Ersa installs 2,000th VERSAFLOW 3/45
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.”
Modularer Aufbau,
flexible Erweiterung
Die große Akzeptanz der modular aufgebauten und erweiterbaren Ersa Selektivlötmaschinen weltweit geht auf ihre vielseitige Einsetzbarkeit zurück. Mischbestückungen mit THT-Komponenten und beidseitiger SMD-Bestückung lassen sich damit optimal fertigen. Anders als beim Wellenlöten ist dabei der Wärmeeintrag in die Baugruppe wesentlich kleiner und man benötigt keine Lötmasken. Die beim Wellenlöten eingesetzten Lötmasken schützen SMD-Bauteile auf der Unterseite der Leiterplatte vor dem Wiederaufschmelzen und Abspülen beim Kontakt mit der Lötwelle. Auch bei Kleinstserien werden diese benötigt und müssen jeweils einzeln angefertigt werden – dieser Zeit- und Kostenfaktor entfällt beim Selektivlöten.
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).
Powerful hardware,
first class service
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.“
