Hi, I am using a 7 zone Conceptronics oven and Indium 3.1 lead free clean paste. Our profile is as follows, 130 140 150 180 200 240 260 with a belt speed of 36 inches per minute. I dont know if that will help you out though...

We have recently acquired a Passaat SMRO-0406 oven. The manual is uninformative for oven settings. Can someone supply us with starting points for conveyor speed, Zone 1 to 4 and 5 to 8 temperature settings please? Our boards for a product we manufac

starting point with zone settings would be, 100 / 160 / 200 / 225 / 260 deg C...but you'll have to check the exact profile on the pcb with a reflow profiler....making sure you meet the paste spec and making sure you don't heat any devices up to quic

We are not having any real issues. I am just first setting up a lead free profile, and was looking for a starting place. So far it's going well. Can you tell me more about why your paste would be better and I'll pass that on to the decision makers?

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.

Hi, We have a 5 zone oven and we use a RTS Profile. Our last zone is the zone that the reflow takes place. some basic analysis is as follows: TAL 70 secs, peak temp 210,ramp rate seems fine. A typical setting is : Z1 140 Z2 160 Z3 160 Z4 185 Z5 220

soldering a very simple board in a very simple Accuheat oven. Can anyone give me basic starting point settings (conveyor speed and temperature) then we will profile using a mole from there. Paste 1) Tin Lead Paste 2) Chipquik low temp TL 165C PR

Hi Small ovens work fine if the settings are correct and I seriously doubt 55cm/min is right. Profile it and speed down to around 35cm/min. Increase first zone to around 170 keep second at 208 but increase last to around 280 BUT profile to check it

You must thermally profile your circuit boards with a data-logger and thermocouples. Just putting in oven set points and looking at solder joints is not enough. Reference IPC-7530

Get in touch with your paste manufacturer. They should have a data base of different oven types/zones, and can give you "baseline" settings for a medium thermal density board that has been proven to work well with their paste. After that, it sounds
