We have 2 different wave machines. An Electrovert with a foam flux and a Vitronics with a spray flux that is no-clean. We started noticing on the Vitronics that we were flooding inside the wave fixture. After further review we noticed that the angle

Dear Bruce, We had the same problem in the same condition. Every compnent and the PCB (OSP) has changed as lead-free and we need to solder them with SnPb. For solution we have increased the flux amount applied on PCB and the pre heat zone temper

I would use a foam fluxer since spraying rosin will make the stickiest nastiest mess you can imagine. 18 layer board huh? You will want convection preheat, both top and bottom preheaters, preheat tunnel of at least 4-5', a chip wave, laminar flow w

Ok so for me, spray fluxing is the way to go every time....for one you don't need to worry about colapsing your foam with pallet's that are hot or worrying about your pummace, your thinners, SG and so forth...man life in foam fluxer land was hard. N

Casimir, I have seen exactly what you are experiencing with the Kester 958 on other wave lines. No clean fluxes vary in how much flux residue is visually left behind. These no clean residues are typically not harmful to the PCB, but they are often

Hi All, We have been running a Novastar spartan 8S wave solder machine for a number of years. We actually do very little wave soldering and this machine has served us well. I have always been of the opinion that with the small pot and simple fluxe

It sound you have already discovered to root cause, flux entrapment in the via holes. Short of changing the desing, here are sone suggestions. The main thing is you have to dry out the via holes of the wet flux. Some things to try are: slow down t

I think it is better to forget foam fluxer in this case

Nope. I prefer foam.

I relate to your problem. We face this issue sometimes. It's mostly flux from SMT, TH process or rework boards. To avoid foam in our Washer, we soak the boards in hot water for 10-15 min before running it through the washer. Or you can spray the boar
