LED Solder Assembly

Our LED solder assembly materials are designed for manufacturers who need a reliable, high-quality product that minimizes voiding and maximizes diode output. 

As LEDs have become more and more popular, we’ve kept pace with products specifically created to solve the problems faced by manufacturers.

FCT Solder’s LED soldering materials are designed with high-speed productivity in mind, to allow manufacturers maximized throughput. With the ability to print at up to 150mm/sec, our no-clean, lead-free solder pastes have become the gold standard for LED applications.

Our no-clean, lead-free solder pastes are popular for LED applications because our no-clean fluxes eliminate the need to wash away flux residues. Clear, colorless flux residues help maintain the brightness and reflectivity of the LED. In addition, shorter reflow profiles and high-speed printing increase manufacturing throughput.

Benefits of our LED solder

Fast & Efficient

Our paste is printable up to 150mm/sec, maximizing LED throughput and efficiency.

Prevents Overheating

It keeps components cool with its low voiding properties, allowing heat to escape. 

Clear Residue

No Clean flux leaves a clear residue for bright and reflective LED arrays

Read on for more insight on how our solder pastes can unlock a more efficient process and longer-lasting LEDs.

Solution-Driven Solder Assembly Materials for LEDs

LED (light emitting diode) technology has effectively replaced incandescent lighting in many applications. From automotive to in-home lighting to consumer electronics, LEDs have surged in popularity because they are relatively inexpensive to manufacture and make sense for many applications.

Although LEDs are prized for being more durable and longer-lasting than traditional incandescent bulbs, one of the biggest challenges manufacturers face when working with LEDs is heat. Overheating is one of the most common reasons LEDs fail. When heat can’t escape via the thermal pad, it dramatically shortens their lifespan.

FCT takes a solution-driven approach to all of our products. For our LED solder materials, we asked: what if we could eliminate (or dramatically reduce) the chances of thermal voiding for our customers’ products?

Designed to Keep Components Cool for a Longer Life

LED Assembly ArraySolder-paste induced voiding can prevent heat from escaping and cause delicate components to overheat and dramatically shortening the life of the LED.

Our advanced flux formulations are the foundation for solder materials that are designed to lengthen the life of your LED products. By reducing the chances of voiding, our solder pastes help ensure that any heat produced can escape and components remain cool.

The bottom line: LEDs won’t overheat, which results in longer lasting products.

Print Quickly for Better Productivity

Our pastes are designed for high-speed printing. Use them to gain efficiency, increase your throughput, save time and money.
