Soldering defects: wet defects, bridges, horns (solder with flux)

We will introduce knowledge and techniques related to soldering defects, such as material selection.

Wet defects, bridging, and solder spikes are all issues caused by the active agents in the flux. During soldering, the active agents decompose and volatilize due to heat, leading to depletion. When depleted, defects such as wetting issues, bridging, and solder spikes occur, so it is possible to prevent these defects by continuously supplying fresh active agents to the soldering area. By supplying small amounts to the soldering area, fresh active agents are always present, achieving good wetting. This is particularly important in robotic soldering, where the final results can vary significantly. Additionally, reviewing issues such as excessively high soldering iron temperatures, insufficient heater capacity, and mismatched dimensions between components and the soldering tip is also effective. We offer flux-containing solder that demonstrates excellent wetting properties across a wide temperature range and for various mounted components. Please contact us through our website for samples. 【Overview】 ■ Review of soldering operations - Achieving good wetting by supplying small amounts - Reviewing issues such as excessively high soldering iron temperatures, insufficient heater capacity, and mismatched dimensions between components and the soldering tip is also effective - Using flux-containing solder with a wide temperature range and sustained activity to prevent defects.
