GOB packaging technology is essentially SMD technology, but it reinforces and strengthens the SMD screen. A layer of special transparent epoxy resin is evenly applied to the surface of the assembled SMD module. After curing, this adhesive forms a high-hardness, high-transmittance protective layer that encapsulates all the LEDs, solder joints, and leads, creating a protective
