Chemtronics Circuitworks CW8500 No-Clean Electronic Grade Rework Flux Designed for BGA and QFP repair. Perfect for use when reflowing the GPU duringXbox 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.May be used with leaded or lead-free solders.Stored in a controlled environment. 2 year shelf life.A few warnings and cautions:For industrial use onlyWe can not offer advice on a specific application. For use by experienced electronics techniciansUser assumes all risk for application.Any warrantees are limited to replacement or refund of product.Always wear safety glasses when working with soldering equipment and materialsAlways use adequate venilation when working with soldering equipment and materialsAvoid breathing flux fumes emitted during soldering.Flux fumes may cause pulmonary irritation or damage.This product may contain chemicals known to the state of California to cause cancer and/or other reproductive harm.特点：高粘度残留物无腐蚀性，所以无需焊接后去除优秀的一致性与稳定的粘度无铅-符合RoHS标准。可使用含铅或无铅焊料。存储在受控制的环境。 2年的保质期。
