Bordering takes place at the same time to remove the copper and epoxide projections from | MULTILAYER CIRCUIT BOARDS SERVICES | the edges of the Panel and to achieve its specified dimensions Of course the layer recognition routine takes longer than a conventional CNC procedure, but | MULTILAYER CIRCUIT BOARDS SERVICES | it is not presumptuous to claim that immediately after pressing the multi layer has the quality of a plated throug circuit The art of viewing | MULTILAYER CIRCUIT BOARDS SERVICES | chicken eggs clearly. Although the fundamental idea appears ingeniously simple, the most sophisticated German technology was necessary to carry it out. It was extremely complicated | MULTILAYER CIRCUIT BOARDS SERVICES | to develop a camera system which can not only see all spatial levels equally clearly, but is also able to see the lines located at | MULTILAYER CIRCUIT BOARDS SERVICES | different distances, and to measure them. (To give some idea of the difficulty, one could compare viewing a boiled egg from above and trying to | MULTILAYER CIRCUIT BOARDS SERVICES | see the egg cup as well as the tip of the egg clearly). The Frauenhofer Institute’s achievements in ...
