You can, and for small parts you probably won't see much difference between body temp. and lead temp. For QFPs or PLCCs there will be a much greater delta, though. I'd be more concerned with the small surface area you're making contact on (spherica

Reflow profiles are based on the product and materials you are soldering. You need profiling software and a data logger.

I wouldn't think so, A thermocouple can be attached to the lead that is being soldered. Russ

I have a supplier that utilizes a soft beam solder process for through hole components. We are experiencing bridging and cold joints on components with narrow pitch between pins. They are dragging the solder over these pins as well. I have asked f

Hello! All I am an almost smt biginner. I have a few questions My question is 1. what will be changed to use lead free solder paste in a smt production line? 2. what is the reflow profile for lead free solder paste? Don't just tell me to search th

Call Heller directly, and give them the oven, and relative thermal density of the board, as well as the solder paste that you're using. They'll be able to give you a baseline profile to start from (both RTS and RSS). Otherwise, use a thermocouple p

Dr. Lee, For Pb-free solders, will the reflow profile be similar to that of Sn/Pb, with an flux activation plateau before going to peak reflow, or will the profile be more linear in nature? Are there advantages/disadvantages to either profile for P

Hi I'm trying to plot a LSP profile to reduce void. But I do not have much info about LSP. Does anyone know what are the specific times and temperature of the LSP profile? And are there any ways to eliminate solder void other than changing profile
