I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe

Regarding the reference (Patrick) to a previous thread promoting �no-residue� fluxes, I must say that there is absolutely no such thing as �No-Residue� flux. There are �Low-Residue� fluxes and even �Very-Low� residue fluxes but to suggest that there

We use hot air leveling (HAL) process in pcb production. HAL process is 3 steps. �n 1. step flux. 2. step is HAL. And 3. step is rinsing. As you know there is mustn't any flux after rinsing operation. Our flux chemical is water soluable. But there ar

Rather than cleaning a water soluble flux residue off the board, by encapsulating the product. covering the board or the component with lets say a Hysol encasulant. Would this prevent the active flux residue from migrating and deteriorating the elect

I should have mentioned... the only flux we use for the hand soldering is wire-core, no bottle flux. I think it should be a non-issue to leave the activated wire core flux residue. I'm just looking for some way to prove it to the designer.

Hi, Walter, Why don't you try no-clean flux? We ever met the same condition, later, we changed to no-clean flux solved the problem.

Our PCBs manufactured with no clean flux have a waxy film on the board...is this normal? Our contract manufacturer recently switched to no clean from water wash. Thanks Carl

Hi Happy New Year HASL fluxes Are very conductive so best advise is get it all off. thanks greg

celsius or fahrenheit? I am not entirely familiar with the deeper details of HASL, but 130F-140F is adequate to clean many of the water-soluble fluxes used for component soldering.

Hi, We were having flux residue entrapment under the component. So we are evaluating to add steam cleaning with DI water, using precision micro prior to Di wash. Have anyone tried this and what are pros and cons. Your advice appreciated. Thanks
