The latex should not influence your closed-loop filtration - unless of course it falls off during cleaning. The issue would be with water soluble materials. As Dave (hi Dave) said, the clay based version of these will clog/blind/knacker your carbon

Wolfgang: Boy it's tough to convey context in this medium, isn't it? Clipped from our paste storage work instruction, environmental effects on paste are: 1a Avoid excessive heat (over 80� F). It causes flux separation, reducing print quality. 1b

We've run for about 2 years with SN100C on a Stainless pot, and all looking OK at the moment - we have just drained the pot and swapped to a similar solder (customer request)so we had a good look as we were interested to see what was happening. To be

The backflow in the wave started to become very important with the development of no-clean/no residue fluxes. These fluxes don’t have (or at least shouldn’t have) rosin, resin or other vehicles in the formulation which encapsulate surface oxides from

I have some CERSOT-23 transistor packages with castellated terminals. The 4th lead (drain castellation) is electrically connected to the top of the device by the castellation. The castellation goes up the ceramic body and contacts the metal package

| Does someone has experience with solder stop on components to avoid an Viking effect (no solder on the pad, all solder on the lead)? What kind of solder stop does work well? What is dangerous? What has to be kept in mind when using such components?

I'm just shooting ideas here, but maybe a via hole in the middle of the solder pad would drain the excess solder by capillary force? Or using a tin plated PCB and printing flux only, then place and reflow. depending on the thickness of the tin plati

Based on what you have said so far it would be worth trying extra pads and as you may know the drainage pads should be a minimum of three times the length of the pads before them to be effective. Also take some parts stick them to a glass plate and r

jng123, Process-wise using one solder paste type is preferred regardless of paste type. If you want clean both paste types in one cleaning machine your manufacturer might have, this potentially could lead to white residue issue due to chemical reac

Yes, I've used the muffin tins. I drained a solder drag pot. Steve makes a good point about the drain valve. When I drain my pot, I will be scooping out the solder and filling my tins.
