Q:What is the difference between rigid and flexible printed circuit board designs?
Connected with the soft PCB, eliminating the error of wire cable connection. As long as the processing drawings after proofreading, all produced after the winding circuit are the same. When the connection line is not wrong.
Q:Why do you need UL certification?
However, a large number of manufacturers do not represent the industry has a deep understanding of UL standards. A certification advisory 1, single plate (single + single-sided double-sided single-layer) UL certification, UL certification 2 prefabricated multilayer board 3, multilayer board UL certification UL certification 5, 4 metal plate, flexible circuit board for 6, two new materials, process, circuit board certification training and factory audit, deal with 1 printed circuit in the UL standard and product category 2, interpretation of the printed circuit board UL, UL report of 3 test items: B/D, combustion test, thermal shock, etc. 4 UL mark requirements 5, how to find the UL website archives information 6, factory audit should pay attention to matters 7, how to avoid being VN and VN to deal with
Q:What kind of circuit board
Different pressure requirements, and heat requirements, choose different materials
Q:The circuit board with strong is how to do?
Rigid circuit board is not reinforced, only flexible circuit board used to reinforce. Because of the serious deformation of the fixed position of the flexible circuit board, a kind of reinforcement is usually added to fix it.
Q:What's the difference between PCB and FPC?
PCB (PrintedCircuitBoard), Chinese name for the printed circuit board, and the printed circuit board, printed circuit board, is an important electronic components, electronic components supporting body, is the electrical connection of electronic components provider. Because it is made of electronic printing, it is called "printed" circuit board.
Q:What is the cost standard of circuit board?
Maintenance of the products should be given three months warranty. According to the requirements of customers free design circuit, oil and gas, circuit diagram. According to the size of the project, the selection of materials, equipment selection, should be within a week to customers.
Q:Structure of flexible circuit board
In accordance with the number of layers of copper foil, divided into single board, double layer board, multilayer board, double-sided board, etc.. The structure of the single layer board: the structure of the flexible plate is the most simple structure of the flexible plate. Usually substrate + transparent glue + copper foil is a set of raw materials to buy, protective film + transparent plastic is another kind of raw materials to buy. First of all, copper foil etching process to get the required circuit, the protective film to be drilled to expose the corresponding pad.
Q:FPC circuit board and PCB circuit board which is good
It depends on what you mean by the use of a soft ribbon
Q:Why does the FPC circuit board have positive and negative layers?
Positive layer is the data above the line and the actual line of the same; negative layer is the data line and the actual opposite.
Q:The difference between soft PCB and rigid PCB
The soft PCB is designed for special application, manufacturing, so the circuit design, start wiring and photographic plate by the cost of higher. Unless there is a special need to use soft PCB, usually a small amount of application, it is best not to use.
