Hello I am making a drone with sp racing f3 flight controller but while soldering i removed two diodes by mistake C13 or C12 something was written like this and i lost them what can now i do can i make connection directly
Thank You

Link to datasheet / product page? Picture? C12 C13 sound like capacitors, not diodes.

Sounds like a dustbin visit to me .

C12 and C13 are, as noted above, capacitors not diodes (diode reference identifiers normally start with D, capacitors start with C)

If you have access to the schematics, you can determine the values of those parts, and with dial calipers you could measure the size of the pads to determine what package they were in, allowing you to order replacements. No clean gel flux might be helpful in soldering them and preventing a solder bridge under the cap.

However, since they are almost certainly tiny SMD parts, and your soldering skills and equipment are such that you accidentally removed them while doing other soldering on the board (I assume of connectors or headers?), I am not optimistic about the chances of success in this endeavor.

i have never done smd soldering and I also dont know where could I get those parts and yes they are capacitors so connecting them is essential and this is the link of the product https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwju6ePpkuXgAhWTjY8KHacsAZEYABATGgJzYg&ohost=www.google.com&cid=CAESEeD223bI1eprCx8FdEwGYxm2&sig=AOD64_0mGSsqM_2XomEzZ8j3oMUA-ypfsA&ctype=5&q=&ved=0ahUKEwjI9NzpkuXgAhXVdn0KHaNrC_sQww8IOw&adurl=
