Esqueci um resistor no meu protótipo de PCB – como faço para adicionar um?

If your PCB has a solder mask, you can fix this with an SMT resistor even when traces are close together. Cut the trace and scrape the solder mask away on both sides of the cut, over a few mm. Solder an 0603 ou 0402 over the cut. If I patch like that, I actually make two cuts a mm apart, and remove the trace by dental pick between both cuts to make sure there’s a decent interruption of the trace.
alternativamente, you can do the same and solder a PTH resistor, whose wires you first bent so that they lay flat on the trace. Won’t probably work as well on narrow traces, like 0.5mm.
