Benefits of photonic soldering in a roll-to-roll format

Production form factor is a strong determinant of the product produced and cost per unit. Currently, majority of electronics are produced in a semi-batch sheet-to-sheet (S2S) process flow. In this mode, each board is fed through individual steps in sequence. However, in such a format, the size of the board is limited, the substrate would need to be dimensionally stable and the unit costs would be high. Consider the case of building an illuminated wall. In a S2S format, the illuminated wall will need to be in smaller pieces stitched together, the wall will be built on a rigid substrate, and has been cost prohibitive because of manufacturing and instillation costs.

What if the illuminated wall could be built like old fashion wall paper?

PulseForge® does more - like soldering on curved surfaces!

Aug 2, 2021 3:14:57 PM / by Harry Chou posted in Photonic Soldering


We’ve talked about the various ways photonic soldering simplifies the soldering process, like how the PulseForge can be thought of like a grill. Here, I’m sharing an example of how photonic soldering can help engineers overcome design limitations they face when creating new devices for the 3D world around us, while traditional electronics designs have been constrained to 2D (rigid) substrates. We can overcome these limitations using photonic soldering.

If you can grill, you can become a photonic soldering master!

Late fall in Austin is beautiful. Temperatures are in the mid-70s and it’s relatively dry – making it a great time to be outdoors. Combine the weather with Texans love for barbecuing and grilling, and eating outside with friends becomes a daily activity.

Photonic curing and soldering

Apr 13, 2020 9:20:33 PM / by Rudy Ghosh posted in Photonic Soldering, Photonic Curing


How Does the Photonic Curing Process Work?

Light energy incident on a body will be absorbed and heat up the object. The light-matter interaction determines what fraction of light is reflected back, transmitted through or absorbed by the body. The fraction of light absorbed can be guessed by the color of the body (darker material absorbs more light). Light that is absorbed by the body is mostly converted to heat and shows up as an increase in its temperature. That’s why wearing a black shirt in the middle of a Texas summer isn’t the most comfortable thing to do.

Photonic soldering in printed electronics

Current Material Options

If you have ever disassembled any electronic device, you know that inside you’ll find a variety of components, such as resistors, capacitors, chips and controllers that make everything work. All of these components usually sit on a rigid board (with copper tracks on it) that allows these parts to talk to one another. A major consideration in the choice of materials for building conventional electronics is the material’s ability to withstand high temperature (a required step in building electronic devices). But if those high thermal requirements could be relaxed, it would open up a wide variety of material options which, in turn, would allow new forms and functionalities – while reducing unit costs.
