The reflow weldable low Rho chip is a PPTC chip that can be assembled with a reflowable soldering technique, as opposed to the spot welding process required by many other components, to save board space and reduce production costs. The advantages of the reflow-weldable low Rho chip is that it uses standard SMD assembly processes which helps reduce installation costs. The design helps to optimize board space since it uses the same space as existing terminal weld blocks providing direct thermal coupling of the PPTC to the battery.
