I am waiting packages for TSSOP breakout boards and photoresist for etching, the toner from my printer is not soluble to acetone and gave terrible results, so did the thermal transfer method, and no CNC or laser engraver around, redrawing the traces with a sharpie was not accurate enough, and I love complaining as you see.
This looks bad, but it works!
1. Sand a blank single-side PCB: full of copper, not etched.
2. With a cutter, cut a rectangle of the exact size of the TSSOP minus the pins, so that the pins are not connected to the ground on the middle of the chip.
3. Solder the TSSOP chip to it. It will be very easy.
4. Remove as much extra solder as you can from around the chip with a soldering iron by dragging it away.
5. Sand each side of the TSSOP to remove the extra tin
6. With a cutter, cut lines on each side of the TSSOP to split the copper between each pin, and have tracks.
7. With a cutter, keep these lines going but widen then until you arrive to 0.1" (2.54mm) pitch (convenient for breadboards) until the edge of the PCB.
8. Drill holes between these 0.1" lines, put pins through, solder them.
You end-up with the worst-looking dev board possible to make.
Please, forgive my madness.
