Q:What is circuit board: Both sides of the circuit board are wired. However, to use both sides of the wire, you must have a proper circuit connection between the two sides. The "bridge" between such circuits is called a guide hole (via). A guide hole is a small hole filled or coated with metal on PCB, which can be connected to a wire on both sides. Because the area of the double sided board is twice larger than that of the single panel, and because the wiring can be interlaced (which can be turned around to the other side), it is more suitable to be used in a more complicated circuit than a single panel.

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:Cover film: for the protection of the flexible circuit board or circuit board that, above a layer of glue, if not in normal temperature down too long, please at room temperature (or 30 degrees) can affect the product quality will not keep long?: Electronic circuit board product storage, general requirements: single box storage; to have anti-static and moisture-proof measures; the single box can not be too high according to packing storage.

Q:What are the materials of electronic circuit board? From the elements of the composition of the material, which elements of the composition of the plate?: 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). There are many kinds of classification methods of copper clad laminate.

Q:Do PCB circuit board which plate: 3) flame retardant copper clad epoxy /PPO glass cloth laminated sheet and adhesive sheet material. IPC4101 detailed specification number 25; Tg 150 DEG C ~200 c;

Q:What are the circuit board materials?: 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:The circuit board with strong is how to do?: The method of reinforcing and connecting lines is hot pressing and cold pressing. Hot pressing is the use of high temperature conditions, so that the reinforcement of the epoxy resin melting, and thus combined with the line; cold pressure is the use of some of the adhesive glue at room temperature, directly bonded together.

Q:PCB carbon oil plate is what kind of technology?: Then specify which buttons to print carbon oil, such as the key pad to cover how much mil is enough, manufacturers see this file is also very clear

Q:What kind of circuit board: Metal plate is mainly aluminum substrate, copper substrate and so on
