I have inherited a SonoFlux 9500 spray fluxer. It appears to have never been used and was build in 1999. It is missing the nozzle and a couple of other parts. Would it be worth it to get this thing up and running to replace a foam fluxer? Does an

Need some feedback here. We're running a foam fluxer using WS chemistry (AIM 715M). We have been running almost exclusively .062 and a few .093" PCBs but we've recently started running some boards that are .100 and .125 thickness and are having tro

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

Look at your fluxer as well (spray or foam?). You may not be getting ample flux over certain areas of the board. This can cause voids.

Tell us more ... Have you checked the density of your flux? How old is the flux? Is this a spray or a foam fluxer? What type of maintenance is being done? Do you get good hole fill with the the tank pressure of 130 on other boards?

I haven't seen a hydrometer used in years. Are you still foam fluxing? There used to be automatic units available, but with the advent of the spray fluxer, they may have dried up. If you are still foam fluxing with alcohol thinner, place ping pong

We made the same change a year ago, from foam to spray fluxer. One of the reasons we changed, to keep the acid number within specs (foam fluxing) we had to measure once or twice a day and add DI water to make up for evaporation, all along not able to

| | 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
