit board is to greatly reduce the wiring and assembly errors, improve the level of automation and production labor rate.

Q:Protel how to lock all components: fully installed more than 200 M, it works in the WINDOWS95 environment , Is a complete board-level all-round electronic design system, which contains the circuit schematic drawing, analog and digital circuit mixed signal simulation, multi-layer printed circuit board design (including printed circuit board automatic routing), programmable logic devices Design, chart generation, spreadsheet generation, support for macro operations, and client / server (client / server) architecture,

Q:PCB (double-sided multi-layer printed circuit board) about the production principle of what?: (Cut through the production unit) -> drilling (drilling through hole) -> copper (copper on the hole, the principle is the palladium ion) -> plate power (thickening table / hole copper thick) ->

Q:PCB board in the multi-layer is what it means: and the remaining layer is integrated in the insulating plate. The electrical connection between them is usually achieved by plating through holes in the cross section of the circuit board. Unless otherwise stated, multilayer printed circuit boards and double-sided panels are generally plated through-orifice plates.

Q:Pcb board on the big black dot chip package called what?: Printed circuit board {PCB circuit board}, also known as printed circuit board, is the electronic components of the electrical connection provider.

Q:What is the multilayer circuit board: In the formation of layers through the hole after the formation of metal copper layer on its need to complete the inter-layer circuit conduction. First with a heavy brush and high pressure flushing the way to clean up the holes on the hole and the hole in the dust, and then to potassium permanganate solution to remove the hole on the copper surface of the glue residue. In the clean hole on the wall soaked with tin palladium paste layer, and then reduced to metal palladium.

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
