English to German translations [PRO] Tech/Engineering - Chemistry; Chem Sci/Eng | | English term or phrase: copper capture pads | | The board 224 is drilled for via connection (Fig. 8b) and the holes 232 are plated and filled with copper 234, as by a pattern plating process (Fig. 8c). Excess copper 236 extending from the vias is polished (Fig. 8d) and one external metal layer 230 is patterned with photoresist. The external metal layer 230 is etched to create so-called “capture pads” 238 (Fig. 8e). The surface of PWB 224 and ****copper capture pads**** 238 are coated with dielectric material 240, preferably polymeric dielectric material as described above, and this material is then etched back until the capture pads are exposed (Fig. 8f). At this stage, the PWB is ready to serve as a base for the process described in Figs. 4a to 4k, and a first layer of titanium followed by a layer of tantalum followed by a first layer of aluminum conductors can be formed thereon. |
