Detection Instrument

In this paper, several aspects were studied, including the effect of an electromagnetic interference (EMI) noise interference strategy with High Definition Multimedia Interface (HDMI) 1.4, the analysis of a test on a printed circuit board (PCB) layout, and a comparison of the near field intensity radiation distribution between an EMI with a modified HDMI layout and an original layout. In this study, the near field detection instrument of APREL EM-ISight was employed to analyze the distribution of the strength of an electromagnetic noise field. After the practical validation, we found that the PCB layout complies with the standards after the modifications. Meanwhile, the PCB layout satisfies the requirements of most laptop HDMI-related products for EMI.

This paper presents an approach to find the optimal design layout of chips on a circuit board in a manner that minimizes the area covered on the board and the connections between the various chips. In addition, there are no major heat sources next to each other and certain physical constraints are satisfied while finding a layout design. In this approach, the whole circuit board area is divided into a finite number of cells for mapping it into a Genetic Algorithm (GA) chromosome. The mutation and crossover operators have been modified and are applied in conjunction with connectivity analysis for the chips to reduce the creation of a lot of faulty generations. Examples of GA based chip layout are presented to show how each of the objectives are attained separately followed by examples to arrive at layouts using multiple objectives.

Pcb Layout

A technique of PCB layout optical inspection based on image comparison and mathematical morphology methods is proposed. The unique feature of the technique is that the inspection is performed at different stages of image processing. The presence of all layout elements is checked up, then positions of found elements and their conformity to project rules are verified, the breakouts and shorts are found. The inspection of mousebits, spur and pinholes on conductors is also carried out.

Pcb Layout

This paper presents an empirical approach backedby LTspice simulation to optimize switching performance in halfbridgeconfiguration. For a given layout effective value of RCnetwork in gate drive loop, ways to avoid dV/dt induced false turnonof MOSFET and remedial circuit for minimizing parasiticoscillation at switching nodes have been presented. Entire studyhas been validated using LTspice simulation as it’s not possible tobuild a hardware board which can cover all the design aspectsauthors wanted to cover. Idea is to present a systematic approachwhich a practicing engineer can adopt for optimizing switching ofMOSFET in a given PCB layout.
