Try spraying flux on top of the loaded PWB when you put it on the conveyor. The tackiness of the flux does a pretty fair job of keeping the axial leaded parts down to the board. This takes more cleaning, but it has worked wonders for me on assemblies

I read my posting again, and it didn't sound right....what I meant was slow down your conveyor speed BY .5 to 1 FPM. So, if you're running @ 4 FPM, slow it down to 3.0 to 3.5 FPM.

I was running the conveyor at 3.75 when we started the discussion with Electrovert. Unfortunately, foam fluxing is a fact of life for us. Our products have open contact relays that can become contaminated by spray fluxing. Titration is our only me

My company just purchased a Vecta (E-vert) wave soldering machine. Bridging has become a serious issue, both on SMT components and thru hole. We are currently seeing about 500 ppm. The products that are being run now were run previously on our old

We are using NR300F from Alpha. Topside board temp is 220 deg. F. We have 3 bottom side convection preheaters, and we use a foaming fluxer. The machine (except for the rotary chip wave) is almost identical to the old econopak. An electrovert appl

I sent you a couple of charts to assist with your troubleshooting. One is the Electrovert Wave Solder Troubleshooting chart and the other is Sandia Labs/Electrovert Optimum Solder Contact Time. Electrovert has a 6 deg. conveyor angle standard on the

John - CK can probably help you further once you answer those questions, but for now what's your top side temp and how are you applying flux? Two of the primary causes for bridging are conveyor instability (vibration) and turbulance in the solder wa

I'd have to disagree with the Electrovert applications guy. I'd recommend SLOWING down the conveyor between .5 to 1 FPM - effectively, you're REDUCING contact length (because contact length = dwell time * conveyor speed), hence getting better peel-o

We got a F04 error (internal Memory fault) on the shared drive and entered 8 in location N001 as per the maint manual and cycled the power. I then set all the locations listed in the manual to thier default settings. Now the motors do not run to thei

Well, im not sure what plane you guys are on, but I can back up my what im talking about. Ya see I wnet to Soltec traingin back in 1995 for our new wave. I got a diploma proofing that I know what i'm talking about. no one else in my company has on
