I have found that preheating the solder pallets prior to use helps cut down on the solder balling. Also, we do not cool the pallets between passes and we use a spray fluxer because a hot pallet will knock down the head on a foam fluxer. We use WS f

I am using a Novastar 12S solder wave with Kester water soluable fux 22-2425. I have used this for years without problems on an old Hollis machine. Just started using the Novastar and after fine tuning I get itermitten bridging on the front of the P

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

I may be mistaken but I believe that the solvents have defoaming agents in them. I get less foam when I use the solvent than when I don't. If you dissolve the flux in water and agitate it I believe it will foam. I haven't had any over flow issues w

Hi, I need the RF 800 Flux Acid titration procedure and also require EPT of the same to add thinner ( RF 800 additive), i.e we are using the flux rf 800 for our wave soldering process having foam fluxer , after 2 hours we are taking sample from the

We too had a problem with the WS609. We have since switched to Alpha's WS619 (same formula with an anti-foaming agent) This really helped but we still monitor flux application and try to minimize wherever possible. Chris

We've got a Novastar 12S wave solder machine and we've been using Kester 951 flux for years with no problems. We just got a new bottle of 951 and it does not foam correctly (thin foam with lots of large bubbles). After a lot of back and forth with

| Could someone please help me. We clean our PCB's with Safewash at present. As most of our work has to be upto MIL-STD, we cannot clean the PCB when transformers are fitted? Could someone please help???? | Thank you | J Kirby J, You have a couple

| | Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there

We used an air knife using foam fluxer and no clean flux to remove excessive flux from the boards for a better look afterwards. A secondary effect might be that the flux is forced into the vias giving you better results on the top. If you feel a need
