Q: What kind of circuit board: Different pressure requirements, and heat requirements, choose different materials

Q: How many kinds of materials are printed circuit boards? Which is the best?: With the development of electronic technology and the continuous progress, the new requirements for printed board substrate materials have been put forward.

Q: What is the meaning of flexible circuit boards and rigid circuit boards?: FPC is widely used in electronics, communications, aerospace and home appliances and other industries.

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 the difference between rigid and flexible printed circuit board designs?: In the same volume, soft PCB and wire cable ratio, under the same load, the weight can be reduced by about 70%, compared with the rigid PCB, weight reduction of about 90%.

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 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 are some of the PCB substrate materials? How to classify?: 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: The prospect of flexible circuit board: Flexible circuit industry is in a small but rapid development. Polymer thick film method is an efficient and low cost production process. In this process, on the cheap flexible substrate, the selective screen printed conductive polymer ink.

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.
