Mechanical circuit board prototyping is not a new concept. There are several systems on the market that do this relatively well, but they cost upwards of $20K. We felt that a system that significantly improved on the existing technology could be offered for around $10K. Through extensive research and development, MicroKinetics was able to develop a system that is more precise and more convenient to use at a significantly lower cost. The SuperScribe Circuit Board Prototyping System was developed to eliminate set screw tool holding, solenoid controlled Z axis problems and easily misaligned machines. Additionally, we designed and integrated a chip transport vacuum system that is very effective!

The SuperScribetm model 1812 is a complete, desktop circuit board prototyping system capable of producing single and double sided boards using standard Gerbertm, Excellontm, and HPGLtm data. The system's high resolution and repeatability allows quick, precise prototyping of high density and surface mount circuit boards. The SuperScribe system features a variable speed collet spindle which accepts widely available standard 1/8” diameter cutters and drills. The software controlled, stepper motor actuated Z-axis provides precision depth and feed-rate control for hands-off multiple pass milling, routing, and engraving. Use of 3/4" thick, high precision base plate and dual, high accuracy ball bearing components makes the Model 1812 a superb performer in rigidity, precision, and accuracy.

SOFTWARE:
The SuperScribe circuit board prototyping system includes PCB design and prototyping software, which combines both schematic capture and circuit board layout in one powerful, easy-to-use package. Features transparent import/export filters to enable you to effortlessly read and write files from ORCADtm, TANGOtm, PROTELtm, and AutoCADtm as well as Gerber, HPGL, and DMPLtm files. Intelligent CAM functions automatically optimize and route isolation paths for milling around all pads and traces to quickly produce accurate, high quality prototype circuit boards. Also included is the SuperScribe engraving software which interprets the HPGL plot file and runs the machine. It is compatible with hundreds of programs including AutoCAD, CIRCAD, and InstaCAMtm. Features include pull-down menus and the ability to preview, scale, and offset the board before engraving. Layers are defined by pen colors which are used to select different speeds and depths of cuts. Up to 8 speeds and depths can be used simultaneously. For mechanically etching circuits, you set it for a single pass, but when cutting a deep profile in a metal part you will need to set it to run multiple passes. This will automatically divide the final depth into a number of passes determined by a programmable maximum depth per pass. The stepper motor actuated Z-axis features separate programmable up/down feed rates to assure maximum tool life and minimum production time. Other software features include semi-automatic tool change, interactive keyboard jogging, programmable origin/start position, and contour routing with true circular interpolation.
