Reduce flux

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?

Suppliers list the contents of their products in a MSDS. Libraries of these sheets are listed online. Look up the product you're using there. A safety data sheet, material safety data sheet, or product safety data sheet is a document that lists info

When usingnoclean flux or clean flux process?

Electronics Forum | Tue Sep 21 09:28:47 EDT 1999 | Jeanjean

Dear All, In order to understand the soldering technologies in SMT, I'd like to understand why some cards are soldered and then cleaned, or only soldered whitout water cleaning nor "ultra sound" wavelength. I mean that I wonder why we use toxic flu

Yer not making this easy. What kind of flux? If no-clean flux, what controls are you using to assure you are: * Applying the correct amount of flux? * Properly activating the flux? If water washable flux, talk to us about your cleaning methods and

Rework using flux pens

Your research is on track. NC flux needs to reach activation temperature. Also, do not depend on the corrosion characteristics associated with the flux classification (ie, L1, L0, M1, M0, etc.), until the flux is activated by exposure to soldering

Spray flux nozzle level

I'm now have target to flux saving. Could you please tell me. If we adjust level of spray fluxer nozzle up then we can saving cost of flux Quantity usage? What Others must adjust? such as pressure , flux flow. Thank you All for advise.

flux residue after HAL

The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

no-clean flux vs. impedance

Electronics Forum | Mon Feb 18 17:36:32 EST 2008 | kennyg

I should have mentioned... the only flux we use for the hand soldering is wire-core, no bottle flux. I think it should be a non-issue to leave the activated wire core flux residue. I'm just looking for some way to prove it to the designer.

Re: VOC free flux

David, Your concern is legitimate regarding the aggressiveness of VOC free flux. Water (the main substance of VOC free flux)is much more aggressive than alcohol. You will have an increased need to be more cautious from a compatibility standpoint, r

Problem with flux

Hello Armando, this is what I found into the handbook "Failure Analysis of Electronic processes" : "...Flux residues with water-soluble flux activators that are conductive and corrosive if left on in large enough quantities are detrimental. If you
