Cobar selective soldering flux 94-SEL

A high-reliability, low-VOC selective flux, 94-SEL contains a small percentage of DI-water to reduce spreading of the flux during the selective soldering process. Featuring optimum soldering performance and reliability, the flux is specially designed to eliminate solderballing and  has numerous  automotive approvals.
