Electro Static Discharge What is ESD ? Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown Static Energy Definition: Electrostatic discharge (ESD) Electrostatic discharge sensitive device (ESDS) ESD protected area (EPA) EPA ESD ESDS ESD protective material: Conductive: Materials with an electrical resistance between 1kΩ and 1MΩ Dissipative: Materials with an electrical resistance between 1MΩ and 1TΩ Type of ESD classification: Human Body Model (HBM) Machine Model (MM) Charge Device Model (CDM) Human Body Model: The model is a simulation of the discharge which might occur when a human touches an electronic device,. Machine Model: Also known as the 0-Ω model, MM is designed ...
Surface Mounding Technology: What is SMT? Surface-mount technology ( SMT ) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device ( SMD ). 5-S PRINCIPLE: The original “S”s are actually Japanese words which translate loosely into English as: SORT SET SHINE STANTATIZATION SUSTAINCE SORT: Remove all items not needed from the work area , Creates a work environment that : Mass Space Uses less energy Save time SET: Arrange the necessary items in good order and easy access Arrange items in an easy to use manner Anyone can fi...
