Schlötter focuses on energy saving at SurfaceTechnology 2022

SurfaceTechnology Germany is back at last! After the cancellation of the trade fair in 2020 due to Corona, the industry is looking forward to SurfaceTechnology 2022, which will take place in Stuttgart from 21-23 June 2022. Around 220 national and international exhibitors will present the most important trends in surface technology at the trade fair. SurfaceTechnology Germany has a fixed place in the trade fair calendar of Dr.-Ing. Max Schlötter GmbH & Co. KG. As a solution provider, Schlötter will be presenting holistic solutions for electroplating chemistry, plant technology and service at the trade fair (Hall 1, Stand C28). In 2022, Schlötter will also celebrate its 110th anniversary; the company was founded by Dr.-Ing. Max Schlötter in Leipzig in 1912.

Schlötter’s product highlights at SurfaceTechnology are: The patented alkaline zinc-nickel alloy baths of the SLOTOLOY ZN VX product family, SLOTOLOY ZN 210 VX (barrel application) and SLOTOLOY ZN 80 VX (rack application), which have consistently proven themselves in practice. A special anode largely prevents the formation of cyanides during deposition of the zinc-nickel layer. A low-cost alternative to membrane systems, Schlötter’s SLOTOLOY ZN VX technology has proven to reduce consumption of chemistry, nickel and energy during deposition and cooling. The overall energy required for coating and cooling is reduced by up to 35%. Together with Passivation SLOTOPAS ZNT 80 and Sealant GM 2450 , SLOTOLOY ZN VX processes form a perfect trio in terms of corrosion protection and tribological properties. Sealant GM 2450, which will also be presented in the expert forum, meets the new standards for lubricant-containing sealants for fasteners. Sealant GM 2450 fulfils the requirements of the specifications VW 01131 and MBN 10544.

Together with iChemAnalytics, Schlötter will also present a new type of test stand at their booth, which enables in-process monitoring of hydrogen absorption. Within a test period of 60 – 120 seconds, it is possible to obtain reliable key figures and process monitoring with regard to hydrogen embrittlement. Among others, it is possible to monitor hydrogen evolution in pre-treatment processes. With the pickle degreaser SLOTOCLEAN BEF 1790, Schlötter has developed a product that effectively reduces the absorption of hydrogen in the base material. This makes it possible to reduce heat treatment steps such as tempering.

Schlötter is also represented with two talks in the expert forum: In her presentation “No fear of hydrogen embrittlement – an approach for solution” (Wednesday, 22 June, from 11.00 – 11.20 a.m.), Vera Lipp, R&D team leader for PCB and electronics, will be looking at quality assurance in the surface treatment of high-strength fasteners. Oliver Daub from the R&D team for cathodic corrosion protection will present SLOTOFIN GM 2450, a“High-performance sealing for connecting elements” that meets the highest requirements for corrosion protection and friction coefficient (Wednesday, 22 June, 3.20 – 3.40 p.m.). Both talks will be translated into English

We look forward to welcoming you on our stand in Hall 1, C28.

Schlötter is awarded TOP 100 seal

Award-winning innovative strength: Dr.-Ing. Max Schlötter GmbH & Co. KG from Geislingen has been awarded the TOP 100 seal 2021. This award honours particularly innovative medium-sized companies – and this is now the 28th time. Schlötter had previously proven its innovative strength in a scientific selection process.

On behalf of compamedia, the organiser of the TOP 100 innovation competition, innovation researcher Prof. Dr. Nikolaus Franke and his team examined Schlötter’s innovative strength. The researchers used around 120 test criteria from five categories as a basis: Innovation-promoting top management, innovation climate, innovative processes and organisation, external orientation/open innovation and innovation success. Schlötter participated in the innovation competition for the first time and was successful right from the start.

Innovation has a long tradition at Schlötter. After all, the company was founded in 1912 as an electrochemical research laboratory. Even today, around 25% of all employees work on the development of new electroplating processes at the headquarters in Geislingen. Schlötter’s commitment to research & development can also be measured by the number of patents from the fields of chemistry and plant technology that are filed each year. From 2018 to 2020, for example, 22 national and international patents were filed by Schlötter employees and one national and 9 international patents were granted in the last 2 years, including patent EP 3481976 for the SLOTOLOY ZN VX technology, a particularly resource-efficient process for the deposition of alkaline zinc-nickel, which was awarded the Innovation Prize of the State of Baden-Württemberg in 2018.

“We are very pleased to receive this award! After all, it is a visible sign of our successful research and development activities and a very special award for the efforts of our employees. In keeping with the tradition of our company founder Max Schlötter: “Trusting in the old to create the new”, we strive every day to make a visible contribution to the technological leadership of our customers. The protection of our natural resources is particularly close to our hearts. For this reason, many of our new projects deal with the challenging issues of data transmission, the mobility of tomorrow, or the closing of material cycles. All of this is only possible with our great team from all areas of the company!”, says Dr. Michael Zöllinger, Managing Director of Schlötter.

Prof. Dr. Nikolaus Franke, the scientific director of TOP 100, is impressed by the award-winning medium-sized companies. “The TOP 100 companies have consistently oriented themselves towards being as innovative as possible,” he states.

Schlötter at the TPCA 2020

While large parts of Europe are back in lockdown mode with public events and trade fairs being cancelled, economic life in Asia continues. TPCA 2020, one of the most important trade fairs for the PCB industry worldwide, took place as planned in Taipei from October 21 to 23, 2020. With around 31,000 visitors, the number of visitors was only 1.7% lower than in the previous year despite Corona. Dr.-Max Schlötter GmbH & Co. KG was again present at the TPCA. Together with AGES, their long-standing sales and development partner in Taiwan, Schlötter presented viafilling and TH-plating copper electrolytes and direct metallization processes from the current product range. These include the superfilling processes SLOTOCOUP SF 40 for 5G (3 in 1 solution for inner layers, layer build-up and outer layers), SLOTOCOUP SF 50 for 5G (3 in 1 solution for inner layers, layer build-up and outer layers) and SLOTOCOUP 1960 (for automotive PCBs) as well as the direct metallization processes SLOTOSIT PCB 3500 (graphite based), SLOTOSIT PCB 3700 (graphene oxide metallization) and SLOTOSIT 3800 (metallization by means of sulfonation).

Innovative: The glass metallization SLOTOSIT SEA 2800

At the trade fair, the SLOTOSIT SEA 2800 glass metallization process was presented for the first time. This process is suitable for metallizing PCB substrates made of glass, display glass or through glass vias (TGV) and blind glass vias (BGV), for which sputtering processes have been largely used so far. A promising field of application for SLOTOSIT SEA 2800 are displays manufactured with Micro LED technology. Devices with Micro LED technology are not yet available for the broad consumer market. But they are expected to reach market maturity soon. The ever increasing use of devices such as smart watches, smartphones or tablets, pushes the demand for powerful and innovative displays which present a variety of information on a small space. SLOTOSIT SEA 2800 is hydrofluoric acid-free, easy to control and enables excellent adhesion of the metal layer to glass. The process allows high layer thicknesses to be deposited without delamination.

Matthias Hampel, PCB Technology Manager of Schlötter, drew a positive conclusion: “Our new glass metallization SLOTOSIT SEA 2800 met with great interest. The customers and visitors to the booth were also very positive about the fact that I attended TPCA despite the corona crisis.”

Schlötter’s first virtual fair
has generated a strong interest

How to get close to your customers in times of social distancing: After the cancellation of the Surface Technology Germany in Stuttgart due to Corona, Dr.-Ing. Max Schlötter GmbH & Co. KG decided to organise a virtual trade fair instead from 16-18 June 2020 to inform its customers and sales partners about new products. During a tour of the virtual exhibition stand visitors could look at various digital exhibits which were just a mouse-click away. The exhibits included Copper SLOTOCOUP PRT 2200, a reverse pulse plating process, which was developed for through-hole plating of printed circuit boards with very high aspect ratios which are used, eg., for manufacturing server boards, Pickle Degreaser SLOTOCLEAN BEF 1790 which reduces the risk of production-related hydrogen embrittlement, and various processes for direct metallisation of plastics.

Schlötter’s plant engineering division exhibited a new high-power contact and an optimised zinc dissolving station (also filed for patent). For the first time, Schlötter also presented Schlötter Smart Services, the company’s new digital solution for the Internet of Things (IoT). Schlötter Smart Services consist of two main features: online plant monitoring and process monitoring via a web-based application. In doing this, important parameters such as the plant output or the temperature and pH value of the electrolytes being used can be monitored automatically.

The Italian company Italtecno, with whom Schlötter has recently concluded a cooperation agreement, was also present at the virtual trade fair.

Thomas Haberfellner, Head of Sales and Service at Schlötter, drew a positive conclusion: “Overall, we were very pleased with the attendance, as we were able to welcome many hundreds of visitors at our booth. Our webinar lectures, which were a first for Schlötter, were particularly popular. The webinars resulted in many interesting discussions and in-depth talks as well as appointments for individual webinars”.

Schlötter is granted patent
for SLOTOLOY ZN VX technology

“Method for the galvanic deposition of zinf and zinc alloy layers from an alkaline coating bath with reduced degradation of organic bath additives” – this is the title of European patent EP 3481976, which was granted to Dr.-Ing. Max Schlötter GmbH & Co. KG on 15 April 2020.This somewhat lengthy title refers to Schlötter’s SLOTOLOY ZN VX technology, which was awarded the Innovation Prize of the state of Baden-Württemberg in 2018. The SLOTOLOY ZN VX technology is the basis for two zinc-nickel alloy baths SLOTOLOY ZN 80 VX (for rack applications) and SLOTOLOY ZN 210 VX (for barrel applications). Both electrolytes feature a significantly reduced formation of cyanides and a lower consumption of organic additives compared to conventional alkaline zinc-nickel electrolytes. At the same time, the bath voltage is significantly reduced and energy efficiency is significantly increased.

The VX systems offer  following advantages:

  • Efficient use of resources: The overall consumption of chemicals is lower, since significantly less organics are degraded. Due to the lower cyanide content of the electrolyte, a lower nickel concentraction is required. Less raw materials are required to operate the electrolyte, which has a positive effect on consumption costs. Due to the lower bath voltage and less needs forcooling, the overall power consumption is reduced by up to 30%.
  • Higher productivity: The current efficiency increases by 5-10% for barrel applications and by approx. 5-7% fro rack applications. Due to the higher current yield, the deposition rate is simultaneously increased by approx. 5-20%, thus the output of electroplating plants can be increased by up to 30% (for barrel applications).
  • Strengthening of environmental and climate protection: The significant energy savings in plating, the faster deposition rate and the savings in organic additives not only lead to an increase in productivity, but also to a significant reduction in cyanide and wastewater volume per plated parts and a reduction in energy and chemical consumption in wastewater treatment. The new process thus represents an active contribution to environmental and climate protection.

Meanwhile, both SLOTOLOY ZN VX 80 and SLOTOLOY ZN VX 210 have performed tremendously well in practice for about three years and are in use worldwide.
