How does salt spray affect LED screens in the Philippines?

Salt spray accelerates the oxidation of solder joints and PCB components, leading to dead pixels and short circuits. It is particularly dangerous in coastal cities like Cebu and Davao.

What are the advantages of GOB technology for coastal businesses?

GOB (Glue-on-Board) provides an airtight seal that prevents salt mist and moisture from reaching the electronics, effectively stopping corrosion and extending the screen's life by up to 50%.

How GOB Technology Prevents Salt Spray Corrosion for Coastal LED Displays in the Philippines

Published: 2026-06-15

For business owners in coastal cities like Cebu, Davao, and even Metro Manila, maintaining outdoor LED displays is a constant battle against the elements. While the tropical sun is intense, the hidden enemy is often the salt spray carried by ocean breezes.

If your LED wall isn't protected, salt spray can lead to rapid corrosion, short circuits, and a total loss of investment. This is why GOB (Glue-on-Board) technology has become an essential requirement for coastal installations in the Philippines.

Why Salt Spray is Deadly for LED Screens

In a coastal environment, the air contains high concentrations of chloride ions. When this saline mist settles on a traditional SMD (Surface Mounted Device) LED screen, it initiates a chemical reaction:

Oxidation of Solder Joints: Salt acts as an electrolyte, accelerating the oxidation of the copper and silver solder joints that hold the LED chips in place.
Component Corrosion: The delicate circuitry on the PCB (Printed Circuit Board) can corrode, leading to flickering, dead pixels, and eventually, the failure of entire modules.
Moisture Absorption: Salt is hygroscopic, meaning it attracts and holds moisture. This keeps the internal components damp even during dry hours.

The GOB Solution: An Airtight Shield

GOB (Glue-on-Board) technology provides a physical and chemical barrier that traditional screens lack. By applying a high-transparency, optical-grade epoxy over the entire module surface, GOB creates an airtight seal.

Salt Mist Barrier: The epoxy layer is completely impermeable to salt ions.
Corrosion Resistance: Because the electronic components are never exposed to air or moisture, oxidation is virtually eliminated.
Impact Protection: Beyond salt, the GOB layer protects against physical impacts and fine dust particles.
