According to Howard, we clean the flux tank on our wave solder machines every week. We replace it because flux sops up moisture from the air and contaminating materials from boards that are being fluxed prior to soldering. How would a prudent perso

Is there anyone who knows what the influence is of the dip-fluxing process on the placement accuracy of a flip-chip. If you perform dip-fluxing after component alignment, the component may be displaced on the nozzle; if you perform component alignmen

Consider: * 007 is a no-clean flux. Some no-cleans you can clean, some you can�t. You may be able to use a saponifier & surficant to clean the residue. Check with your flux supplier for recommendations. * 320�C is higher than the 315�C peak for th

Deltawave flux pump continously runs while in run mode. After the pump there is a flux manifold distribution block. When switching between fluxes not all previous flux is purged or drained. When no clean is installed some cross contamination may occu

George We're not sure about the application of powder flux for original poster to this thread, but a common application of powder flux is in brazing. This powder flux can be either metal bearing or just flux. As an aside: Soldering and brazing are

Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

We are doing a lot of CSP-BGA rework with tacky flux from Senju Metal.Their flux is very good.We are buying directly from Japan 529D flux. We have reworked BGA processor plastic sockets of Fujitsu Laptops. What kind of flux you are using? Not all of

Hello, we are currently running no clean flux on our Jade model pillarhouse selective solder machine and i would like to switch the flux over to Water Soluable. Are there any concerens with running water soluable on these machines? I have heard tha

Apply the bare minumum amount of VOC free typically 50% less than alcohol fluxes. By doing this you can keep the same top board temperature as alcohol, its only when people over flux do you need to boost up the preheater to volatise of the water. NEV

Assuming: * Customer board has been designed to provide for cleaning under components. * Cleaning equipment is capable. In meeting J-STD-001, your current cleaning equipment should be able to clean: * Water washable fluxes. * Low residue fluxes, pro
