Hi All, Recently, I need to deal with a customer complaint that specify the PCBA white residue (flux residue from ecofree 303) may be the reason why the board intermittent. Anyone have such experience with this flux? Anyone can tell me is this flux

Hallo Joanne, I had employed by producer of Ecofrec 303. We make many tests of corrosion and conductive test in our company. All results of this tests was OK . Vast majority correspond mil standarts. When I ask my labor assistent in BRY, white residu

Hi Radek, Thanks for your reply. I use this flux with manual soldering process for the product. Is this flux suitable for manual soldering? or it is only for wave soldering? I have sent the board for analysis, and the report shown that the white res

joanne please pay attention, each heavy no-clean flux residues not completely heated due to hand soldering becomes a moisture absorbing conductive pathway, causing electrical leakage. So I suggest you to clean well the board after hand soldering or

Hi Joane, this flux is primarily designed for wave soldering. I think that manual soldering it´s possible. Certainly it´s very hard to dispensing correct amount of the flux. Succinic acid is one from all ingredients of this flux. If you have this

Hi, I have noticed we are getting residue on our wave pcb's and it's worse with lead free, since we changed to the flux we are using. We are currently using Avantec VOC Free flux model Ecofree 303. It looks like it's made in Malaysia. Does anyone h

Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar

OK, if the sphere of the ball and the paste on the pad are both eutectic, 63/37 then the paste will reflow first causing a drop of the component, after which the spheres will reflow causing a double drop and a good intermettalic. You can see this by

For what you have right now I would recommend that you use soldering iron tips that are made for component removal. until you get BGAs I wouldn't worry a whole lot about the expensive rework equipment. I would use specialty tips and a heat gun wit
