Oven for lead free...???

I would look at Vitronics-Soltec such as the XPM 820 or even the 520. BTU also makes very nice ovens. The Hellers I used to use went through blowers every 6 mos. and both of them came it defective. You must have got lucky or I got unlucky.

In 1995 we bought 4 Vitronics U520 reflow ovens with top heat only. We ran these ovens until 2003 for both curing and lead reflow with no problems. In 1998 we bought 1 U520 top and bottom heat and one U820 top and bottom heat and once again we had no problems with these ovens.

One day in 2000 the salesman for BTU came knocking at the door and told us about lead free and needing to obtain a delta T of 5 degrees centigrade. He showed us all the options that came with his oven and at the time the configuration we wanted was $15K more than the Vitronics.

We did the sums and looked at the specs and decided to buy a VIP98 with single forced cooling. We were amazed at how easy it was to create a profile which could achieve a delta T of 5 degrees centigrade across the board and through the heating zones. With our new found belief in BTU we purchased 5 more BTU ovens. These were the Paragon98's with twin forced cooling and all the options. We bought these two years old at Auction in 2002 and they were all less than 2 years old for $15,000 USD. These machines are even better than the VIP98's and would recommend them to anyone.

We had a few issues with the local BTU office regarding spares and support so we now go straight to the US for any technical help and I have to say they have not let us down yet. If I could buy the spares from them also I would not have to use my local office.

Hope this helps

Wow, I'm surprised everyone jumped onto the "Type Of Oven" bandwagon. Usually the type of lead free paste will determine your oven needs. Take these needs to most of the major oven makers and see if they can exceed these needs. Then take these oven makers and determine which would fit your compay best; you know, there local, there service, warranty etc.

One of my customer had an oven made of galvanized metal. when he rised the temperature for lead free application the zinc from the alloy(blower turbine and housing,...) was melted and was removed .I offered to my customer an used oven tornado made by specnor,this machine does not use galvanized parts(all the blower,chambre,... are made of sst)and presente a perfect profiling. that is why I suugest you before buying any oven contact these guys and come for a test. You will be very surprised for the price and the quality of the product hyabro

Question: If we run the same oven to run both lead free and lead paste. Will any lead contamination transfer to the lead free board by force conversion?
