Q:What is the classification of circuit boards
Double panel is an extension of a single panel, when the single-layer wiring can not meet the needs of electronic products, we must use the double-sided. Sided copper with a trace, and can pass through the hole between the two lines between the lines, so that the formation of the required network connection.
Q:Circuit board A what it means
So that the circuit mini, visualization, for the fixed circuit of mass production and optimization of electrical appliances play an important role.
Q:What does the motherboard PCB mean?
Now the motherboard and graphics cards are used multilayer, greatly increased the area can be wiring. Multilayer board with more single or double-sided wiring board, and in each layer between the layers into a layer of insulation after the pressure
Q:Multilayer circuit boards, is not all power must be placed on the inner layer
Double panel is the middle layer of media, both sides are the line layer. Multilayer board is a multi-layer wiring layer, between the two layers is the dielectric layer, the dielectric layer can be done very thin. The multilayer circuit board has at least three conductive layers, two of which are on the outer surface, 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.
Q:Which boards are difficult boards?
Printed circuit boards and semi-flexible printed circuit boards. Which HDI, rigid-flex relatively difficult. Because of its complex process, the process, equipment requirements are high.
Q:Circuit board how to see the line
Above is an example of ordinary CRT TV, but now the LCD LCD / PDP plasma TV most of the line principle and ordinary CRT TV is different, which requires you to see some of this book. Player, line principle and the above products are completely different, if you want to understand MP3, you have to see some of this book.
Q:Multi-layer circuit boards and single-layer circuit board how to distinguish
Comparison of the most common, the most simple way to distinguish, pick up the light, the inner core is opaque, that is, all are black, is the multi-layer board, and vice versa is a single double panel, and single
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:Protel pcb how to rotate the board?
PROTEL is Altium's EDA software, which was introduced in the late 1980s, and is well-deserved in front of many EDA software in the CAD software of the electronics industry. It is the preferred software for electronic designers.
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.
