Latest Patents
Duffy holds a patent for a "Hole cleaning process for printed circuit boards using permanganate." This improved process effectively removes resin smeared on the interior wall of a hole in a resinous substrate. The method involves contacting the substrate with an alkaline permanganate treating solution at a pH between about 11 and 13, along with an elevated temperature for a sufficient time to eliminate the resin smear. Following this, the process neutralizes manganese residue and uses an alkaline hydroxide etchant to remove any remaining residue. This innovative technique not only enhances the efficiency of electroless copper deposition but also improves the bond between copper and the hole wall.
