Abstract


This paper describes the process of the realization of a ruggedized notebook computer architecture based on the ETX . Demand for ruggedized notebook computer highlights the design based on the principle of the ETX architecture notebook and motherboard PCB design and debugging test method . The first chapter describes the current situation and development features ruggedized notebook computer field , and the ruggedized notebook computer system implementations . The second chapter describes the laptop motherboard schematic design, extended under the principle , and the bus interface bus connection . Laptop motherboard using ETX architecture , according to the actual needs leads to some non-standard interfaces to other functional modules integrated into the substrate , greatly reducing the space occupied area . This paper describes the specific design of each part of the circuit of laptop motherboard , including circuit schematics , interface definition and design rules . ETX as the core , the design of the power supply, I / 0 and PCI / ISA interface circuit in the surrounding four ETX socket (X1-X4), backplane design . The third chapter describes the hardware of the laptop motherboard PCB design , including layout, alignment rules set , anti-jamming measures . According to the characteristics of the circuit , using a 6 - layer PCB, power supply is designed to separate the inner layer , the power and ground planes were divided , according to the current size of printed circuit boards , try bold power line width , reducing the loop resistance . Chapter IV of the the machine debugging testing process introduced . In the motherboard debug test , the first power supply part of the load and reliability testing , and performance testing machine interface . Finally made ??a summary of content and the results of this study and future development prospects . Subsection ruggedized notebook computers with fast processing speed , low power consumption , easy to expand , wide operating temperature range , the effect of three anti- electromagnetic compatibility , etc. , is a portable laptop computer for use in harsh outdoor environments .
