VPS Condenso Vacuum condensation reflow system is said to minimize void rates by subjecting the molten solder to a vacuum, removing residues and gas inclusions that would otherwise result in voids in the solidified joint. Reportedly can produce solder joints with surface contact ratios of greater than 99%. Releases even heat during condensation and maintains constant temperature. Limits maximum soldering temperatures so PCBs do not sustain damage from overheat.

TS7000 Interchangeable Material Path Series Rotary valve is based on the technology of TS5000 Series Rotary Microvalve. Is designed with no dead fluid volume, field replaceable feed screw/cartridge assembly; is interchangeable with TS5000DMP feed screw auger inserts, has a flexible motor, syringe, and a needle mounting option. Is available in three feed screw auger sizes (16-pitch, 8-pitch and high output 8-pitch), all made of hardened steel. Encoder motor version is available for applications that require closed-loop motor control with encoder feedback. Reportedly provides repeatable dispensing of medium- to high-viscosity fluids and pastes. Applications include small-dot dispensing of dispensable-grade solder pastes, silver epoxies, surface mount adhesives, dispensing beads of structural adhesives, cavity and cam filling, and glob top dispensing.
