Surface Mounding Technology

                       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 to simulate a machine discharging through a device to ground.

                                                             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 find them Anyone can put them away The key is “anyone” Eliminates waste due to searching SHINE: Clean your workplace thoroughl
