Okay I was not thinking of the Suzuki, So I would not have any input there. Zones to me does not include the cooling, I also do not count the top and bottom individually as zones. So to me an 8 zone oven would have 16 heaters that you could set, 8

Last year I bought in a 10 zone reflow to replace our 6 zone. This was due to a number of reasons but mainly the 6 zone oven was not long enough to cope with solder voids on Ceramic bases using LF paste. Without knowing your product, just ensure tha

This has always been a big debate on what is better. Few things to consider before getting into number of zones. What is the throughput and cooling requirements? Throughput is a direct relation to length of heating zone. Longer heating length

Reason I ask is because I've never really paid much attention to the cooling rate, but I'm currently running a 10 zone oven and using all 10 zones for heating whereas I've almost always used a 10 zone as 9 heating and the last as a cooling. I'm curr

how many layer board is it? what kinda temperatures is your oven currently hitting. In our reflow oven I have been using a profile that is the same for the top and bottom at zone 1 111C zone 2 at 164C zone 3 at 161C zone 4 at 208C and zone 5 at 2

More zones = higher thruput. Is it better to have (8) 12 inch zones vs. (7) 15 inch zones? One thought might be more parts = more cost = more potential for failure. I have a bunch of BTU's with over 12,000 heating hours of combined opertion. I

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

I am seeing a problem of flux droping on the PCBA during reflow. This is a pb free process and I am using KOKI pb free paste with 8 zone (and some 9 zone) reflow ovens. Line throughput is about 10,000 boards/24 hours. I suspect that the exhaust is no

We are currently experiencing with our SMD Solder Reflow Equipment on Shooting-Up Zones (Zones 3,4,5,7 & even Cooling Zone). PV exceeds about 5-10 degrees with the SP. (ex: SP=140deg, actual PV = 145deg & higher). Our equipment undergo a monthly prev
