Q:What is the multilayer circuit board
In the line image transfer printing as the inner line, but in the circuit etching is divided into positive and negative two production methods. Negative film production methods as the inner line of production, in the development of copper directly after the film to complete the film
Q:Circuit board how to easily cut off the line
The multilayer board refers to a printed board having three or more conductive pattern layers interposed therebetween and interposed therebetween so that the conductive patterns are interconnected as required. Multi-layer circuit board is the electronic information technology to high-speed, multi-functional, large capacity, small size, thin, lightweight direction of the product.
Q:PCB board in the multi-layer is what it means
Since the drilling and plating have been completed before all the layers have been rolled together, this technique has violated the traditional production process from the outset. The innermost two layers consist of a conventional double-sided panel, while the outer layers are different, and they are made of separate single-sided panels.
Q:What is the working principle of the circuit board?
On the most basic PCB, the parts are concentrated on one side and the wires are on the other side. Because the wire only appears on one side, the PCB is called a single panel. Multi-layer board, multi-layer wire, must be between the two layers of the appropriate circuit between the job, the bridge between the circuit called the hole (via).
Q:Bypass the schematic to turn directly to the PCB board
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:PCB circuit board? What is it?
Usually the colors of the PCB are green or brown, which is the color of the solder mask. Is an insulated protective layer that protects the copper wire and prevents parts from being welded to the wrong place. In the solder mask layer will be printed on a layer of screen printing surface (silk screen). Usually on this will be printed on the text and symbols (mostly white), to mark the parts on the board position. Screen printing is also called the icon (legend).
Q:Which boards are difficult boards?
Process capacity; generally HDI, rigid-flex; ordinary factory to do 2/2 line yield is not ye to the
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:What does the printed motherboard mean?
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:Circuit board A what it means
Single-panel is usually simple to manufacture, low cost, but the disadvantage is not applied to too complex products.
