What is GOB?
GOB is a surface encapsulation process in which a transparent epoxy resin is precisely dispensed across the entire PCB surface, fully encasing the LED chips, bond wires, and solder joints in a single protective layer.
Two-part optical epoxy resin
≥ 92%
IP65 / IP67 / IP68
70–90 Shore A (adjustable)
−40°C to +80°C
1,000+ hours (QUV test)
PCB, FR4, aluminum substrate
0.3 mm – 1.5 mm (customizable)
Custom resin formulations are available for extreme temperature ranges, high-humidity marine environments, and rental-grade flexibility requirements.
Protection performance
Four failure modes eliminated by a single encapsulation step.
Processing workflow
Turnaround options include 72-hour standard, 48-hour express and 24-hour sample service with no MOQ and a monthly capacity of over 500,000 pieces; we accept customer-supplied modules, arrange return shipping and provide full batch tracking.
We receive your shipment, log each batch, and perform visual and electrical incoming QC to document the pre-processing condition of every module.
Ultrasonic cleaning, dehumidification bake (typically 60°C / 4 hr), and plasma surface treatment to maximize epoxy adhesion to the PCB surface.
Automated dispensing equipment applies the two-part epoxy to a controlled, uniform depth across the module surface — eliminating air pockets and uneven coverage.
Multi-stage UV + thermal cure cycle ensures full cross-linking of the epoxy matrix. Temperature and duration are profiled per resin formulation and PCB substrate type.
Optical inspection, drop test sampling, waterproof test verification, and full electrical aging test. Modules are packaged and returned with a batch quality report.
Why GOBfactory
Applications
GOB encapsulation is the preferred surface protection wherever LED displays face physical handling, weather exposure, or long-term outdoor operation.
