RCY ELECTRONIC : How to judge the quality of PCB board?

1  Distinguish the quality from the pcb appearance Under normal circumstances,  we can analyze and judge the appearance of PCB circuit board through following three aspects. 1)     Standard rules for size and thickness. The thickness of the board to the standard board is different, and the customer can measure and check the thickness and specifications according to their own products. 2)  Light and color The external circuit board has ink coverage on the surface of pcb board, which can play the role of insulation for the circuit board However, if the pcb board has no bright color and the reflective light is poor, we can say that there is less ink on the pcb board. So, the board itself is not good 3)  The appearance of the welding Due to the large number of components and parts on the pcb board. But, if the welding is not good, which will cause components and parts easy to fall off. What's more, poor welding  seriously affects the  quality of the...
