Q: How many kinds of materials are printed circuit boards? Which is the best?: 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. 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..

Q: Why do you need UL certification?: However, a large number of manufacturers do not represent the industry has a deep understanding of UL standards. A certification advisory 1, single plate (single + single-sided double-sided single-layer) UL certification, UL certification 2 prefabricated multilayer board 3, multilayer board UL certification UL certification 5, 4 metal plate, flexible circuit board for 6, two new materials, process, circuit board certification training and factory audit, deal with 1 printed circuit in the UL standard and product category 2, interpretation of the printed circuit board UL, UL report of 3 test items: B/D, combustion test, thermal shock, etc. 4 UL mark requirements 5, how to find the UL website archives information 6, factory audit should pay attention to matters 7, how to avoid being VN and VN to deal with

Q: What is the difference between rigid and flexible printed circuit board designs?: A significant advantage of the application of soft PCB is that it can be more convenient in three-dimensional space line and assembly, but also can be curled or folded up. As long as the radius of curvature within the allowable radius of curvature, can be used for thousands to tens of thousands of times without damage.

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: Why don't you get rid of PCB hard PCB?: Manufacturing factors: the rigidity of the plate is higher than the flexible plate

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: Is the circuit board poisonous?: The name of the circuit board are: circuit board, PCB board, aluminum substrate, high frequency board, PCB, ultrathin circuit board, ultrathin circuit board, printed circuit board, printed circuit board, Kunshan circuit board, etc. all of the circuit board

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 are the materials of electronic circuit board? From the elements of the composition of the material, which elements of the composition of the plate?: 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..

Q: Circuit board plant classification: When we turn on the keyboard of a general-purpose computer, we can see a soft film (flexible insulating substrate), printed with a silver white (silver paste) conductive pattern and a healthy figure. Because the universal screen stencil method to get it, so we call this printed circuit board PCB, flexible printed circuit board silver paste PCB. And we go to the computer city to see a variety of computer motherboards, graphics cards, network cards, modems, sound cards and home appliances on the printed circuit board is different.
