The present invention provides an improved cardcage design. The virus is selected from the group consisting of a Newcastle disease virus, a measles virus, a vesicular stomatitis virus, an influenza virus, a Sindbis virus, a picornavirus, and a myxoma virus. The plasma container is disposed at a position adjacent to the partition member to receive a portion of the plasma. Unfortunately, core-etched foils don’t work well in multiple-anode capacitors, and tunnel-etched foils are quite brittle and tend to break when making some common types of capacitors. Since the positioning of the component is made using exact reference features on the substrate, the whole soldering process results in a highly accurate lateral position of the soldered component.
