Laser Soldering Process
Pre-Heat: In both processes, the temperature is gradually raised to prevent thermal shock to sensitive components. Flux is applied to clean the surfaces and promote better bonding.
Heating: For contact soldering, a heated iron tip is used to transfer heat to the joint, melting the solder. In laser soldering, a focused laser beam is activated to rapidly heat the solder and components, ensuring precise control over the temperature to avoid damage.
Post-Heat: Solder is applied to the joint in both methods. In contact soldering, the molten solder fills gaps and forms a solid connection. In laser soldering, the solder melts and flows into place, creating a strong bond without overheating surrounding areas.
Cooling: The iron tip or laser is removed, and the joint is allowed to cool, solidifying the solder and ensuring a reliable electrical and mechanical connection.
Both techniques ensure a secure solder joint but differ in their heat application—contact soldering uses a heated iron, while laser soldering uses a focused beam of light.

Both techniques ensure a secure solder joint but differ in their heat application—contact soldering uses a heated iron, while laser soldering uses a focused beam of light.
Pre-Heat: Before soldering, it's important to gradually warm up the components to prevent thermal shock. With a laser, the beam warms the joint in a controlled manner, ensuring the temperature rises evenly without stressing the components. Flux is still needed to help with bonding.
Heating: This is where the real action happens. In laser soldering, a precise laser beam heats the soldering area without touching it, reducing heat spread to nearby parts.
Post-Heat: Once the joint is hot enough, the solder melts and flows into place. With a laser, the solder paste or wire melts instantly under the beam, flowing into the joint without overheating the surrounding area.
Cooling: After the solder is applied, it needs to cool and solidify. In laser soldering, once the beam turns off, the joint cools quickly, forming a precise and reliable bond.
