Use the thermal recipe suggested by YOUR paste supplier, as the starting point.

As we have vitronics oven(SMR610A) made in dec,1997,which has 5 heating zones and 2 cooling zones. For Lead free soldering what should be our baseline for low/medium boards.we have gathered profiles from various paste manufacturers,however we don't k

Hello ! I have a vitronics 500s ( five zones), and the solder paste is ALPHA OM-338-PT lead free. have anyone a profile to start and test, i need some reference temperatures.and conveyor speed thanks !!!

try 180 180 195 248 260 belt speed 20 ( lightly populated boards) adjust speed to 18 for heavily populated.

Lead Free in 5 zones is tough sledding. Start with your manufacturers solder reflow profile and calculate your belt speed by looking at the recommended heating time for the solder paste vs. the length of your heated zones. Set your belt speed so tha

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

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

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

Doesn't the components and PCB need to be lead-free also to be a "true" lead-free process?
