Atotech to Demo Spherolyte CU UF3 for Fine Line RDL at ECTC 2018


Reading time ( words)

Atotech will be exhibiting at the Electronics Components and Technology Conference (ECTC) 2018. As a gold sponsor, Atotech will participate with two presentations and a booth, highlighting its latest solutions for flexible electronics as well as fan-out wafer-level and fan-out panel-level packaging. The 68th ECTC will be held from May 29 to June 1, 2018, at the Sheraton San Diego Hotel and Marina in San Diego, California. Atotech’s international experts and specialists can be found at booth 207.

On Wednesday, May 30, from 8:00 – 8:25 am, Tobias Bernhard, Scientist for desmear and metallization at Atotech Deutschland GmbH, will talk about the “In-situ stress determination of electroless copper on PCB-relevant substrates”. The presentation is part of Session I on “Flexible Electronics, Substrates for High Frequency Applications” and takes place in Room Harbor Island 1. In his presentation, Tobias Bernhard will present the stress evolution of electroless Cu during and after deposition on ABF, Polyimide and on Ni-Fe in combination with Ni-containing and Ni-free commercial available electroless Cu baths.  

On Friday, June 1, from 10:50 – 11:15 am, Ralf Schmidt, Team Manager R&D for semiconductor technology at Atotech Deutschland GmbH, will present the “Optimization of electrodeposited copper for sub 5 µm L/S RDL lines by plating additives”. As part of Session 26 on “Wafer-Level Packaging Fan-In and Fan-Out Key Developments,” the presentation will be held in Room Harbor Island 2. In his presentation, Ralf Schmidt will present Atotech’s Spherolyte Cu UF3 process, which fulfills the requirements of current fine line RDL. This high-purity ECD Cu process is a three additive system designed for plating sub 5 µm Cu lines and large Cu pads while simultaneously enabling via filling.

The ECTC is one of the premier international events bringing together the best in packaging, components and microelectronic systems science, technology and education in an environment of cooperation and technical exchange. As such, it is the perfect place for companies like Atotech to present and exhibit their innovative systems and product solutions. The 2018 ECTC will feature, among others, about 40 technical sessions, 16 professional development courses, and a technology corner for exhibitors. 

Visitors to the show are invited to join Atotech’s presentations or pass by booth 207 during the ECTC show. At the show, visitors can find out more about Atotech’s market-leading manufacturing tools, such as MultiPlate® - a systems solution for double sided (DS) ECD on wafer and DS electrolytic plating on glass panels. Atotech will also present its applications for the HDI, package substrate, semiconductor, flex/rigid-flex, PCB and IC leadframes markets. Local and international specialists will be on site to discuss any question or inquiry.

PCB Material Toolbox for Today's 3G & 4G Networks and Future High-Speed Needs in 5G

06/21/2018 | Stig Källman, ERICSSON with Happy Holden, I-CONNECT007
The material toolbox idea first came up when I saw the IPC appendix list for standard 1-ply stack-ups. The idea is to make a very simple bill of materials, specifications and notes, and possibly use the same prepreg/resin in the laminate and in the core.
