Lötfehler und Lötatmosphäre

Konvektionslötsysteme von Rehm Thermal Systems tragen durch optionale Stickstoffatmosphäre zur Vermeidung von Lötfehlern bei

(PresseBox) (Blaubeuren-Seissen, )
Die typische Frage an einen Hersteller von Reflowlötanlagen wie Rehm Thermal Systems lautet oft: „Was bringt eine Stickstoffatmosphäre?“ Dieser Frage gehen wir hier für die typischen Fehlerbilder nach: Es geht um Lotperlen, Beading, Voiding, Whisker, Graping, Head-in-Pillow, Benetzungsstörungen und Tombstone. Denn durch die gewählte Lötatmosphäre können unterschiedliche Lötfehler entstehen oder beschleunigt werden, jedoch auch verhindert oder vermindert werden. Die Konvektionslötsysteme der Vision-Serie von Rehm Thermal Systems sind als Luft- oder Stickstoffanlagen konzipiert.
