It is cost-effective and also protects the PCB effectively. Even with many components and connections, this material is effective to apply. Liquid Photo Imageable (LPI) solder mask is an example of this epoxy liquid. It provides a solder mask with green, red, and blue colors.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">The liquid solder mask is applied to the PCB surface and cemented by curing.
