Q: What are the circuit board materials?: 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.

Q: How many kinds of materials are printed circuit boards? Which is the best?: 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 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: 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: 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?: The temperature requirements for the storage of the film covering for flexible circuit boards or circuit boards are below 50 degrees.

Q: What is the LPC inspection standard for PCB?: The IPC standard for printed circuit boards is IPC-600, which is a general specification;

Q: What is the raw material of FPC?: 2, rigid flexible printed board rigid flexible printed board: English Rigid-Flex Printed Circuit, (FPC), also known as soft and hard board. Rigid flexible printed circuit board is laminated by a rigid and flexible substrate selectively together, compact structure, with metal holes forming a conductive connection, each with rigid flexible one or more rigid zone and one or a plurality of flexible printed circuit board area. The national standard GB/T2036-94 2.11 "printed circuit terminology" just flexible printed circuit board (FPC) explanation is: the use of flexible substrates and in different regions and with rigid substrate made of printed board, rigid flex in the region, a conductive pattern flexible substrate and a rigid substrate are often interconnected.

Q: What can be used in the print output system for printed board production?: PCB (Printed Circuit Board), the Chinese name for printed circuit boards, referred to as printed circuit boards, is one of the important components of the electronics industry.

Q: What's the difference between PCB and FBC?: It is a transitional culture between batch fermentation and continuous fermentation

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
