Q:PROTEL99 PCB double panel how to draw: To set the design rules, click Rules under the Design menu, open the Rules tab, click the NetsTOIgnore network under Placement, and select the network that you want to ignore.

Q:How to draw double-panel single-chip? The How is the connection between the board and the board?: The holes used in the double panels are metallized holes, that is, conductive holes, which can connect two layers of wires. In fact, in the automatic routing do not have to consider these, and as long as the double-sided painting, in the processing of these are not to worry about.

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: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:Can the double panel be used as a wardrobe?: According to their density, divided into high density board, MDF, low density board.

Q:What kind of PCB board is called HDI board?: 1) .pcb. The most common suffix, a lot of PCB design files are the suffix, one of the most common is Protel99, PADS, in addition to including ZUKEN company Cadstar, CR5000, Altimum P-CAD,

Q:What is the difference between a single and double-sided package?: (Screen Printing), which is printed on the copper surface of the resistance agent, after etching and then to the resistance of the printed mark on the resistance, and finally to punch the way to complete the parts guide hole and shape. In addition, a small number of diverse production of products, the use of photoresist to form a pattern of photography.

Q:Can the double panels be painted?: Their brush should not be good, there will be a brush printed, two brush was uneven, anti-background, the degree of attachment is not good. The The The So it is necessary to look at what material is the double panel, or not paste the skin, if not posted leather can try with the brush.

Q:What does the double-sided panel mean?: Which does not have copper, so that the hole without copper, but the double side of the pain of the circuit board, called false double panel, looks double panel, the actual and double-sided is different!

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.
