Cobar 95-DRX+ is a new low-VOC flux that offers the best of both worlds. This flux is based on a water/solvent combination and offers improved soldering performance as well as wicking characteristics that approach a solvent-based system, resulting in perfect hole filling.
Cobar 396-DRX+, a new VOC-free flux, is RoHS-compliant and fulfills the need for more environmentally-friendly materials, maintaining excellent soldering performance. It is halide and halogen-free and is based on a water carrying system that provides advantages in transportation and storage conditions and eliminates fire risks. Operators also will appreciate that this flux provides an odorless flux solution.
According to IPC-J-STD-004, the Cobar 396-DRX+ and Cobar 95-DRX+ are classified as ORL0. These thermally stable Cobar fluxes offer a wide process window with topside preheat temperatures up to 150°C. Due to the strong thermal resistance, these fluxes can be used in a broad range of applications, such as high thermal mass and heavy multi-layer products that require extended and higher soldering conditions. The Cobar 396-DRX+ and 95-DRX+ activation systems eliminate bridging and provide excellent through-hole filling for lead-free as well as leaded applications.
In addition to these fluxes, new stronger versions called Cobar 396-DRX-M+ and Cobar 95-DRX-M+ also are available. These fluxes are classified ORM-0 and provide excellent soldering performance in the toughest applications, leaving no visible residues.
Cobar Solder Products is the U.S. division of the Balver Zinn/Cobar Group.
