Hi Indy, Check http://www.jmw-inc.com (they are in the midwest so shipping will not be too bad going out east). I bought 2 MPM printers and a pick and place machine from them late in 2004. I know they have 5-zone reflow and 7-zone ovens there (elect

This sounds like something the saleman of your new Vitronics oven should be happy to help you sort through. ECD [and probably other profiler supplers] provide software for playing with [optimizing?] recipes. In it, they allow you to select from a v

Hey all, I have 3 questions about reflow. Hopefully someone can help me. 1. I am having a problem. I set the peak at 230 and my mole thermocouples are telling me the temp in that zone gets to 237. How is this possible even if the thermocouple

We handle a similar SMTA quantity in house and use a 5 zone SMTmax AE-F530C 220V Single Phase Equipment Outline Size L-2000* W-612* H1220 mm Heat Zone Length 1000mm Equipment Weight 180kg Max power 7kW Belt Width 300 mm PCB Size 280x280 mm Comp

Hi there I have a question about reflow oven for Pb-free technology. I've noticed that some of the manufactures offer reflow ovens with short (26-30 lenght in cm) heat zones others offer longer more then 30 cm. So there are ovens with total heat len

hi all What do you think about soldering pb-free in reflow oven (air) lenght 1,7m (5 zones top,bottom) with max zone temp. 300C? Do you think that this process will be stable? Our max PCb dimension 260x260 mm. When i compare different oven producer t

Dave, For lead free, I've always left the ramp part the same and just spike higher in the reflow zone. I've also slowed things down a bit (5" per sec. slower)....without using prediction software, try, say... Z4 200 & Z5 260.

The second one is typical. The important temperature is the temperature of the joint, not the setting of the oven. The oven setting are only important because they determine the temperature of the joint. If you set the oven to 150, that will be th

The temprature for the first zone should be less as the PCB entering the oven from the ambient shop floor temprature would suffer a thermal shock from a higher temp. Experience must be gained from profiling a board with thermocouples, otherwise you

We have a 5 zone oven and were starting at 150 which brought it up too fast. Even with only a 5 zone starting at 140 we get the temp up to soaking temp fast enough. ( I think too fast actually) What kind of oven do you have anyways? And I can't
