Dr. Lee, For Pb-free solders, will the reflow profile be similar to that of Sn/Pb, with an flux activation plateau before going to peak reflow, or will the profile be more linear in nature? Are there advantages/disadvantages to either profile for P

Look to: * Your flux supplier's recommendations to baseline your recipe [similar to using your paste supplier's recommendations for setting your reflow recipe] * 7530 'Guidelines for Temperature Profiling for Mass Soldering (Reflow and Wave)' for gui

Dear all, I would like to learn from all regarding purpose of each profile stages, such as preheat, soak, peak cooling. At what stages, flux start to be activated? Thanks for your time,

Change pastes, although insufficient heating may leave excessive residues. Is this on one board or all products? No Clean or water soluble? Do you profile accurately or "guesstimate" your settings?

Almit are specialists in formulating fluxes for pastes and wires for the very very demanding Japanese assembly market. And the key to good SMT is how the flux performs...and our formulation improvements are driven by requests from the companies who a

From Indium Guru, (Hi Rich). "Ramp can be taken anywhere.... but mainly you want to look at the ramp when the flux is doing it's job. For the Indium paste, I would set a ramp rate of 100 to 200 (or 120 to 210).. somewhwere in that range should provi

| Hello all, | | Our guys here still have some questions on the "optimized" profile which sees a more moderate ramp up straight to reflow temperatures versus the conventional profile which has a plateau at around 150 Celsius. If the optimized profi

This person needs to have the "mental faculties" and a basic understanding of science, and understand concepts like flux, solder paste, time vs. temperature curves, etc. Do they have to be a metallurgist?? Of course not, but at the minimum they hav
