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: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 LPC inspection standard for PCB?
The inspection standard of flexible board is IPC-6013H; other HDI boards and metal substrates have corresponding standards.
Q:What is the difference between a drill and a two drill in the PCB type?
The two drill must be behind a drill, that is to say the process is separate.
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:Engraving machine how to choose the circuit board?
Third, the maximum operating speed refers to the speed of the X, Y axis movement. In fact, the circuit board engraving process, the circuit board engraving machine speed is very low, then why should we emphasize this indicator? A high speed represents the driving ability of the motor, which allows it to move fast, it can make a quick stop, on the other hand also represents the assembly track, screw parallel relationship, small damping, will not affect the accuracy.
Q:What are the circuit board materials?
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.. 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 kind of circuit board
Different pressure requirements, and heat requirements, choose different materials
Q:What is the cost standard of circuit board?
The free testing of industrial products.
Q:Circuit board PCB according to the material can be divided into several? Where are they used?
The metal base copper clad laminate is the basic material of the electronics industry, which is mainly used in the manufacture of printed circuit board (PCB), which is widely used in TV, radio, computer, computer, mobile communication and other electronic products.
