Polychlorinated biphenyls are widely used in industry and have caused global environmental pollution problems. Polychlorinated biphenyls produced in production...

Guidance The detection of PCB boards is time to pay attention to details, so as to ensure product quality better. When we detect PCB boards, we should pay attention to the following night common sense.  Night Basic Common Sense for  Detecting  PCB Board Night common sense for the Basic Testing of PCB Board 1.It is strictly prohibited to detect the PCB board with a grounded test equipment to contact the live TV, audio, video and other equipment in the floor without isolation transformer. It is strictly forbidden to directly test the TV, audio, video and other equipment of the transformer without power isolation by the equipment that has been grounded. Although have the power transformer recorder in general, when exposed to a special especially larger output power or do not understand the nature of the power of television or audio equipment, we must first understand the chassis is electrified, otherwise easily with the bottom charged television, sound and oth...
