2.應(yīng)用

Spray fluxing is the preferred application to apply this flux. Make sure that the unit has a stable and uniform spray-cone.

The flux should have the finest droplets at the lowest possible setting for the atomizing air pressure. (Low air pressure give

bigger and unstable droplets; high air pressure cause bouncing effects of the flux against the PCB surface).

Use a scrap/bare board to set-up the spray parameters. Turn the board upside down after spraying for inspection. It is

essential that a continuous, uniform spray pattern has been deposited all across the board.
