Does anyone know where the power to the lambda, chip sensors comes from on a Electrovert EPK plus? I have an intermediate issue with these sensors loosing power and the wave just keeps going higher and flows over the pot. I have replaced the senors

Call 1-800-737-8110 for tech support. They can give you the N2 supply specs for the 650C. You should consider the cost to convert the Contour to a standard Lambda vs. the cost to bring in N2 and the consumable costs. Tech Support can give you the ret

Morning Mike, We use Pb63/Sn37, Alpha Metal alloy. Solder pot is at 250 C. The profile of board after Preheat about 100 C, Lambda Wave about 220C (use both Lambda and Chip wave), DWell time 2.1s ~ 3s. Conveyor speed 1.5 in/min. We run by bare board a

I just got back from a visit to our PCBA manufacturer. We have good flowthrough on the PTH, but solder skips and bridges on the SMT SO IC's. We have correct orientation and robber pads, but the results are still the same. I noticed the wave shape is

SMTneters, I'm famialiar with lambda, omega, and gemini waves but not with "A" wave. Can somebody give me an explanation? thanks Tom B.

We are running an RMA flux (Kester 1515). Changing the angle didn't help any so we're back at 6 degrees and placing an order for the lambda nozzle changeover. Are you currently running the debridging knife?

Guys , Thanks for all your inputs on this one. I have had to increase preheats dramatically aswell as increasing conatct time over lambda wave. Joints are perfect. Cheers,

What type of preheaters do you have on you're wave? I have to agree with Dave. Your leads are not cold, they are hotter than the annular ring on the PCB. This would cause the solder to go to the lead only rather than the component and land pad / a

I have the identical machine and setup as you with the same issue(s). I looked at setting up for N2 but am choosing to retrofit to a standard lambda nozzle setup. If you are soldering bottom side SMT parts or other challenging assemblies, N2 may ma

Hello!I have a delta wave with these problems:offtime of lambda wave tracking is too long and when modify offtime setting to a negative value for a fast stop on tracking position of lambda wave, the wave pass on stand-by with a delay of half of leg
