When excessive voids occur in SMT soldering, simultaneously investigate the solder paste metal content, flux volatilization curve, and actual temperature deviations in each reflow oven zone. Focus on verifying whether the preheat ramp exceeds 2°C/s, whether the peak temperature is below 235°C or above 245°C, and whether the time above liquidus is less than 60 seconds or exceeds 90 seconds.

After solder paste is returned to room temperature, solder balls and spattering are likely to occur. The main causes are uneven volatilization of flux due to temperature difference, aggravated oxidation of metal powder, and sudden viscosity change. Standardized operation requires strict control of temperature, standing, stirring, and management of the time limit after opening, to avoid repeated freezing and thawing and excessive exposure time.
