While you're waiting, consider giving your paste manufacturer a call. They should have a database of recommended, or starting point profiles based on what oven you have. cheers, ..rob

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

Hello We use a 5 zone conceptronics HVN70 and never before have we had something we could not do including 6 layers Rohs complicated boards. Recently we had a larger - simple 2 layer board - all 1206's etc however there are 15 pcs of a LARGE high m

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

First things first. Check the manufactures specs on the electrolytic caps as they may not be able to handle the lead free temps.

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

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

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?

There is a procedure for profiling on my web site that may be of use to start with www.bobwillis.co.uk | We are about to run our first BGA devices and would appreciate some confirmation on a few points. | First some details: | PCB & Device: | ======

So the first two zones come on and the last two come on, and the middle zones start dropping temperature? What happens if you let that go?
