Need 100% solderability?
As the picture shows, these abrasion pencils are excellent to solve/rework any conductor solderability problems that are due to tarnishing from the environment, palladium oxidation from overglaze firing or to remove any stray overglaze deposited (by pinholes in the screen) over conductors that require soldering.
These abrasion pens are also often required to improve solderability of conductors, particularly palladium/silver, when printed on top of dielectric.
Part No. TFA043
