Why Choose Laser Soldering?

Laser soldering delivers superior connections, safeguards sensitive electronics,
and boosts productivity—making it the preferred choice for modern electronics
manufacturing.

Accelerated Soldering Speeds

Precise Heat Control

Fragile Component Compatible

Laser Soldering Process

1

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.

2

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.

3

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.

4

Cool-Down

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.

Advantages of Laser Soldering

Contact Soldering

Contact Soldering

Possible Stress

  • Physical contact to the substrate
  • Flux residue (carbide)

Dead Space

  • It is necessary to secure space for the tip and solder wire feed.

Solder Amount

  • There is a certain amount of solder that is brought to the wet surface of the tip.

Frequently Asked Questions

What are the most common reasons to select laser soldering technologies?

Micro Soldering (0.02mm spot), non-contact (allows for reflow only), no iron tip consumables, automatic spot size change.

Is laser soldering faster than contact soldering?

Laser soldering can be slightly faster because it eliminates some mechanical movement or when used only to reflow.

Does Japan Unix maintain FDA safety approval to sell laser machines in the US?

Absolutely.

How are the laser positions programmed?

Japan Unix was the first company to develop laser soldering more than a decade ago with the patented direct line-of-sight teaching camera that allows you to look directly through the laser beam. This makes teaching easy and avoid inaccuratie due to angle distortion.

Does Japan Unix offer pyrometer modulated power controls (power cruse control)?

Yes, Japan Unix is the leader in direct temperature measured laser control.
