| Product Characteristics |
Formulated for wave soldering of conventional and surface mount circuit board assemblies. Developed to minimize the formation of micro-solderballs during wave soldering. Designed for spray or foam applications. |
Formulated for wave soldering of conventional and surface mount circuit board assemblies. Developed to minimizethe formation of micro-solderballs between connector pins and CPU socket during wave soldering operation. Designed for spray application. |
Designed to improve effectiveness in wave soldering of conventional circuit board assemblies. Formulated to provide excellent cosmetic appearances yet minimizing micro-solderballing and bridging at connectors and CPU areas. The residue of 1868 is non-conductive, non-corrosive and tack-free that needs to be removed and posed no interference with electrical testing. Kester #1868 is also design for use of Lead Free Application. |
Most active VOC-Free Flux for optimal top-side wetting and solderballs reduction. May be applied by spray or dip process. Kester #979 is also designed for Lead-Free application. |
Developed to reduce bottom side micro-solderballing and survive SMT dual wave soldering systems. Maybe applied by spray or wave. |
