Q:What is the cost standard of circuit board?
Maintenance side should be based on the detection of the failure of the case to be reasonable charges.
Q:How much is the warpage of the circuit board, and how to detect the warpage of the FPC?
Method for detecting warpage is put on the printed circuit board by the test platform, the test needle to warp the largest local, in order to test the diameter of the needle, divided by the PCB curved edge length, we can calculate the soft board warpage.
Q:Why does the FPC circuit board have positive and negative layers?
More than FPC (flexible plate), PCB also has a positive and negative layer.
Q:The prospect of flexible circuit board
Its representative flexible substrate is PET. Polymer thick film conductor including screen printing metal filler or carbon filler. Polymer thick film method itself is very clean, use lead-free SMT adhesive, without etching.
Q:Circuit board PCB according to the material can be divided into several? Where are they used?
Before the three commonly applied to high performance electronic insulation requirements of products, such as FPC PCB drilling plate reinforcement plate, glass fiber, carbon film potentiometer meson, printing glass fiber board, precision planetary gear (wafer), precision test sheet, electrical equipment (Electrical) insulation insulation plate, strip baffle, transformer insulation board motor, insulation parts, gear grinding, electronic switch insulation board.
Q:How to enlarge the size of the existing PCB board?
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 full name of PCB?
In accordance with the number of circuit boards can be divided into single panel, double-sided board, four plates, the six board and other multilayer circuit board.
Q:Why don't you get rid of PCB hard PCB?
Design factors: the need for the use of plug-in components of the PCB, can only use the rigid plate, what you say and there are a lot of stress; the PCB, can only use the rigid plate
Q:What are the circuit board materials?
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.. 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:What are the materials of electronic circuit board?
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.
