Boards that pass AOI can fail in the field weeks later—often not because of the soldering profile, but because of how they were handled and stored. Invisible ESD damage, moisture, and contamination can partially damage components that pass every test, only to fail in the field. This guide walks production leaders through the complete decision path for protecting boards from receiving dock through line-side delivery.

Wave soldering processes up to 1,000 boards per hour at 260°C—but exposes everything underneath to extreme heat. Selective soldering targets only specific joints, protecting sensitive BGAs and cutting defect rates to under 1 percent. In 2026, the right choice isn’t about finding the best method—it’s about matching the right process to your board complexity, production volume, and quality requirements.
