Atotech

One of the world's leading suppliers of integrated production systems, chemistry, equipment, know-how and service for electroplating, semiconductor and printed circuit board manufacturing.

Manufacturer of Assembly Material, Manufacturer of Components, Components/Substrates

Atotech was founded in 1993, when the Elf Atochem Group merged its M&T Harshaw operations with Schering Electroplating Division having a deep history in electroplating dating back to 1901. Today, Atotech is a direct subsidiary of the world's fifths-largest oil and gas company Total, created from the merger of TotalFina and Elf Aquitaine in 2000.

As the fifth largest chemical company, Total holds leading positions in Europe and throughout the world in each of the following markets: Petrochemicals, Fertilizers, Specialty Chemicals for consumer as well as industrial markets. Being part of the chemical branch of the oil and gas group Total, Atotech has access to substantial resources and benefits from production, R&D and distribution synergies within this major company.

Next to the core business units: GMF (General Metal Finishing) and Electronics (Printed Circuit Board Production), additional business units such as Electronics Materials and Wafer play an increasingly important role for the future growth of Atotech and its customers.

High Throw Electroless Copper - Enabling new Opportunities for IC Substrates and HDI Manufacturing

Apr 20, 2017 | Tobias Sponholz, Lars-Eric Pribyl, Frank Brüning, Robin Taylor

The one constant in electronics manufacturing is change. Moore's Law, which successfully predicted a rate of change at which transistor counts doubled on Integrated Circuits (ICs) at lower cost for decades, is ceding to be an appropriate prediction tool. Increasing technical and economic requirements, deriving from the semiconductor environment, are cascaded down to the printed circuit and in particular to the IC substrate manufacturers. This is both a challenge and an opportunity for IC Substrate manufacturers, when dealing with the demands of the packaging market. (...)

This paper introduces two new electroless copper baths developed for IC substrates manufacturing based on Semi Additive Process (SAP) technology (hereafter referred to as E'less Copper IC) and HDI production (hereafter referred to as E'less Copper HDI) and optimized for high throw into BMVs. An introduction to reliable throwing power measurement methods based on scanning electron microscope (SEM) is given, followed by a compilation and discussion of key performance criteria for each application, namely throwing power, copper adhesion on the substrate, dry film adhesion and reliability....

Effect of Process Variations on Solder Joint Reliability for Nickel-based Surface Finishes

Nov 06, 2014 | Hugh Roberts, Sven Lamprecht, Gustavo Ramos, Christian Sebald

This paper summarizes the results of recent investigations to examine the effect of electroless nickel process variations with respect to Pb-free (Sn-3.0Ag-0.5Cu) solder connections. These investigations included both ENIG and NiPd as surface finishes intended for second level interconnects in BGA applications. Process variations that are suspected to weaken solder joint reliability, including treatment time and pH, were used to achieve differences in nickel layer composition. Immersion gold deposits were also varied, but were directly dependent upon the plated nickel characteristics. In contrast to gold, different electroless palladium thicknesses were independently achieved by treatment time adjustments....

Wire Bonding and Soldering on Enepig and Enep Surface Finishes with Pure Pd-Layers

Oct 11, 2012 | Mustafa Özkök, Joe McGurran, Dieter Metzger, Hugh Roberts

First published in the 2012 IPC APEX EXPO technical conference proceedings. This paper shows the benefits by using a pure palladium Layer in the ENEPIG (Electroless Nickel, Electroless Palladium, Immersion Gold) and ENEP (Electroless Nickel, Electroless P...

Corrosion Resistance of Different PCB Surface Finishes in Harsh Environments

Aug 09, 2012 | Mustafa Özkök, Joe McGurran, Hugh Roberts. Kenneth Lee, Guenter Heinz

First published in the 2012 IPC APEX EXPO technical conference proceedings. Corrosion resistance is becoming one of the most important topics in the electronics industry. Corrosion results in field failures and huge losses, which annually total several bi...
