Grant, Newer lead-free fluxes have 6%-10% solids content - more activator, therefore leave more "visible" residues. Old technology tin-lead fluxes got down to as low as around the 4%-6% range (I'm going off memory, so me might be wrong)... You'll

I have recently started to use RMA flux (customer requirement) for some of our projects. I am finding that some of my BGAs are slightly off. Not enough to be rejected but enough to cause concern. In the past I have been able to rely on the surface te

Indium Corp. has some, 3549-HF and 3590-T, both are OK for foaming. Most of the better performing newer fluxes require spray application for best performance. Alpha, Kester and others have wave fluxes too. http://www.indium.com/products/circuitboar

it's a vacuum dewar so adhesives will eventually permeate and the vacuum would be lost. Sounds to me since I have the N2 capability, I definately should try it. I am obtaining Indium Flux and Solvent so I can adjust the activity when I start using

OK guys, we got our Adipic acid. What is the preferred methode of applying it? a) Nozzle mounted, momentarily turn off wave and then brush? Or b)coat nozzle with the acid then mount it and turn wave on? By the way, we are using Indium flux WF-994

Senju for WS and Indium for NC. Flux is 2235 Kester !

Mario, I tried a couple of profiles. In all cases the preheat ramps fairly slow, while the reflow utilizes the radiative heater to speed to reflow as quick as possible. I tried a quick profile and a slower one. The quick has about 15-20 sec at pre

Does anyone have any recomendations for a NC flip chip attach flux? I have info from Indium and Kester. Who else makes a good flux for flip chip. I will be dispensing this flux using a doctor blade and rotating disk. I will then dip the flip chip

PR, are you using the Indium or the Alpha Flux, I couldn't tell by your response. Russ
