Q: The problem with pcb manufacturers is it only becomes cost effective if you do multiple boards of the same type. Small batches etching at home is more cost effective.
A: By the time you get all the materials, create a good 1:1 negative or positive film, etch the boards, and drill them, let alone deal with through holes, a commercial board service proves more economical and without the problems of safe and legal chemical disposal. I have etched boards with a commercial UV-sensitive film and the results were OK, but not great. Maybe the process has gotten simpler and the photo-sensitive films better, but even for small hobby projects it's a pain.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
