Cleaning
To determine whether the following solvents, often used to remove flux residues and other sub-
stances, are suitable for the capacitors described, refer to the table below:
Type
Ethanol,
isopropanol,
n-propanol
n-propanol-water
mixtures,
water with surface
tension-reducing
tensides (neutral)
Unsuitable
Suitable
Solvent from
table A (see
next page)
Solvent from
table B (see
next page)
MKT
(uncoated)
MKT, MKP, MFP
(coated/boxed)
Suitable
In part suitable Unsuitable
Suitable
Even when suitable solvents are used, a reversible change of the electrical characteristics may
occur in uncoated capacitors immediately after they are washed. Thus it is always recommended
to dry the components (e.g. 4 h at 70
°C)
before they are subjected to subsequent electrical test-
ing.
