In high-density PCBA manufacturing, the conformal coating process faces a unique and critical challenge: shadowing. Components, connectors, and dense layouts often block UV light, leaving hidden areas on the board that are completely unprotected and vulnerable to moisture, dust, and electrical shorts. This compromises product reliability and can lead to costly field failures.

You shouldn’t have to choose between fast production and complete protection. You need a solution that reaches where the light can’t.

Engineered for Total Coverage

Incure Ultra-Illumina™ 3511 is a specialized UV curable conformal coating with a secondary heat-cure process, meticulously engineered to solve this exact problem. It is the professional’s choice for ensuring complete, uncompromising protection on even the most complex board geometries.

The Dual-Cure Advantage

The core of Ultra-Illumina™ 3511’s value is its dual-cure process. The UV curable aspect provides an instant, fast cure on all exposed areas for rapid production throughput. Meanwhile, the secondary heat-cure process reliably cures the “shadowed” areas under components and in tight spaces, ensuring every part of the board is fully protected. This eliminates the risk of uncured spots and provides a foolproof layer of defence.

Superior Flexibility and Unwavering Quality

Beyond its dual-cure capability, Ultra-Illumina™ 3511 is a highly resilient coating. With a remarkable 400% elongation, it provides superior flexibility and durability, ensuring the bond remains intact through thermal cycling and mechanical stress. Its fluorescing feature allows for easy in-line inspection, giving you complete confidence in every board that leaves your facility.
