Kester RF550 Rework Flux is a high-reliability, zero-halogen, no-clean rework flux designed for electronic component rework and repair applications. RF550 has a gel-like consistency and is packaged in syringes for easy dispensing. RF550 can be precisely dispensed onto specific areas that require flux. After being dispensed, RF550 stays in place until soldering occurs. RF550 has excellent performance in applications requiring high reliability. RF550 is the ideal choice for QFP or BGA semi-auto- mated rework applications and is well suited for use with through-hole repair. RF550 compliments Kester’s high reliability line of products which are formulated to leave safe residues.
