Paul Eisle invented the first PCB in 1936. However, it became popular only in the 1950s when the US military started using the technology in bomb detonators. Today, PCB Circuit Boards are an integral part of almost all equipment, like cars, mobile phones, computers and more. How Is A Printed Circuit Board Manufactured?To make a custom PCB, first the electronic diagram of the required circuit is prepared using Computer Aided Design (CAD) software. After that the PCB prototype is developed using Computer Aided Manufacturing Software technology. The common materials used for manufacturing PCBs are: FR4, FR4 High Temperature, Polyimide, GeTek, Rogers, Arlon, Nelco, Alumina, Ceramic, Bakelite, FR1, CEM1, and CEM5. The size and thickness of the board depends upon the requirements of the circuit. The substrate is coated with a layer of copper. Then, using photosensitive coating, the circuit diagram is printed on the board. The undesired copper is etched out from the board to form copper "tracks", called traces. This process is known as Photoengraving. There are two other common methods used for developing connecting traces. PCB milling is a mechanical system where undesired...more

Telling the Truth: An Insider's Look at: How far will be safe when using home applianceComputers, air conditioners, refrigerators, hair dryer, electric razor ... ... These are people used every day "life helper," However, these appliances will produce electromagnetic radiation, when people use the appliance can not help but worry that they produce electromagnetic radiation will affect their health. Zhao Yufeng,the chairman of China Indoor Environment Monitoring Committee Experts Committee,said that the amount of electromagnetic radiation vary with appliance styles, not that all of the electromagnetic radiation will cause harm to human body as long as maintaining a safe distance with the appliance, it will effect the health of our body. Then, how bad effects for the electromagnetic radiation? How to keep a safe distance with it? Representative of relatively safe appliance appliances include washing machines, refrigerators, electric shavers, air conditioning, kitchen mixers, rice cooker, electric iron.Zhao Yufeng describes, in general, these appliances of rated power is around 50 Hz, and their electromagnetic radiation intensity is not high, even from people close to that, it...more
