Webinar: Use of residue free pastes in vacuum soldering equipment

Residue-free pastes provide tackiness and printability, and do not leave residues behind after reflow. The advantage is a noticeable cost saving, as there is no need to clean the substrates after soldering.

Residue-free pastes do not contain any activators. Therefore, formic acid must be used to deoxidize the solder powder and the interconnect surfaces for successful soldering. Residue-free pastes also release significantly more volatiles than resin-based solder pastes, which require special handling of the volatiles in the oven, e.g., to avoid frequent maintenance.

Join this webinar at next week’s Virtual Conference, presented by PINK GmbH Thermosysteme, where we will discuss the properties of residue-free pastes and technical solutions for vacuum reflow equipment.
