Patent DE-4040226-A1 (DE)
Inventor: STADTMUELLER LUDWIG
IPC: H05K3/42
Filed: 1990-12-15
Abstract: A process for producing through hole plated or multilayer printed circuit boards combines two processes known in the art. The first process cleans the contacting through holes by soaking (1), rinsing (2) and oxidizing with a solution of permanganate (3). The known process further comprises, after an additional rinsing step, a so-called decontamination step followed by another rinsing step; these last steps are dispensed with however, according to the invention. The second known process plates without current the outer surfaces of the through holes with an electroconductive layer, by means of a conditioning or soaking step, a rinsing step, an oxidizing step with a solution of permanganate (9), another rinsing step (10) and the precipitation of monomers contained in a solution (11), which are then polymerized (12), forming an electroconductive layer. After an additional rinsing or etching step (13), the printed circuit or multilayer boards are subjected to further manufacturing processes which do not fall in the scope of the invention. The disclosed process allows the initial conditioning or soaking step of the last named, known process, as well as the following rinsing step, to be dispensed with, thanks to the combination with the first named process. In total, at least two processing steps, during which a processing fluid is applied to the printed circuit or multilayer boards, as well as the corresponding rinsing steps are dispensed with.
