APPLICATIONS of Flux X33
Recommended for consumer electronics and general electrical soldering
applications, particularly where high throughput is desirable.
This is a robust product. Its process window is greater than that of the
demand for high performance/reliability.
RECOMMENDED OPERATING CONDITIONS
The Printed Circuit Board: Flux X33 (Stannol X33-12i) is recommended for use on clean copper or tin-lead coated PCBs. It will solder satisfactorily over most surface preservatives. It is recommended that these are applied no longer than 3 months before soldering, since the period of protection is limited dependent on storage conditions. Stannol X33-12i has been formulated to work over a wide range of solder resists.
The solvent system in Stannol X33-12i has been designed for optimum wetting of surfaces but prolonged contact with polystyrene, PVC or polycarbonate is not recommended. Machine Preparation: When switching to X33-12i from any other flux, ensure all fingers, pallets and conveyors are thoroughly cleaned. Fluxing: Stannol X33-12i has been formulated for use in foam, spray or wave fluxers in the same way as ordinary fluxes on standard wave soldering machines.
