(1) not allowed in the printed circuit crossover circuit that might cross the line, you can use the "drill", "around" two kinds of solution. That is, to a lead from other resistors, capacitors, transistors, the gap at the foot of "drill" In the past, or may cross from one end of a lead article, "around" the past, in exceptional cases to the circuit is very complicated, to simplify the design permits the use of jumper wire, cross-circuit problems to solve.

For electronic products, printed circuit board design is from the electrical schematic into a specific product must pass through a design process, the rationality of its design and product production and product quality are closely related, and for many just in the electronic design staff, the less experienced in this area, though have learned a PCB design software, but the design of printed circuit boards often this kind of problem, and many electronic journals, this article presents a rare, I have many years of work in the PCB design, PCB design in this bit of experience to share with you, hoping to play the role of better ideas. A few years ago the author of the PCB design software is TANGO, now use PROTEL2.7 FOR WINDOWS.

To complete the requirements of testing printed circuit boards, has produced a variety of testing equipment. Automatic optical inspection (AOI) systems are commonly used as the inner layer of the test before; in after stratification, X-ray system monitoring the accuracy of the position and small defects; scanning laser system provides a layer in the pad before the detection of reflux methods. These systems, coupled with production lines and automatic visual inspection of components placed on the integrity of components, testing, final assembly and will help to ensure the reliability of welded plates.

Plating process is currently widely used in various areas of national product, only serious action to effectively conserve energy, protect the environment. In the following a brief introduction on some basic knowledge of plating. Plating Category: Acid Bright Copper

FPC is currently the most used batch processing or cutting, small-volume samples of FPC and the FPC is mainly used in CNC drilling and milling processing.
