Q: Why do you need UL certification?: Products into the United States, customs and also to carry out UL security certification inspection.

Q: What is the meaning of flexible circuit boards and rigid circuit boards?: The rigid printed board is made of phenolic paper laminated board, epoxy paper laminated board, polyester glass felt laminated plate and epoxy glass cloth laminated board.

Q: What is the tolerance range of the size of the copper foil of the PCB board?: The specification of the substrate thickness and deviation is divided into A/K (commonly known as 1), B/L (commonly known as grade 2), C/M (commonly known as the 3 level), D. The thickness of A, B, C level is the thickness of the clad metal foil, the thickness of K, L and M is the thickness of the metal foil after the laminate, and the D level is used to measure the minimum thickness of the substrate.

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: 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?: According to the United States IPC-6012 (1996 edition) rigid printed board identification and performance specification, flexible circuit board for surface mount printed board to allow maximum warpage and distortion of 0.75%, the other various boards allow for the use of 1.5%.

Q: What's the difference between PCB and FPC?: In a broad sense, PCB includes FPC.

Q: What is the raw material of FPC?: The flexible circuit board (flexible PCB): referred to as "soft board", also known as the "flexible circuit board", also known as the "flexible circuit boards, flexible circuit board or flexible circuit board and flexible circuit board, English is" FPC PCB "or" FPCB Flexible and Rigid-Flex ".

Q: What's the difference between PCB and FBC?: A culture method for batch or continuous addition of one or more ingredients in a batch fermentation process

Q: The prospect of flexible circuit board: In the next few years, smaller, more complex and more expensive assembly of flexible circuits will require more novel methods of assembly, and the need to increase the hybrid flexible circuit. The challenge for the flexible circuit industry is to keep pace with the computer, telecommunications, consumer demand and active market. In addition, the flexible circuit will play an important role in the lead-free operation.
