Double-sided circuit boards are mainly designed to solve the complex design of the circuit and the area of the board, both sides of the board are installed components, double or multi-layer alignment.
Both sides of the two-sided circuit board have wiring. Double PCB But to use the two sides of the wire, must be between the two sides have the appropriate circuit connection Caixing.
Double-sided circuit board is a very important board in a PCB board, his use is great, to see a board PCB board is not double-sided circuit board is also very simple, I believe that friends on the single-panel understanding is complete Can be grasped, Double PCB double-sided circuit board is an extension of a single panel, meaning that the single-sided line is not enough to go to the reverse side, double-sided circuit board is an important feature is a vias. simple Point that is double-sided line, both sides have lines! A generous is: double-sided board is a double-sided circuit board! Some friends will ask such as a board double-sided line, but only one Surface with electronic parts, such a board in the end is a double-sided circuit board or a single panel? The answer is obvious, Double PCB this board is a double-sided circuit board, but in the double-sided circuit board plate mounted on the parts Just now. Multi-layer circuit board to distinguish the number of wiring board according to the number of wiring to determine the difficulty of processing and processing prices, the ordinary circuit board points single-sided and double-sided alignment, Double PCB commonly known as single-sided and double-sided circuit boards , But the high-end electronic products, due to product space design constraints, in addition to surface wiring, the internal stack of multi-layer lines, the production process, Double PCB making a good line after each layer, and then through the optical Equipment positioning, pressure, so that multi-layer lines stacked in a circuit board.
Double-sided circuit board processing of the fixed method, belonging to the field of fixed processing technology.
The double-sided circuit board machining process is fixed by means of a plurality of pins 2 cut off with the production plate 3 to secure the production plate 3 to ensure that the drilling process is drilled in the plate to ensure machining accuracy and Graphics offset caused by the process after the scrapped, Double PCB while increasing staff efficiency and reduce the cost of positioning machine platform. The above-described embodiments are merely illustrative of the technical concept and features of the present invention It will be understood by those skilled in the art that the present invention may be understood and practiced without limiting the scope of the invention, and that equivalents or modifications in accordance with the spirit of the invention , Double PCB Both of which are to be covered within the scope of the present invention.
A method of fixing a double-sided circuit board process comprising the steps of 1) fixing a pad (I) to a rig table; 2) drilling a plurality of positioning on said plate (I) Holes; said plurality (2); 4) the production plate (3) is fastened to the pin (2), and the pin (3) is fixed to the pin between.
2. A method of fixing a double-sided circuit board process according to claim I, characterized in that said backing plate (I) is horizontally fixed to the rig table.
3. A method of fixing a double-sided circuit board process according to claim I, characterized in that said backing plate (I) is rectangular; said positioning hole has four, Double PCB four positioning holes are respectively provided in a rectangular pad The center line of the four sides of the plate (I).
4. A method of fixing a double-sided circuit board process according to claim I, characterized in that the diameter of each of the positioning holes coincides with the diameter of the pin (2).
5. A method of fixing a double-sided circuit board process according to claim I, Double PCB characterized in that the production plate (3) is fastened between the pins (2) and to the plate (I).
The method of fixing the double-sided circuit board processing process comprises the following steps 1), fixing the pad on the rig table; 2) drilling a plurality of positioning holes on the pad; the plurality of positioning holes 3), in each of the positioning holes are inserted into the pin; 4), Double PCB the production board is fastened between the pins; this double-sided circuit board processing process of the fixed method, through the more One And the production board cut the pin to the production board fastening, to ensure that the drilling process in the plate drilled, to ensure the processing accuracy, to avoid the graphics shift caused by the process of scrapping, while increasing staff Efficiency and reduce the cost of locating the machine.
