    摘要: Low tortuosity porous polymer sheets (25 to 2000 pores per square millimeter) with metal plated in the pores so as to project beyond sheet surfaces provide uniaxial electrical interconnects. A first "flash" layer of metal is electrolessly plated in the pores and the "flash" coating of metal is then removed from the sheet surface to isolate the pores electrically from one another. Further plating is then applied only to the already plated pore surfaces to fill the pores and/or project beyond the sheet surface. Solder may fill the plated pores. Polymer layers may be removed from the sheets to expose the metal in the pores. The articles are useful in making electrical connections to the contact pads of microcircuits during testing and assembly into electronic devices.

    摘要: A plateable toner which can be effectively employed in plateable toner technology comprises a shell and core arrangement where the core is a toner particle and the shell is an effective amount of at least one catalyzing and/or activating compound for electroless plating and at least one binding and/or sensitizing compound. The toner core can comprise a commercially available OEM toner powder, a toner core having properties selected for PTT produced by techniques employed in OEM toner production or a spray dried toner core.
