WF-9942 is a highly active no-clean wave solder flux designed for use with through-hole and mixedtechnology assemblies. It has been effectively used in both tin-lead and lead-free soldering operations. WF-9942 is a second generation no-clean flux designed to meet the requirements of J-STD-004.
Although not specifically designed for lead-free soldering (third generation no-clean) or to the requirements of the later J-STD-004B (fourth generation no-clean), WF-9942 has been successfully and reliably used to assemble millions of circuit boards for the last 15 years. WF-9942 exhibits very good SIR and ECM results when tested to the J-STD-004 and Telcordia GR-78 requirements. A rosinfree fourth generation product comparable to the WF-9942 is Indium Corporation’s WF-9958.
