... in both vertical and horizontal process equipment, the versatile system yields total process cost reduction Panel Plating a Flash of Copper The panels are | CIRCUIT BOARDS SUPPLIERS | online in a wet state transferred to our automatic electrolytic copper plating lines to get a flasch of copper.. The panels are attached to plating | CIRCUIT BOARDS SUPPLIERS | racks. When the racks are moved to the loading station, the system computer instructs the hoist to pick up the rack and begin the plating | CIRCUIT BOARDS SUPPLIERS | cycle. The copper plating time is approximately one hour. Electrolytic copper of minimum thickness 12 microns is deposited on the surface of the panel and | CIRCUIT BOARDS SUPPLIERS | on the walls of the drilled holes. This is achieved by applying an electric current to a cell comprising the panel (the cathode) and a | CIRCUIT BOARDS SUPPLIERS | set of copper bars (the anodes) suspended in a conducting medium (the electrolyte). A plating history log is maintained on the shop floor control computer | CIRCUIT BOARDS SUPPLIERS | which assists the operator in making minor adjustments to the plating current. Finally, the panels are ...

... which drillings or milling should be plated through or not plated through. 2.) The dimensions on separately enclosed measure plans do not agree with | CIRCUIT BOARDS SUPPLIERS | the outline of the gerberdata. 3.) Data concerning the outer contour are missing. 4.) The aperturetable or the explanation of the symbolism of the aperturetable | CIRCUIT BOARDS SUPPLIERS | is missing. 5.) By production of printed circuit boards in a v- scored array sub panel are conductive strips or pads placed in such a | CIRCUIT BOARDS SUPPLIERS | way that the minimal edge distance of 0.5 mm is not considered. 6.) Exact tool-size`s for the drill-files are missing. 7.) The indication of slot-milling`s, | CIRCUIT BOARDS SUPPLIERS | wheather the dimension`s or the outline is to be understood inclusive or plus the milling- radius. 8.) The signature (serves as an idiot key) in | CIRCUIT BOARDS SUPPLIERS | a conductive-outer layer is missing, in order to be able to recognize the opinion "reflected or not reflected". 9.) The minimum distance of 0.25 mm | CIRCUIT BOARDS SUPPLIERS | from conductive strips or pads to not plated through drills or milling is not considered. | ...
