Hot presses primarily melt solder through heating and pressurization to form an electromechanical connection. Heating methods include pulse heating (rapid heating through voltage and current adjustments) and electromagnetic heating (precise temperature control using temperature sensors).
Common types include:
1. Constant Temperature Hot Press: Maintains a constant temperature, suitable for continuous production environments.
2. Pulse Hot Press: Uses pulsed current heating for rapid temperature rise.
3. Vacuum Hot Press: Operates in a vacuum environment to prevent oxidation.
