Q:What kind of circuit board

Different pressure requirements, and heat requirements, choose different materials

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:PCB carbon oil plate is what kind of technology?

PCB carbon oil board to print "E" carbon oil area, it is best to draw in the 99SE inside (also can be drawn in other software), you can not draw, but you want to solder the window in 99SE to do a good job

Q:What is the difference between a drill and a two drill in the PCB type?

PCB drilling is a process of PCB plate making, but also a very important step. The main board is to punch lines, to make a hole, make a hole in the structure to do what the multilayer board positioning; not a finished drilling, some buried hole in the circuit board, some of them get through the above board, so there will be a two diamond drill.

Q:Why do you need UL certification?

So far, there have been more than 2 thousand PCB board manufacturers successfully obtained UL certification, which is the majority of rigid circuit board.

Q:Circuit board plant classification

Hard soft board flex joint strength according to the sun

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

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.

Q:What is the full name of PCB?

The full name of PCB is Printed Circuit Board, namely printed circuit board.
