Message-ID: Date: 22 Jan 91 19:13:12 GMT Organization: Rutgers Univ., New Brunswick, N.J. Lines: 32 Recently I got some information in the mail from HTE Corporation in San Diego. They sell a pcb prototyping system that enables you to make single, double and multilayer printed circuit boards. It consists mainly of a plotter that draws the traces on the pcb with an etch resistant ink. The plotter also has a drilling attachment to drill the holes and vias. The system also includes a tank for the sodium persulphate etchant. The boards it produces are not plated thru holes. So soldering must be done on each side of the board. How reliable and how inconvenient is this? Multilayer boards are made by first making a double sided board and then making layers on flexible laminates and then soldering the layers to one side of the double sided board. I would appreciate if any fellow sci.electronics netters who are experienced in making pcbs would comment on this system. Of course, I would like to hear from anyone who has the HTE system. But this is a new product and I'm not sure that anyone who owns a system will have access to the net. Any comments posted to this newsgroup or emailed to me will be greatly appreciated.
