WERTHEIM, GERMANY – Ersa GmbH recently installed the 2,000th selective soldering machine of its bestseller VERSAFLOW 3/45 in Hungary. For the official handover of the anniversary machine to the EMS service provider Flex in Hungary, Ersa General Sales Manager Rainer Krauss traveled with a delegation to Zalaegerszeg at the beginning of March.

Also present were the Budapest-based sales partner Microsolder Kft., represented by its Managing Director Csaba Peto, and the responsible Ersa Area Sales Manager Tom Berx. The partnership between Flex Hungary and Ersa started in 2008 with a first selective soldering machine, followed by 25 more VERSAFLOW 3/45s to date. Tamás Börcz, General Manager of Flex in Zalaegerszeg said: “We have extremely diverse product portfolios with a wide range of sizes and components – requirements are constantly changing, and we have to respond quickly and adequately. We evaluated extensively and made a decision in favor of Ersa when it comes to selective soldering, as their soldering systems offer extremely flexible options for highest throughput and best quality.”

The great acceptance of the modular and expandable Ersa selective soldering machines around the world is due to their versatility. Mixed assemblies with THT components and SMD assembly on both sides can be optimally produced with it. In contrast to wave soldering, the heat input into the assembly is much lower and no solder masks are required. The solder masks used in wave soldering protect SMD components on the underside of the PCB from re-melting and rinsing when in contact with the solder wave. These are also required for very small production runs and must each be manufactured individually – this time and cost factor is eliminated with selective soldering.

Thanks to this technology, individual components of a board can be soldered with individual parameters, whereas under wave soldering, the temperature and wetting time in the solder wave must be selected for the entire assembly. Selectively soldered assemblies are also less likely to become contaminated, as only a few areas need to be soldered and come into contact with flux and solder. Selective soldering is unbeatable if, in addition to the top side of the assembly, the bottom side is also populated with SMDs (with a low proportion of THT components).

In addition to high-performance hardware, first-class service is also crucial for Flex Hungary. Commenting on the relationship, Ersa Sales Director Rainer Krauss said: “With our sales and service network, we are globally positioned and always close to our customers to provide the same level of quality in terms of hardware and service everywhere – at Flex Hungary, this is our sales partner Microsolder, who has supported us for many years in the integration and service of new and existing systems. We have enjoyed a successful partnership with Flex Hungary for 20 years, and we would like to continue this in the future.” Zoltán Tuboly, Manufacturing Engineering Manager at Flex Hungary echoes the sentiment adding: “I can only agree and thank the Ersa team for continued strong support over many years.”

MUENCHEN, GERMANY – Emitech, a company specializing in applied testing for product qualification in the automotive sector, has inaugurated its new vehicle test center in Montigny-le-Bretonneux, France. The EMC chamber is equipped with a complete EMC test system from Rohde & Schwarz including R&S BBA150, R&S BBA130 and R&S BBL200 broadband amplifiers, R&S ESW44 test receivers, R&S SMB100B RF signal generators and power meters. At the inauguration ceremony in March, Rohde & Schwarz also demonstrated its innovative solution for advanced driver assistance system (ADAS) testing.

Emitech's new test center is dedicated to electromagnetic compatibility tests for vehicles: two and three- wheelers, cars, trucks, tractors, construction machinery, etc. The reinforcement of a heavy load area supporting up to 40 t allows it to accommodate construction machinery as well as high-tonnage and high- volume equipment found in the defense, aeronautics, railways and nuclear power sectors and, by extension, industry. The center also has the largest and most recent Faraday cage built in France, which is used to perform electromagnetic compatibility tests to ensure that the equipment under test does not generate interference and is not itself disturbed by interference representative of the context in which it will be used.

The R&S BBA and R&S BBL amplifiers support the EMC tests at Emitech's test center. They are housed in several system racks and supply high-power RF signals to all transducers used in the conducted and radiated EMC test setups. More specifically, two racks for R&S BBL200 amplifiers and a 3 kW power class R&S BBA150 amplifier are installed below the chamber, which work together to create a high field strength from 9 kHz to 1 GHz. The amplifiers use one stripline antenna and two log-periodic antennas. Additionally, a mobile rack including 600 W/300 W power class R&S BBA130 amplifiers with one horn antenna is used inside the chamber for high field strength tests up to 6 GHz.

The R&S BBA amplifiers cover frequency bands up to 6 GHz. These amplifiers can be used for a variety of applications, including the various standards for EMS measurements. The R&S BBL200 liquid-cooled power amplifiers for high field strengths complement the test setup. These amplifiers are ideal for applications requiring high RF power in a frequency range from 9 kHz to 250 MHz. They are liquid-cooled, solid-state, highly rugged, quiet and efficient. Precise monitoring of all runtime parameters ensures maximum robustness and reliability. The amplifiers are designed for continuous operation and deliver constant power even under mismatch conditions.

This Rohde & Schwarz project for the French automotive market represents another benchmark EMC test solution.

CLINTON, NY – The next episode of Indium Corporation’s free webcast series EV InSIDER Live, titled e-Mobility Batteries: The Next Frontier of Sustainability and the Circular Economy, is set to premier on Thursday, May 11, at 11:30 a.m. EST.

EV InSIDER Live is co-hosted by Indium Corporation’s Global Head of e-Mobility and Infrastructure, Brian O’Leary, and Loren McDonald, EV consultant and CEO of EVAdoption. It is conducted in a candid and conversational format suitable for business executives, casual observers, and seasoned engineers alike.

The upcoming session, featuring special guest Oliver Gross, Global Director of Energy Services – Electrification and EV Operations at Stellantis, will explore a range of topics including:

• The role of automakers in the future, including the circular economy. Will automakers follow Tesla's lead and compete in both the electric vehicle and energy spaces? Gross will outline his idea for the Energy Internet of Things (EIoT), vehicle to grid opportunities, and the interplay with microgrids and virtual power plants.
• The latest developments in battery technology and chemistry that could significantly extend the life of EV batteries. Hosts will examine the likely “high/low” bi-furcation of battery chemistries for low-range and long-range EV applications. Which approach will win out in the end: recycling or repurposing batteries in second-life applications? How will bi-directional charging affect battery life? Is the 70%-80% energy capacity rule of thumb for EV end-of-life the right metric, or do we need to think differently about battery lifespans?
• How will government action impact supply chains? What effect will the recent Clean Vehicle Credit (CVC) battery cell requirement have moving forward? Will EV battery production be akin to the New Deal in the U.S.? What about the politics and challenges of producing battery cells, primarily with Asian partners? How will regional regulations impact the powertrain and battery strategies of automakers?

“Season two of EV InSIDER Live got off to a great start in April with a timely examination of EV fast chargers,” said O’Leary. “Loren and I are now looking forward to welcoming a battery expert like Mr. Gross and, together, exploring the exciting challenges and opportunities that lie ahead.”
