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: Draw soft PCB and rigid PCB distinction should pay attention to what the process of some specific requirements?: 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.

Q: What is circuit board: The circuit board is mainly composed of the pad, the hole, the mounting hole, the wire, the components, the connector, the filling, the electrical boundary and so on

Q: What are the circuit board display devices?: The circuit board is mainly composed of the pad, the hole, the mounting hole, the wire, the components, the connector, the filling, the electrical boundary and so on.

Q: How much is the warpage of the circuit board, and how to detect the warpage of the FPC?: At present, the degree of warpage of the electronic assembly plant license, whether double-sided or multilayer, 1.6mm thickness, usually 0.70 ~ 0.75%, many SMT, BGA board, the requirement is 0.5%.

Q: What is the cost standard of circuit board?: The customer confirmed after repair, transport costs borne by us.

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?: 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's the difference between PCB and FBC?: The PCB circuit board, is specialized in the production of circuit boards.

Q: PCB carbon oil plate is what kind of technology?: PCB carbon oil board to print "E" carbon oil area, it is best to draw in the 99SE inside (also can be drawn in other software), you can not draw, but you want to solder the window in 99SE to do a good job

Q: What is a circuit board milling machine? And numerical control which is easier?: You should refer to a carving machine, the system is very simple, the main processing circuit board substrate, low rigidity, small scope of application
