Determine effectiveness of three cleaners
The purpose of this trial is to determine the effectiveness of three different cleaners for the removal of flux for Electrical Manufacturer.
Cleaning was performed for fifteen minutes at 160o F in a beaker aggitated with a stirbar. Rinsing was performed in a tap water bath followed by a DI water bath. Both rinses were for 5 minutes at 140 F. The parts were then dried under an air knife for two minutes and in a convection oven for 60 minutes (at 210 F).
After drying the parts were visually observed for any residual flux and/or watter spotting.
SUBSTRATE MATERIAL: Gold-Coated Aluminum
CONTAMINANTS: Rosin Solder Flux
CONTAMINATING PROCESS USED: recieved contaminated from Electrical Manufacturer
The black light showed that all the flux was removed from the part cleaned with the Calgon Geo-Guard 2215. There was a problem of water spotting on the parts. Both WR Grace cleaners were inneffective in removing the flux from the parts.
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
The Geo-Guard 2215 seems to be a suitable chemistry for Electrical Manufacturer's needs. The water spotting could be a big problem so a new rinsing and drying method needs to be determined.
