HI-GRADE #7 BIO-CLEANER
Description
Hi-Grade #7 Bio-Cleaner is a biodegradable
aqueous type flux residue remover. It is formulated as a concentrate for dilution with
water. Hi-Grade #7 Bio-Cleaner very efficiently and effectively removes all rosin flux
residues and water soluble flux residues. Being alkaline in character it will, of course,
neutralize organic acid base fluxes.
Uses
Hi-Grade #7 Bio-Cleaner can be used in
spray-type automatic in-line cleaning and dishwashing machines. It can also be used in a
dip-type method. The cleaning bath concentration is to be maintained properly to get
optimum residue removal. When the pH falls below pH 9.0 additional bio-cleaner should be
added to bring the pH to 10.5 and to restore its cleaning ability. When the level of
cleanliness falls below the user’s standard because of saturation with residue and
contamination, it is important to remove the contaminated solution and recharge with fresh
mixture. Under normal conditions, frothing and foaming is minimum. If special
circumstances develop excess foaming, anti-foaming agents can be safely supplied.
Application
The cleaning power of Hi-Grade #7
Bio-Cleaner can be varied by varying the degree of concentration and the temperature.
Hi-Grade #7 Bio-Cleaner is normally diluted with deionized water to a concentration of 3
to 10 percent. However, the ratio of dilution can abe varied to suit each specific case.
Effective cleaning can be attained at room temperature, but optimum efficiency is achieved
at 140? to 160? F (60? – 71? C) with dwell time of one to three minutes. The dwell time
and bath life are dependent on the amount of flux residue load on the printed circuit
board.
After soluble reaction, rinsing two to five
minutes with hot water is recommended. A final rinse with deionized water is preferable
except where optimum cleanliness is not necessary. In any case, complete removal where of
bio-cleaner and flux residues are highly essential for product reliability.
Hi-Grade #7 Bio-Cleaner is completely
compatible chemically and physically with the residues, particularly all rosin and
water-soluble fluxes now in general use.

Safety
Hi Grade #7 Bio-cleaner, being alkaline in
nature, should be used in well-ventilated areas. Regular Safety precautions should be
followed to protect workers handling this material. If over-exposed, get medical attention
immediately.
