390-RX-HT is an alcohol based flux for wave soldering applications under (partly) N2 atmosphere. This
flux offers highest ionic and optical cleanliness and provides outstanding soldering results for use in hightech
and industrial applications.
390-RX-HT is Resin based and is classified according IPC-J-STD-004 as REL0. The product is halide and
halogen free
See the Product Data Sheet (PDS) for the specification of the product concerned. Read the Safety Data
Sheet (SDS) before handling and/or using this product.
Receiving and storage
Store unopened cans in an explosion free storage preferable at a temperature below 20 °C or normal
ambient temperature. Fluxes are shelf-life items and should therefore be handled as FIFO supply
DO NOT: Expose to heat or frost
DO NOT: store the flux at temperatures below 4 °C
DO NOT: exceed storage temperatures above 30 °C.
Flux that has been exposed to frost should be placed in a room with central heating for at least 4 hours
and shaken before use.
Handling
The recommended ambient conditions for applying the flux are 18-25 oC.
Prior to using the flux, tank, spray nozzle, fingers, pallets/carriers and tubes should be cleaned properly. If
pneumatic air is used to apply the flux, the air must be dry, free of oil and temperature controlled. A water
and oil separator for the supplied air is strictly necessary.
It is important to start with components and board materials that meet requirements for solderability and
ionic cleanliness.
DO NOT: mix the flux with other fluxes
DO NOT: leave the flux can opened when remainder flux is still in the can.
DO NOT: utilize the flux in the fluxing system before flushing the tubing with IPA.
