Introduction Over the past five years, the development of true analog CMOS processes has led to the use of high-speed analog devices in the digital arena. System speeds of 150 MHz and higher have become common for digital logic. Systems that were considered high end and high speed a few years ago are now cheaply and easily implemented. However, this integration of fast system speeds brings with...

A biochip can obtain various types of genetic information over a short period of time and enable genetic analysis. A biochip needs temperature sensors to measure temperature. A resistance temperature detector temperature sensor chip, made of copper using a printed circuit board, was introduced in this study. A printed circuit board is readily usable for copper pattern design for the substrate o...

The uncertainty associated with managing dynamic capacity problem is the main source of its complexity. This article presents a system dynamics approach to model and analyse operational complexity of dynamic capacity in multi-stage production. The unique feature of this approach is that it captures the stochastic nature of three main sources of complexity associated with dynamic capacity. These...

This paper presents a bandwidth enhancing technique using a modified ground plane with diagonal edges, L-shaped slot and parasitic patches with main patch for the design of compact antennas. The proposed low-cost, compact-size rectangular patch antenna on 4. 7?cm × 3. 6?cm printed circuit board (FR-4) is designed and validated through simulations and experiments. Results show that the ground pl...

Today, time is one of the key factors in making a company the best in its industry. Translating information correctly and efficiently would reduce the time required to communicate between departments not only within a company but also among different companies. STEP, comprising many application protocols, is a standard for the exchange of product model data that has a great capability for descr...

Mentor’s DxDesigner and Expedition schematic capture and printed circuit board tools were chosen to implement a custom high speed signal processing board containing many high pin count Field Programmable Gate Arrays and many high speed serial connections with data rates over 2 Gigasamples/sec. The methodology used to place the parts and route the board involved the interaction of both the DxDes...

We consider the machine setup problem of printed circuit board (PCB) assembly as a combination of a job grouping problem and a minimum setup problem. We formulate the problem as a MIP-model, where the objective is to minimize the weighted sum of the number of setup occasions and the total number of component feeder changes. We also present and evaluate hybrid algorithms based on both grouping a...

The paper examines the effect of using dissipative edge terminations between power and ground planes on the radiation from a printed circuit board. Basically, this consists of resistive loading of the edges of the power/ground plane structure. These edges constitute the main radiating sources for the dominant resonant mode. This has been found to be effective in reducing the impedance at resona...

This paper identifies five key design characteristics of production scheduling software systems in printed circuit board (PCB) manufacturing. The authors consider that, in addition to an effective scheduling engine, a scheduling system should be able to process a preventative maintenance calendar, to give the user the flexibility to handle data using a variety of electronic sources, to run simu...

We consider a multiobjective optimization model that determines components and processes for given conceptual designs of printed circuit board assemblies. Speci cally, our model outputs a set of solutions that are Pareto optimal with respect to a cost and a quality metric. The discussion here broadly outlines an integer programming based solution strategy, and represents in-progress work being ...
