SMTnet's OnBoard Forum to Feature Bob Willis
July 20, 2000 12:00 to 5:00PM Eastern Time
So just what is the OnBoard Forum? Each month we will bring prominent professionals in the electronics manufacturing industry to SMTnet to discuss timely issues affecting the industry. We anticipate thought-provoking discussions, and expect issues raised during OnBoard Forums to reverberate in the Electronics Forums once the interview session has concluded (just the type of food-for-thought exchanges SMTneter's have been looking for!).
Our next OnBoard Forum will feature Bob Willis, who currently operates Electronic Presentation Services, a training and consultancy business based in England and operating world wide. EPS produces and sells one of the widest selections of training videos and CD-ROMs for electronics manufacturing. He has worked with the GEC Technical Directorate as Surface Mount Co-Ordinator for both the Marconi and GEC group of companies and prior to that he was Senior Process Control Engineer with Marconi Communication Systems. As Technical Director for the SMART Group, the European Surface Mount Trade Association, Mr. Willis has produced and donated three reports to be sold by the SMTA, with all proceeds going to the Charles Hutchins Educational Grant.
Topics open for our OnBoard discussion include Pin In Hole Reflow, his new process of Simultaneous Double Sided Reflow Assembly, or any process related subject.
Chip Scale Package: Design, Materials, Process, Reliability, and Applications by John H. Lau, Ricky S. Lee
Reviewed by Wolfgang Busko First when I entered the electronic business, I learned what was state of the art, huge parts, all discrete, serving as additional heaters in long cold winters, glowing lightshows inside furniture-like wooden boxes that should match with what was considered to be the "New Gem�tlichkeit" in the field of interior design. Not so much has changed except for the use of PCBs and automation in the assembly process, all parts still visible and manageable ...
Photonic Soldering for Rework Applications byErick Russell, Vision Inspection Technology Continually shrinking package sizes, reduction of pitch, and reduction of clearance areas available around components has made it increasingly difficult to rework and repair printed circuit board assemblies. Hand held electronics push the envelope of the board design criteria when rework is considered using traditional techniques of convection thermal process development. Photonic soldering for rework applications shows advantages using inventive control tools and powerful computer interface for programming. Improving process requirements and the increasing complexity of printed circuit boards has prompted the development and release of a new technology for selective soldering and rework. By precisely controlling and monitoring the surface temperature of a component using a Pyrometer, a YAG Laser may be focused and controlled in a precise pattern to reflow the solder of surface mount components. This technology reduces the amount of tooling required for soldering different components, prevents the reflow of adjacent components, and increases the speed of which rework may be carried out...
Tell Us What You Think We have held two OnBoard Forums so far, and we want to know what you think about the concept and presentation. Also, we are looking for suggestions regarding future moderators. If there is an industry leader you would like to have a question and answer session with, or if you just have thoughts about the OnBoard Forum itself, please send your comments to SMTnet. SMTnet is your site and your ideas drive its development and evolution.
Publish Your Papers and Promote Your Company As SMTnet prepares for the next issue of the SMT Express, we are looking to our readers for articles and papers to feature. Submissions will be accepted any time for future issues. If you have anything you wish to offer, such as papers you have written, book reviews, anecdotes, commentaries, or anything we haven't thought of, please send it to SMTnet. Also, please read the submission guidelines.
The SMT Express is sent to thousands of electronics manufacturing professionals worldwide each month. This is a great opportunity to promote yourself and/or your company for free. In addition, a complete archive of past issues is avaiable at SMTnet.com, so your work will continue to be read long after the newsletter is released.
SMTnet is the most informative electronics industry resource on the Internet. New content is constantly being added, so we provide you with this content report to keep you informed of our progress since the last issue of this newsletter.
Search or browse the sections below for topics of interest to you.
The SMT Express is a periodical featuring assembly solutions from your peers and vendors. We, at SMTnet.com, have designed this newsletter to bring useful information to the mailboxes of electronics manufacturing professionals.
To help us provide you with useful and relevant information, we need your feedback, suggestions, complaints, and compliments. We also want your articles and technical papers. Please read the submission guidelines and Contact Us regarding article and news submissions.
- Thanks in advance
