Photonic Curing
Photonic Curing is the high-temperature thermal processing of a thin film using pulsed light from a flashlamp. When this transient processing is done on a low-temperature substrate such as plastic, paper or glass it is possible to attain a significantly higher temperature than the substrate can ordinarily withstand under an equilibrium heating source such as an oven.

PulseForge® Photonic Soldering
How It Works
| Solder paste is heated indirectly through a light-absorbing layer and components. | |
| High contrast ratio absorption between layers allows for selective heating. | |
| Pulses of high intensity light are used in place of a reflow oven to heat the solder to its liquidus temperature in milliseconds without damaging the underlying substrate. | |
| High energy doses can be applied without damaging conductive tracks by protecting them with light-reflecting layers. |
How It Is Better
| Multiple types of components requiring different levels of heat can be soldered simultaneously. | |||
| Processing is much faster than reflow soldering and is roll-to-roll compatible. | |||
| Enables the use of standard lead-free solder pastes on temperature sensitive substrates – not possible with any other processing method. | |||
Photonic Soldering Process
Utilizing PulseForge photonic soldering technology, we are able to solder LEDs, resistors and capacitors onto conductive ink traces in a matter of milliseconds.
These were soldered using traditional solder paste SAC 305.
