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:What kind of circuit board
Metal plate is mainly aluminum substrate, copper substrate and so on
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:What are some of the PCB substrate materials? How to classify?
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.
Q:What is a circuit board milling machine? And numerical control which is easier?
High end is carving milling machine, and now there is a specialized drilling and tapping machine, the system can be regarded as a real cnc.
Q:Can a polyimide copper clad laminate be used as a rigid plate?
Can, and now the manufacturers are doing in the use of ZBC, such as DuPont, there is such a polyimide copper clad laminate
Q:What is green in the circuit board?
General printed board substrate materials can be divided into two categories: rigid substrate materials and flexible substrate materials. General rigid substrate material is an important variety of copper clad laminate. It is used for reinforcing material (Reinforeing Material), impregnated with resin adhesive by drying, cutting, laminating blank, and then covered with copper foil, as die steel, in the hot press with high temperature and high pressure forming process and made. Generally used in the semi - thick plate, is the copper clad plate in the production process of semi-finished products (mostly glass cloth impregnated with resin, after drying).
Q:What is the meaning of flexible circuit boards and rigid circuit boards?
The utility model has the advantages of good heat dissipation, bending, folding and rolling, and can move freely and freely in three-dimensional space. FPC can be used to reduce the volume, to achieve lightweight, miniaturization, thin, so as to realize the integration of the device and wire connection.
Q:Why do you need UL certification?
So far, there have been more than 2 thousand PCB board manufacturers successfully obtained UL certification, which is the majority of rigid circuit board.
Q:What is the LPC inspection standard for PCB?
The IPC standard for printed circuit boards is IPC-600, which is a general specification;
