Nitrogen for selective and wave soldering at SIEB & MEYER AG
Two nitrogen generators supply N2 for selective and wave soldering systems for electronics production
SIEB & MEYER AG was founded in 1962 and is an internationally successful company in the field of industrial electronics. An IMT PN 1550 and an IMT PNC 9200 nitrogen generator from Inmatec produce the nitrogen required in the factory for selective and wave soldering processes for the manufacture of the electronics.
The company's 220 employees develop and manufacture control technology and drive electronics. In addition to controls for mechanical engineering, automation technology, servo amplifiers for a wide variety of drives, frequency converters for high-speed motors and generators are also among the company's core technologies.
For many years, several Inmatec nitrogen generators have been used in production, including an IMT PN 1550. The generator produces 2.1 m3 of nitrogen with a purity of 99.998% per hour. This is used as part of selective soldering with ERSA soldering systems. Here, the nitrogen is used to protect the soldered connections from oxidation during the THT assembly of printed circuit boards.
An IMT PNC 9200 nitrogen generator supplies an additional 40 m3 of nitrogen with a purity of 99.99% per hour. 21 m3 of the inert gas is used to manufacture THT components in a SEHO tunnel wafe system. The remaining 19 m3 are used to manufacture SMD components in a reflow soldering system. With these processes, N2 also helps to prevent contact with oxygen during the soldering process and to ensure the high quality of the solder joints. A buffer tank stores a large amount of N2 to enable flooding of the tunnel wave with up to 21m3 N2 within a few seconds.
According to the production management at SIEB & MEYER AG, there has not been a single failure of the system since the first generator was installed 15 years ago. In addition, they are very satisfied with the quick response time of the Inmatec sales and service partner Druckluft Evers GmbH - Ahrensburg, who takes over the maintenance work for nitrogen and compressed air generation on site.
