Hi Dave, We suspect that the organic FM causes the non-wetting problem. FTIR analysis confirm that the FM is a flux residue. Dave we only used FTIR to detect organic contaminants, we also used SEM/EDX to determined the elemental composition of the

Dear Sean Contrary to believe MOST formulators of No Clean fluxes or No Residue fluxes use organic acides that are in fact weak and benign. IF the residue was left on the board and you had a condensing atmosphere then you may see some issue with fal

Coilcraft has posted the following and I am wondering how you folks are handling the use of coils in a Water Soluble world. PCB Washing and Coilcraft Parts Coilcraft tests for resistance to solvents per the following specification: Resistance to s

Eric, I assume you are talking about "VOC" as in (MXL-350VC "VOC FREE" Swing Spray Fluxer) since I have never heard of "VCO" used when talking about Spray Fluxers', or anything else for that matter. This is copied right from the SMTnet Library: VOC.

Donnie In response to your questions; 1. Flux is Multi-core X32-10M 2. Preheaters temperatures can range based on board density. the goal is to get the top side to 100C before wave. 3. Components can't be placed after wave solder, they are surface m

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

As I know, the encapsulation effect occurs only with rosin based fluxes. So if you have a PBA soldered using RA Flux, you should either wash it well, or leave it alone and it will be safe. For NC process the story is different because there�s no re

Have you examined what type of residue is present? It is possible that what you are seeing is benign, though flux that is not fully activated often leaves harmful residue species such as chloride or weak organic acids. If you don't want to change p

Where to find detailed information on fluxes? No one seems to know the real difference between Rosin fluxes with colophan, Resin fluxes or synthetic Resin fluxes, No Clean, Low Residues, VOC-Free, Halide-Free, Water Washable with alcohol base, Resin-
