Kester® 285 RMA Flux Cored Solder Wire
A mildly activated rosin flux-cored solder wire, classified as Type ROL0 under IPC J-STD-004, designed for high-reliability SMT and electronic soldering applications.
Product Overview
Kester® 285 RMA Flux Cored Solder Wire combines high-purity rosin with a synergistic blend of activating agents to deliver superior wetting and solderability. Originally classified as Type RMA per QQ-S-571, this flux demonstrates stronger activity than standard mildly activated rosin fluxes and achieves performance comparable to fully activated formulations.
Engineered for the electronics industry, Kester 285 is ideal for Surface Mount Technology (SMT) assembly processes that require dependable soldering performance with low residue. It is particularly suited for demanding manufacturing environments where a mildly activated rosin flux ensures reliable, repeatable results without the need for extensive post-solder cleaning.
