Preventing the “Popcorn Effect” in Electronics & Semiconductors

The “Popcorn Effect” is highly regarded as one of the most frustrating phenomena in electronics manufacturing. It represents a hidden threat that can ruin the entire batches of printed circuit boards (PCBs).

In semiconductor and PCB manufacturing, plastic-encapsulated microchips and multi-layer boards are inherently hygroscopic—meaning they naturally absorb moisture from the surrounding air over time.

The Popcorn Effect is purely a humidity & temperature based failure caused when trapped moisture undergoes a rapid phase change inside a microchip during high-temperature process.

And each popcorn occupying roughly 1,600 times of the humidity present in the surface..

Since we cannot change the fact that microchips are made of moisture-absorbing (hygroscopic) plastics. But! We can surely control the amount of humidity the component is allowed to absorb during the process through seamless dehumidification because it is the only way to eliminate the humidity , the the sole cause  for the Popcorn Effect. 

The Climatronics way:

Our Industrial dehumidifiers control humidity in PCB manufacturing by manipulating a fundamental law of physics: vapor pressure differential(VPD). In PCB manufacturing, dehumidifiers maintains VPD, which is the hidden engine that dictates whether moisture aggressively forces its way into a microchip, or is safely drawn out of it.

To maintain the strict climate zones required to prevent defects like the Popcorn Effect, our industrial dehumidifiers physically strip water molecules out of it using specialized industrial dehumidification technologies.

Our dedicated team at Climatronics aware of the fact that the compound which encapsulates the microchips is highly hygroscopic. When exposed to humid indoor air, humidity slowly penetrate the porous plastic shell through microscopic diffusion. We mastered the art and science of sourcing the 

perfect Industrial dehumidifiers for all the PCB and semi conductor manufacturers and reduce the possibility of humidity related issues.

In a PCB and semi conductor manufacturing unit, industrial dehumidifiers reduce humidity by continuously manipulating temperature and Vapor Pressure Differential (VPD).

To maintain the exact micro-climates required across the factory floor, industrial systems rely on a distinct mechanical processes: Desiccant Industrial dehumidifiers for the main assembly floor.

Standard cooling systems cannot achieve the bone-dry environments required to protect moisture-sensitive microchips (MSDs). To stop the humidity and prevent the Popcorn Effect, factories deploy industrial desiccant dehumidifiers.
