Publication number: 20190279942Abstract: The present disclosure is directed to a lead frame design that includes a copper alloy base material coated with an electroplated copper layer, a precious metal, and an adhesion promotion compound. The layers compensate for scratches or surface irregularities in the base material while promoting adhesion from the lead frame to the conductive connectors, and to the encapsulant by coupling them to different layers of a multilayer coating on the lead frame. The first layer of the multilayer coating is a soft electroplated copper to smooth the surface of the base material. The second layer of the multilayer coating is a thin precious metal to facilitate a mechanical coupling between leads of the lead frame and conductive connectors. The third layer of the multilayer coating is the adhesion promotion compound for facilitating a mechanical coupling to an encapsulant around the lead frame.Type: ApplicationFiled: March 11, 2019Publication date: September 12, 2019Inventors: Paolo Crema, Jürgen Barthelmes, Din-Ghee Neoh

Patent number: 9057145Abstract: A method for electrodepositing a metal layer from an electrolytic bath is described, wherein the concentrations of at least two components of the electrolytic bath are monitored by carrying out the following steps: (a) a sample is taken from the electrolytic bath; (b) the sample is supplied to a column for solid phase extraction, which contains a solid sorbent material; (c) the column is subjected to a washing procedure with a first eluent, wherein the at least two components remain on the column, and undesired components are eluted from the column; (d) the at least two components are eluted from the column by a second eluent; (e) the concentrations of the at least two components in the eluate obtained in step (d) are determined without separating the components from each other. In this method the use of poly(divinyl benzene-co-N-vinyl pyrrolidone) for solid phase extraction is particularly advantageous.Type: GrantFiled: December 10, 2007Date of Patent: June 16, 2015Assignee: Atotech Deutschland GmbHInventors: Jürgen Barthelmes, Robert Rüther, Florence Lagorce-Broc, Olaf Kurtz, Oleg Sprenger, Marta Sainz-Vila, Thomas Moritz, Josef Gaida
