Q: Structure of flexible circuit board: General substrate + transparent adhesive + copper foil is the first process of making holes. First in the base material and copper foil drilling, cleaning after plating on a certain thickness of copper, the hole is done. The production process is almost the same as that of a single plate. The structure of the double sided board: both sides of the two sides of the board, mainly used to connect with other circuit boards. Although it is similar to the single plate structure, the manufacturing process is very different. Its raw materials are copper foil, protective film + transparent adhesive. First, according to the requirements of the position of the pad on the protective film on the hole, and then put on the copper foil, the corrosion of the pad and the lead and then paste another hole drilled protective film can be.

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: Draw soft PCB and rigid PCB distinction should pay attention to what the process of some specific requirements?: Because the flexible foil plate can be continuously coiled, the continuous production of flexible PCB can be realized. It also helps to reduce costs.

Q: What is the difference between rigid and flexible printed circuit board designs?: When the soft PCB is connected, the wiring can be reduced on the three planes of X, Y and Z, so that the switching interconnection is reduced, and the reliability of the whole system is increased.

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?: Electronic circuit board product storage, general requirements: single box storage; to have anti-static and moisture-proof measures; the single box can not be too high according to packing storage.

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: Do LED soft light with which kind of circuit board: Mainly used as electronic components of the conduction volume relative to the PCB is small, the corresponding space is small, but the price is expensive. Above is my understanding of the board, I hope to help you.

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: Why does the FPC circuit board have positive and negative layers?: For the bottom, the general is a large copper skin, then use the negative layer is very small storage space, convenient to send.

Q: PCB carbon oil plate is what kind of technology?: PCB carbon oil plate is a rigid circuit board technology, carbon oil plate is a common single and double sided surface treatment.
