Hello,
I have a PIC10LF322 in a DFN8 package and a DRV8838 from TI in a WSON package, both with 8 pins. I milled a PCB and I am trying to solder these devices to the board. I have tried feeding solder to it, hoping it would go under the package, this didn't work. I have also tried cutting a stencil out of 50 micrometer thick metal. I could place solder paste onto the pads, but when I heated it with a hot air gun, the solder didn't grab the leads.
A friend suggested it is hard to do this by hand without solder mask. Has anyone had any success? I found numerous videos and resources, but they tended to use PCBs with solder mask. Should I try a thicker stencil and have another go with the milled PCB? or cut my losses and send the PCB out to be made? If I missed a previous thread on this, let me know.

Extend the pads out from the package almost as if it had leads. This gives you a place to apply your iron and solder. Tin the pads, just a flat thin layer, use plenty of flux and use the extended pad to apply the solder.
