Thanks! It is right that solder paste is somewhat responsible for misssing components in our case. I took a look at the board after placement and I found that component hit the paste, but no where on the board. I guesss dry solder paste (operater pri

I have a PC graphics card that has a damaged component and I have no clue what it is. The other two that look identical are black flat top with which looks like a mini copper coil in the middle and two leads on each side. They are the last componen
