Fremont, CA (PRWEB) July 3, 2006
SchmartBoard, the developer of a new technology that has significantly simplified the creation of electronic circuits for hobbyists, education and industry, has announced that it has signed German distributor ELV Elektronik AG to supply Germany with the full line of RoHS compliant SchmartBoard products.
Most people who design electronic circuits do not have the skills to hand-solder surface mount components. SchmartBoard|ez was developed as a solution for this problem. What once could only be achieved by technicians with many hours of experience, can now be done by anyone. A ten year old who has never held a soldering iron, can now hand solder a .4mm IC or a BGA (Ball Grid Array) effortlessly and flawlessly.
According to Neal Greenberg, SchmartBoard’s VP Sales and Marketing, “We have received numerous e-mails from people in Germany who have want access to SchmartBoard’s technology. We are happy to finally find a partner to make Schmartboard available to people in Germany and support industry, academia, and individual hobbyists there.”
Ralph Landwehr, Head of Product Management at ELV, says “SchmartBoard is a perfect solution for our professionals and hobbyists who are used to working with a soldering iron. Now they can take the advantage of using the newest solutions in ICs that often are only available in SMD – type housings”.
SchmartBoards are used by industry professionals to prototype circuits, universities for R&D and as teaching tools, and by individual hobbyists involved in electronics, robotics, ham radio and other areas.
About SchmartBOARD (http://www.schmartboard.com)
SchmartBOARDTM is committed to helping engineers, students and hobbyists develop electronic circuits faster, easier, and less expensively than previously possible. Schmartboard’s patent pending Electronic Circuit Building Blocks makes this possible. More information about Schmartboard can be found at http://www.schmartboard.com
About ELV Elektronik AG (http://www.elv.de)
ELV is one of the biggest mail-order companies for every type of electronic part in Germany and Europe. The 700 page main catalogue, with a circulation of more than 500.000 pieces per year, is standard literature for technical enthusiast consumers.”
