Q:On the PCB shop copper problem, if it is a double panel, is not also do not have to layout the ground, both sides of the shop copper, and finally casually playing some holes?
It is best to first walk with a fine line to see if the place to be able to, to ensure that can be reached, and then copper. Otherwise, it is easy to cause some parts of the barrier, and sometimes you can not see
Q:What is the difference between a single and double-sided package?
Because the single-panel has many stringent restrictions on the design line (because there is only one side, the wiring can not cross and must be around the path), so only the early circuit to use such boards; single-panel wiring diagram to the network printing
Q:What does the double-sided panel mean?
Because the earliest, the most difficult is the hole in the copper (how in the copper wall of copper without copper), this is the distinction between the double-sided, single-sided the most important basis.But the double double-sided, but both sides of the copper, but the hole
Q:How do you make a double panel with fiberglass?
The production method mainly comprises the following steps: 1, using the mold and mixing the raw materials according to the ratio and pouring into the mold; 2, putting the filler; 3, heating and cooling
Q:What is the process of making a double panel
remove the drilling generated (5 minutes, degreasing, in addition to oxide, adjust the charge). If the hole is not transparent, use the smallest drill bit piercing. 60 ℃, for 5 minutes, the temperature is not enough, the time is long) Washing (washing is to remove the residual medicine) Drying (remove the residual moisture in the hole) [Note: 100 ℃] activation (2 to 4 minutes,
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:Three open double panel is what it means
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: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 a single panel and a double panel?
Because the single-panel has many stringent restrictions on the design line (because there is only one side, the wiring can not cross and must be around the path), so only the early circuit to use such boards; single-panel wiring diagram to the network printing (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: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.
