Thx to everyone who replied. we will be running single sided thru hole and double sided smt, 186 rosin flux cause they tell me it can take the heat needed for 18 layer pwbs. some long leads. also they are ordering in pallets to deal with the irregu

Yes I have read that standard, but it doesn't tell me what I need to know. Both have the same activity level and halide rating (L0) The AIM technical guy told me RO is a natural gum rosin, while (RE) Resin has more processing or something (maybe so

Obviously, if your customer instructs you to use a certain flux type, using THAT flux type is probably a good idea. Responding to your question: Chloride is one of the more detrimental materials found on printed circuit assemblies. Chlorides can com

It does sound like your leads are to long, speeding it up will reduce volume on lead and most will wick up the joint but when slow excess solder is left as long leads will have little flux left to aid drainage when it leaves the wave, thus giving a s

Most metal stencils today are cleaned with a water based cleaning solution. 3 choices are most typical: (1) Water only for water-soluble paste (2) Water + Organic for rosin and no-clean (low residues. This affords lower temperatures and is easier t

OR: Stands for organic (organic acid based flux) with the absence of rosin and/or resin. If you want to know everything about the classification of fluxes get the J-STD-004 �Requirements for Soldering Fluxes� at following link: http://webvision.ipc

Resistivity Of Solvent Extract [ROSE] is a bulk ion contamination [BIC] test method. It should thought of as a process control tool used to assess ionic contaminants. Don't consider it an acceptable tool for establishing 'GO-NOGO' limits. The stan

Mike -- Thanks for the information. It is very helpful. Is there any information available that shows what flux most companies are using? What fluxes are most companies that are producing Space, MIL-Spec, or other high-reliability assemblies usin

As you know there will be a lot of residues(such as rosin) left especialy on the peak zone and cooling zone of reflow oven after reflow soldering in a time. who use one kind of effective liquor or effective method to clean the residues ?
