Innovator Bob Tarzwell Retires From PCB Industry to Focus on New Career in Art
I have known Bob Tarzwell for more than 18 years, since he first called me looking for some help with his company. His first words to me were, “Hi, my name is Bob Tarzwell and I own a shop in Carleton Place, Ontario. I need your help."
Karl's Tech Talk: Green Legislation and the Impact on Electronic Materials and Processes
In general, “green” and “environmentally friendly” refer to manufacturing that involves the replacement of toxic substances with less toxic materials, the elimination of materials or processing steps, less consumption of chemicals (i.e., more efficient or higher yield processing), reduction of water use, reduction of energy use, less space requirement (i.e., smaller equipment footprint), recycling, and on-site recovery of materials.
IPC APEX EXPO: IPC's Fern Abrams Provides Updates on RoHS, REACH Directives
Fern Abrams, director of regulatory affairs and government relations at IPC, discusses with I-Connect007's Stephen Las Marias the latest updates on the changes happening in the RoHS and REACH directives this year, as well as IPC's new initiatives and advocacies.
Book Review: Meetings That Get Results
In this short but amazing book, Brian Tracy covers all types of meetings, from the large training sessions to the one-on-ones. He even describes how you should be sitting when having a one-on-one meeting (each of you at a corner of the table), how to get your point across, and how to listen.
Fire Retardancy: What, Why, and How
This article takes a critical look at all aspects of fire retardancy, starting with the need for fire safety, the function of a flame retardant, the reactive and additive flame retardant classes, major flame retardant compounds, toxicology and environmental impact of retardants--most especially Tetrabromobisphenol-A, which is the most widely used flame retardant in PCB materials--as well as European legislative directives.
Aluminum Base Circuit Technology: Structures and Manufacturing Methods
Aluminum is an attractive material for use in the manufacturing of electronic assemblies due to its low cost, good thermal properties, and stability. But due to its innate thermal spreading ability, it's not easily used when solder is required to make interconnections to components. This article describes ways to manufacture electronic assemblies using aluminum as a base and eschewing the use of solder.
Sustainability: What and Why?
Joe Fjelstad writes, "The resources of our planet are limited and thus are diminishing as we continue to unleash and ramp-up a seemingly never-ending flow of products to both serve and amuse us with output of the global electronics industry likely to be nearing the top of the list of 'offenders.' In that regard, we are becoming victims of our own success, to one degree or another."
