Hi Peter, which should be the best cooling rate once belove TAL by using L-F alloy ie. SAC 305 ? Tnks GS

Contact your paste supplier and see what they say. My information on SAC 305 FROM MY SUPPLIER was - "The cool down rate is not as critical for Pb-free solder joints, as it was for SnPb. The grain sizes do not differ is size in the Pb-free bulk solde

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

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

dear experts, i want your suggestion for getting a profile in Heller 1707 mk iii series re-flow machine ,its 7 zone machine recently we had a solder ability issues , so pls guide me ,how to set rts profile parameters

Back-stepping a bit. If a profile is being used to: * Set-up the oven for a new product or trouble-shooting process, the profile should be taken with a solid contact to a solder connection. * Monitoring on-going stable and in-control process that re

when taking a reflow profile, can i attach the thermalcouple to the component body (using high temp tape) instead of to the leads (often found thermal couple dettached during reflow). in general, what is the temp diff between these 2 locatinos. if so

I like to secure the thermalcouples with a small dot of chip-bonder(surface mount adhesive). The chip-bonder will cure durring the first pass through the oven. After I have developed my profile I remove thermalcouples and the chip-bonder with a solde
