ELECTRONIC PACKAGING DESIGN

Electronic packaging is the design and production of enclosures for electronic devices ranging from individual semiconductor microchips up to complete systems such as a mainframe computer. Electronic packaging is arguably the most complex among all levels of packaging as it requires extensive engineering and skill set in order to come up with an optimal overall electronics packaging design compared to other industry packaging designs. Electronic packaging is a major discipline within the field of mechanical engineering. There are different levels of electronic packaging, and these levels are necessary to help engineers easily identifies electronic packaging materials needed for an electronic packaging design.

The electronic packaging design is a combination of minor electronic packages working altogether to achieve desires purpose. Packaging of an electronic system must consider protection from mechanical damage, cooling, radio frequency noise emission and electrostatic discharge. Product safety standards may dictate particular features of a consumer product, for example, external case temperature or grounding of exposed metal parts. Prototypes and industrial equipment made in small quantities may use standardized commercially available enclosures such as card cages or prefabricated boxes. Mass-market consumer devices may have highly specialized packaging to increase consumer appeal. Wikipedia

UNDERSTAND BASIC ELECTRICAL CONCEPTS

• design, fabricate, sample electrical/electronic circuits for testing and evaluation.
• design a functional PWB/Printed circuit board (Printed Wiring Board) that is able to support both electrical and mechanical requirements for all components needed to assemble a PWB for a Low Voltage Power Supply.
• identify a digital logic gate through both schematic symbolism and Truth Tables.
• knowledge of power generation, transmission, and basic electrical theory.
• measure AC/DC Voltages and Currents, Resistance using both a Bench and Portable DMM.
• measure various electrical quantities, using a DMM. The quantities to be measured will be: resistance, AC/DC Current, and AC/DC Voltage.
• understand schematic diagram and able to assemble, test and measure the circuit for its operational parameters.
• use an Electronic Simulation Software Package (similar to Multi-Sim or Spice) to supplement both the understanding and analysis of Direct and Alternating Current Circuits (see impedance, and resonance).
• use an Oscilloscope (Analog/Digital) to determine waveform type, measure both time and voltages.
• understand OSHA Safety (basics of electricity) covered details including voltage, current, and resistance. How each of these elements form mathematical relationships with one another usings Ohm's Law and the Power Equation/Steinmetz's equation.

ELECTRONIC PACKAGING & DESIGN

Electronic packaging is the design and production of enclosures for electronic devices ranging from individual semiconductor devices up to complete systems such as a mainframe computer. Packaging of an electronic system must consider protection from mechanical damage, cooling, radio frequency noise emission and electrostatic discharge. Electronic packaging is a major discipline within the field of mechanical engineering.

Design: Electronic packaging design is the skilful balancing and engineering of design trade-offs at all levels of packaging while working to produce an optimal overall system design. The different design options available have the potential of producing conflicts between some of the packaging functions if they are not carefully chosen. Design choices must be weighed and made for every level of interconnection. These choices must be consistent with existing design practices and available manufacturing technology. These trade-offs need to be carefully formulated at the initial system conceptual design stage. As the hardware is built and tested, some of the initial trade-off decisions are generally revisited and rethought. Decisions made at this initial stage need to be sound and well thought out. The broad directions must be correct for the design effort to succeed. The system’s success or failure can be sealed at this stage.

Electronic Circuit Design: To design any electrical circuit, either analog or digital, electrical engineers need to be able to predict the voltages and currents at all places within the circuit. Linear circuits, that is, circuits wherein the outputs are linearly dependent on the inputs, can be analyzed by skilled technician using complex analysis. Complex digital circuits are typically designed with the aid of computer software and specialized software such as SPICE and EMTP had been created to analyze complicated or too nonlinear circuits. Simple circuits may be designed by connecting a number of elements or functional blocks such as integrated circuits. Developing subject, please check back later.

ELECTRONIC & ELECTRICAL TERMS

Light/Surge Voltage Protector: A surge protector or surge suppressor is an appliance or device designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold.
