Device removal can be done when the substrate is heated until it is certain that all solder
joints are molten. The chip can then be carefully removed from the substrate without
damaging the tracks and solder lands on the substrate. Removing the device must be
done using plastic tweezers, because metal tweezers can damage the silicon. The
surface of the substrate should be carefully cleaned and all solder and ux residues
and/or underll removed. When a new chip is placed on the substrate, use the ux
process instead of solder on the solder lands. Apply ux on the bumps at the chip side as
well as on the solder pads on the substrate. Place and align the new chip while viewing
with a microscope. To reow the solder, use the solder prole shown in application note
AN10365 “Surface mount reow soldering description”.
16.3.4 Cleaning
Cleaning can be done after reow soldering.
