Because of the printed circuit board is more "chaotic", so the following methods and techniques can improve the speed of the picture.
(1) according to the characteristics of some components, these components can be easily found. For example, integrated circuits, power amplifiers, switches, transformers, etc..
(2) for integrated circuits, a specific integrated circuit can be found based on the model of the integrated circuit. Although there is no regularity in the distribution and arrangement of components, the components in the same unit circuit are relatively concentrated.
(3) some cell circuits are characterized by their ability to find them easily. If the rectifier circuit in the diode is more, the power amplifier has a heat sink, the largest capacity of the filter capacitor, the largest volume, etc..
(4) when looking for a ground wire, a large area of copper wire on the circuit board is a ground wire. In addition, some components of the metal shell grounding. Any of the above can be used as a ground wire. Among the boards of some machines, which is connected to the ground, but when the connector between each block is not on the ground, between each block of the circuit board is not feasible, it is important to note in maintenance.
