    Hi everyone I have problems welding QFN components in a 10-zone reflux oven, we cannot make a welding fillet that covers the entire QFN pin. Currently we use paste T4 - 63Sn / 37Pb. I enclose the curve of the oven profile. Any help or support on this topic is appreciated by improving the oven profile or better understanding this process thanks.
