Superior solderability testing fluxes are RoHS compliant.
Superior No. 99-25.15 meets the requirements of J-STD-002 Flux #1 for tin/lead solderability testing (Sn63/Pb37 and Sn60/Pb40).
Superior No. 99-25.39 meets the requirements of J-STD-002 Flux #2 for lead-free solderability testing (Sn96.5/Ag3.0/Cu0.5, SAC305).
These fluxes are made under strict conditions to ensure conformance with IPC J-STD-002 requirements.
Superior No. 99-25.15 conforms to Flux #1 and Superior No. 99-25.39 conforms to Flux #2 per the J-STD-002 as dictated in the standards as follows (note: the following is a direct quote from the J-STD-002 for the purposes of identifying the Superior Flux products that appear on this page as the correct fluxes for this specification):
“3.2.2 Flux The flux for tin/lead solderability tests shall be a standard activated rosin flux #1 having a composition of 25% ± 0.5% by weight of colophony and 0.15% ± 0.01% by weight diethylammonium hydrochloride (CAS 660-68-4), in 74.85% ± 0.5% by weight of isopropyl alcohol.
The flux for lead-free solderability tests shall be a standard activated rosin flux #2 having a composition of 25% ± 0.5% by weight of colophony and 0.39% ± 0.01% by weight diethylammonium hydrochloride (CAS 660-68-4), in 74.61% ± 0.5% by weight of isopropyl alcohol.”
If you’re looking for the rosin testing flux that complies with ASTM B678-86 then ask us about our No. 97-25 rosin flux. We supply our rosin solderability tests worldwide and are happy to answer any inquiries about these fluxes.
In addition to offering rosin solderability testing fluxes, Superior Flux also offers a full line of Rosin Fluxes including Type R, Type RMA and Type R fluxes.
