Simultaneous Lead and Lead-free Convection Soldering from Rehm Thermal Systems
Rehm Thermal Systems is delivering advanced thermal performance for manufacturers around the world with its Dual Lane Vision X Series convection soldering system. Enabling simultaneous lead-rich and lead-free reflow soldering in a single system, the technology is ideal for manufacturers looking to run parallel processes conveniently and cost-effectively.
The Dual Lane Vision X Series is equipped with two conveyor lanes which can be operated asynchronously at different speeds. Employing this unique multi-track variant, manufacturers can also operate the two lanes asymmetrically with different lane widths. The two conveyors can be loaded with diverse PCBs printed with different solder pastes, while a flexible heating system enables the selection of ideal reflow profiles for the separate products. Rehm’s Vision X ovens utilize homogenous, non-separated heating and cooling zones across the entire width of the conveyor, increasing operating convenience and reducing investment cost compared to other dual process design offerings.
Commenting on the technology, Rehm Export Sales Manager Martin Meyer explains: “Although RoHS is a fact of life in production facilities around the world, a few time-limited exceptions to the ban on lead force many manufacturers to work with tin-lead along with lead-free solders. Separate SMD production lines or continuous recipe changeover increase manufacturing costs and complexity. Here at Rehm, we’ve developed a convenient and cost-effective alternative with our unique Dual Lane Vision X Series – a reflow system that accommodates two parallel processes. Enabling highly flexible process setup and opening a wide soldering process window, the system is revolutionizing our customers’ thermal performance.”
Based on the innovative Vision Series convection reflow soldering equipment, the Dual Lane Vision X Series is a future-proofing system providing reliable, repeatable soldering results. Available with either an air or nitrogen atmosphere, the Vision Series offers an integrated residue management system including the company’s Rehm Pyrolysis technology in the heat zones. Virtually maintenance-free, Pyrolysis splits long molecular chains into shorter ones to reduce the amount of condensable waste and unwanted dripping within the process chamber. The result is efficient and environmentally friendly disposal of contamination and increased user productivity.
