Chemtronics Circuitworks CW8500 No-Clean Electronic Grade Rework Flux Designed for BGA and QFP repair. Perfect for use when reflowing the GPU during Xbox 360 "Ring Of Death" Repairs3.5 Gram (0.12oz) syringe - enough for 6-10 BGA repairsCW8500 is a high-viscosity No-Clean paste flux developed to assist in printed circuit board rework or repair. It is an effective paste flux for prototype work where a small amount of flux is needed on a specific area of a board or assembly. After being dispensed, rework flux stays in place until soldering occurs. Exhibits excellent performance in applications requiring a flux having good thermal stability such as surface mount component or repair.It is the ideal choice for QFP or BGA rework operations. It is also well suited for use with through-hole repair operations.Features:High Viscosity- stays where you put it.Residues are non-corrosive, so not need to be removed after solderingCompatible with most no-clean solders and fluxes.Excellent consistency with stable viscosityLead Free - RoHS compliant.
