Learn how to use advanced PCB surface treatment for best copper to copper and resist adhesion as well as nano-technology as final finish for soldering
4th September 2008. Solingen, Germany. Language: GERMAN
Cost-reduction in PCB fabrication without sacrificing quality.
Maastricht - The treatment of copper is a major mile stone when it comes to yield improvement and cost reduction. Managers often ignore this important step that helps to prevent defects.EIPC, in conjunction with KIV PCB ProfiChem GmbH in Solingen, Germany, are holding a Workshop during which the relevant processes are reviewed and how the copper treatment has to perform depending on the condition of the copper, the plating solution as well as the condition of the equipment. The event is also sponsored by Ormecon who will explaining future nano-finishes for PCBs.
The goal of the workshop is to demonstrate how to achieve optimum process stability in line with the highest possible process efficiency and yield.
Optimising copper treatment is important at the following stages:
-
Inner layer resist lamination
-
After etching and resist stripping to optimise AOI efficiency
-
Surface treatment before multilayer lamination
-
Pre-lamination cleaning of copper for plating resist
-
Pre-plate cleaning for best adhesion of metal to metal
-
Pre-lamination cleaning before solder mask coating
-
Cleaning after solder mask curing (bake) to remove residues that may impact the final finish like HASL / electroless Sn / ENIG
Learn the benefits of Nano-Finishes to improve solderability and yield in the soldering processes.
During the workshop, participants will learn how to set up copper activation processes based on the fabrication processes, the type of PCB that are to be manufactured and the equipment that is available to meet the key objective: “Cost reduction in PCB fabrication“
The morning will be devoted to various technical presentations on copper surface treatment at the Hotel Schloss Grünewald in Solingen-Gräfrath, and after lunch there will be practical demonstrations at the KIV PCB factory in Solingen.
