Q:What is the full name of PCB?
The printed circuit board is not a general terminal products, so in the name of the definition of slight confusion, such as a personal computer with a motherboard, called the motherboard, but not directly called the circuit board, although the host circuit board in existence, but is not the same, so the evaluation of the industry when they are related but can not say the same. For example: because there are integrated circuit components on the circuit board, so the press called him IC board, but in fact he is not equivalent to the printed circuit board. The printed circuit board we usually refers to the circuit board that no bare board components.
Q:What is the raw material of FPC?
The flexible circuit board (flexible PCB): referred to as "soft board", also known as the "flexible circuit board", also known as the "flexible circuit boards, flexible circuit board or flexible circuit board and flexible circuit board, English is" FPC PCB "or" FPCB Flexible and Rigid-Flex ".
Q:What is the LPC inspection standard for PCB?
The inspection standard of flexible board is IPC-6013H; other HDI boards and metal substrates have corresponding standards.
Q:What are the circuit board material?
There are many kinds of classification methods of copper clad laminate. According to the general board reinforced with different materials can be divided into: paper base, glass fiber cloth, composite base (CEM Series), build up multilayer plate base and special material (ceramic, metal core based) five categories. According to the different resin adhesive used in the classification, the common paper based CCI. There are: phenolic resin (XPc, XxxPC, FR 1, FR 2, etc.), epoxy resin (FE a 3), polyester resin and other types. Glass cloth CCL common epoxy resin (FR 4, FR 5), it is the most widely used type of glass fiber cloth at. In addition to other special resin (glass fiber cloth, poly amide fibers, non-woven fabrics and other materials to increase): bismaleimide modified three triazine resin (BT), polyimide resin (PI), two phenylene ether resin (PPO), maleic anhydride imide - styrene resin (MS), poly isocyanate ester resin, polyolefin resin etc..
Q:The difference between soft PCB and rigid PCB
Because the flexible foil plate can be continuously coiled, the continuous production of flexible PCB can be realized. It also helps to reduce costs.
Q:How to enlarge the size of the existing PCB board?
PCB board: printed circuit board {PCB circuit board}, also known as printed circuit board, is the electronic components of the electrical connection provider. Its development has been more than 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 rate.
Q:Several kinds of circuit boards
In addition to other special resin (glass fiber cloth, poly amide fibers, non-woven fabrics and other materials to increase): bismaleimide modified three triazine resin (BT), polyimide resin (PI), two phenylene ether resin (PPO), maleic anhydride imide - styrene resin (MS), poly isocyanate ester resin, polyolefin resin etc..
Q:What materials are needed in PCB plant?
According to the classification of CCL flame retardant performance, can be divided into flame retardant (UL94 a VO, UL94 a V1 class) and non flame retardant (UL94 a HB) two kinds of board. In the past one or two years, with the more attention to the environmental protection problem, a new kind of bromine free CCL variety, which is a new type of flame retardant CCL, can be called "green flame retardant cCL". With the rapid development of electronic technology, cCL has higher performance requirements. Therefore, from the performance of the CCL classification, is divided into the general performance of CCL, low dielectric constant CCL, high heat resistance of the CCL (general board of L above 150 degrees Celsius), low thermal expansion coefficient of CCL (commonly used for packaging substrate) and other types
Q:Circuit board PCB according to the material can be divided into several? Where are they used?
The current mainstream PCB material classification are the following: the use of FR-4 (glass fiber cloth), CEM-1/3 (glass fiber composite substrate and paper), FR-1 (paper-based cover copper), metal base copper clad laminate (mainly aluminum base, a Fe based material type) above the common, generally referred to as rigid PCB.
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.
