Is this a white residue on the joint and surrounding area's, if so the only thing I can remove it with after cleaning is an Isopar(Isoparrafinic hydrocarbon), my guess looking at other pastes where I have seen this is it is a type of wax used in form

| | 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

Steve What do you mean by better? More/less activity? fewer retouches? longer shelf life at ambient temperature? less hygroscopicity? longer open time on the stencil? easier to wash? easier to treat waste water? easier for washing machine maintenanc

It is true that the use of saponifiers (and other water soluble additives) will lower the surface tension and aid in under component penetration. It is also true, however, that other specific design features within a batch machine can also aid in un

| | | I require some feed back from any one who knows about using a voc free flux in a nitrogen wave solder machine soldering both through hle and smt componants. | | | What disadvantages are there when using this flux? | | | Do you have any contact

Haaaaa!!!! Soldering to plastic!!!! An apt analogy!!! I like to compare it to soldering to dirt. Some thing. In fact, you are soldering on nickel, when soldering on many things. It�s just that the gold, er Pd, flash enables the wetting mechanism

There are several manufacturers of batch-format de-fluxing systems. Here is a list of them: Aqueous Technologies http://www.aqueoustech.com (909) 944-7771 Batch and Inline UnitDesign http://www.unitdesign.com (714) 672-9944 Batch Austin American T

1) why is No-clean (NC) the preferred process, for BGA mounting by SMT? Probably the same reason NC is the preferred process for mounting non-area array SMT components. 2) why is water-soluble (WS) not a hot choice? There�s not reason not to use
