Frequently Asked Questions
Why choose MacDermid Alpha liquid fluxes?
Options are available for virtually any electronics or industrial soldering application. With our global network, we ensure seamless, copy-exact product availability, optimizing supply chains and reducing costs for multinational operations.
Are all liquid fluxes safe for electronic applications?
No, only a select number of fluxes, known for their high electrochemical reliability, are specifically designed for circuit board assembly. Many others are intended for industrial soldering applications.
Can all fluxes be used in both wave and selective soldering applications?
No, due to shorter process times, selective soldering applications require different fluxes than those used in wave soldering.
Do all liquid fluxes work in a lead-free soldering process?
No, only certain fluxes can withstand the higher temperatures required in a lead-free soldering process.
