Q: Pcb double panel if there is a simulated ground and digital to the two to be split?: so if you can see the PCB plane a number of areas of copper, and the area by the inductor or resistor connection, it is likely to be different.

Q: PROTEL99 PCB double panel how to draw: GND can then be manually pre-fabricated with GND, pre-distributed to GND and then automatically routed, click on the automatic routing options Lock All Rre-routes (lock pre-wiring) before the small box appears small hook and then click Roue All Can be.

Q: Three open double panel is what it means: General circuit board double-sided, refers to the double-sided copper, and there are metal holes, that is, double-sided copper, and there are copper inside the hole, for the circuit board double-sided, the hole is particularly important copper,

Q: What is a single panel and a double panel? What is the difference between them?: There are many types of PCB boards, but the common is single and double panels. Single-sided board is only one side of the board with copper circuit, and double-sided on both sides have, but the two sides of the circuit can be linked through the hole together, so that the board into a complete circuit.

Q: What is the difference between a single panel and a double panel?: Double board is ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, printed circuit boards, Kunshan circuit boards, special circuit boards, special circuit boards, circuit mills, circuit boards, soft circuit boards, Flexible board, flexible circuit boards, flexible circuit boards, aluminum-based circuit boards, PCB board, circuit boards, circuit boards, PCB board, aluminum plate, high-frequency board, PCB

Q: Protel do PCB circuit board, how to make the back of the double panel also has components: Double-sided are over reflow, the need for high and low temperature, high temperature surface to avoid electrolytic capacitors, smt high temperature surface solder paste, and then smt low temperature surface solder paste, low temperature surface can send those relatively heavy electrolytic capacitors and inductors such as the original Under the machine all the manual welding, processing costs are relatively high.

Q: What is the difference between them and ordinary double panels?: Common printed circuit boards are made of low-end materials, such as: paper substrate, composite substrate, epoxy board (also known as 3240 epoxy board, phenolic board), FR-4 glass fiber board (puzzle plate)

Q: Is currently choosing cabinets, see the double panel door cabinet price is very cheap, in the uv door cabinet to nearly 300, I chose a, using the Jilin forest workers of the plate, double panel door is not Jilin forest workers, But the import of all the UV forest workers in Jilin. The former is 899 a meter, the latter is 1180 a meter, do not know how to choose, I look at the appearance of the cabinet is not too much, but hope to be durable: Double facade cabinet overall gives the feeling is simple and generous, with the same color of the edge of the border, the visual integration of the entire cabinet, with all kinds of kitchen to match, convenient and practical.

Q: Central East e0 double-sided material and how environmental protection: Is the flexible circuit board, and the board has both sides of the line graphics

Q: How to judge the use of double-sided ok ok ah: Plate surface should be smooth, no burr groove marks and planer marks, no glue phenomenon, the board without local yellow, black and other pollution.
