Dr. Ron Lasky, Senior Technology at Indium Corporation, explains how simple tweaks to day-to-day operations can drastically improve electronics assembly uptime and productivity in an interview with SMT expert Phil Zarrow.
Indium Corporation has developed a range of flux-cored wire solutions to meet the needs of virtually every electronic assembly and rework operation from no-clean flux-cored wire for circuit board assembly to activated flux-cored wire for non-sensitive electronics and electrical applications.
No-clean fluxes include:
Core 230-RC is low-spattering, halogen-containing for high reliability assemblies
CW-807 halogen free for high reliability assemblies
CW-807M, which has a small addition of halogen activator for more difficult to solder assemblies
CW-807H for high temperature alloys
CW-802 is recommended only when no halogen is a must and the process is well-controlled
Liquid rework fluxes are packaged in convenient pen dispensers, providing the optimal fluxing with no waste. Flux pens utilize a spring-loaded applicator tip to deliver a controlled amount of flux to the work surface. The user friendly pin-point application is deal for touch-up and light assembly work. Liquid fluxes include:
FP-300, a water-soluble flux that is compatible with both SnPb and Pb-free assemblies
FP-500, a halogen-free flux that is compatible with both SnPb and Pb-free assemblies
NC-771, a halogen-free, low-residue, all-purpose flux that passes the SIR test in the un-reflowed state
TACFluxes® have a variety of uses including rework and repair of various electronics assemblies and components, SMT component attach (including BGAs and flip-chips), BGA ball attach, preform soldering, and virtually any application where flux is required. Indium Corporation manufactures a complete line of TACFlux®, which include no-clean, water-wash, and RMA-based fluxes.
