  • Apply a small bead of flux onto each solder pad.

  • If you're using solder paste, apply a small amount of paste instead. Most solder pastes contain flux.

  • Use tweezers and picks to carefully maneuver your component so that it straddles between the solder pads.

  • This can be very tricky depending on the size of your component! Take your time and don't press against the component too hard, or you may fling it out of place.

  • Double-check the component orientation if it's electrically directional (such as LEDs and diodes). These components normally have a bar indicating the cathode (-) end.

在每个焊盘上涂抹一小滴助焊剂。

如果你使用焊膏，则只需涂抹少量焊膏即可。大多数焊膏都含有助焊剂。

使用镊子和撬片小心地移动您的组件，使其跨在焊盘之间。

根据组件的大小，这可能非常棘手！慢慢来，不要用力按压组件，否则可能会将其甩出原位。

如果元件具有电气方向性（例如 LED 和二极管），请仔细检查元件方向。这些元件通常有一个指示阴极 (-) 端的条。
