Effect tack soldering.
Flux
• Apply flux to the semicircular through holes on the four sides.
• Use a soldering iron having a large contact surface.
• Move the soldering iron in parallel with each surface
(with a feeling of causing the solder to flow).
• Pressing the semicircular through holes hard may cause them to get
crushed, so be careful.
• Make certain that no solder bridges are present.
