Hello, I am looking for input on the 7 zone convectional reflow oven on the temperature profiling. I having a problem with the flux/solder spattering on the Au cotact fingers. I have ran some experiment with the soak time and reflow time. Anyway,

Maybe its not splatter, in my experience a sloppy operator can get paste on contacts and just one sphere can rune them and can look like splatter.

Sudden flux boil will cause splatter. More thorough drying or a slower intial ramp to allow drying to occur before a boil or "splatter" temperature is reached may aid your problem.

As per Travis's reply it could be something other than the reflow process. Another good one is if the printed PCB's have been cleaned down due to print misregistration etc.. If not properly controlled paste residues can remain distributed about the p

Over all time will be dictated by your conveyor speed. Your conveyor speed will be dictated by your products time above liquidous. Time above liquidous is dictated by the manufacturers specification. Time and temp before reflow will have to be ach

I can only say it looks okay for what you need, you will want a dual wave system it can make things so much easier. One thing to check would be the wave nozzle sizes I can see that the conveyor will do up to 15" but thats not to say the nozzle is

A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Get yourself a KIK Oven and Wave Profiler. It will get you in the Ballpark before burning down the joint. Easy to use and talk to your paste supplier. Murray

As others have stated, there are a few other things in the aveage assembly shop that are much more scary that a reflow oven. For instance, we have a wonderful wave soldering machine and w've been doing that kind of stuff for tens of years, but every

Agreed, I just bought a Electrovert Vectra Elite and have been very pleased with it thus far. I got the dual pot option for lead free changeovers and that has worked great. I can change pots in under 5 minutes, not counting the time to warm up.
