2015-08-28-kester-news-bono1Recently, Kester submitted commercial products of NP505-HR, NF372-TB, and 985M to a third party laboratory for Bono testing. All these Kester products passed at a level that indicated no corrosion in the residues.

What is the Bono test?

SIR and ECM tests have been recognized by IPC as a way to evaluate paste or flux residue corrosiveness after reflow, the Bono test was developed and implemented in some French companies as an extra qualification criteria.
The Bono test also quantifies the corrosion, unlike current SIR or ECM tests. And in addition to characterizing solder paste residues, the Bono test can be performed for wave soldering fluxes, repair fluxes, and tacky fluxes using the same method and same board.
