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

I am looking for the solder wire leaded or lead free which can withstand the solder joint at temperature 450deree Celsius or more after soldering, since i need to form a solder joint at higher temperature area Pls suggest the part number for the sam

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

Hello, Dr. Ning-Cheng Lee The melting point of solder PB-Free its to higher do you now the lower temperature of an PB-Free and its constitution. Its true if the solder paste have in its constitution a Bismut component the melting point its lower?

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

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
