Cobar 390-RX-HT Flux无卤助焊剂

　　1. deion product

　　cobar 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 high- tech and industrial applications.

　　390-rx-ht is resin based and is classified according ipc-j-std-004as relo.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.

　　2. 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 4c

　　do not:exceed storage temperatures above 30℃.

　　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.

　　3. handling

　　the recommended ambient conditions for applying the flux are18-25c.

　　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 ofoil 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.
