Optoelectronic circuit boards integrate circuits and optical components into a single unit, yet manufacturing such PCBs using existing processes presents significant challenges. 3D (additive) printing technology offers a novel approach for producing these boards, enabling smaller, lighter, and more intricate designs compared to traditional PCB fabrication methods, whilst consuming less power and generating lower pollution.

3D printed pcb boards are spearheading a disruptive transformation in manufacturing processes. Unlike traditional fabrication methods—which commence with copper-clad laminates and progressively remove excess material through subtractive techniques such as chemical etching—3D printing employs an additive approach, building circuits layer by layer from scratch.

The layer of paint on the PCB surface is called solder resist ink, also known as PCB solder mask ink. Solder mask ink is the most common and primary ink used in PCB circuit boards. Typically, 90% of solder resist ink is green, though other colors exist, such as red, blue, black, white, and yellow,

In the production of HDI boards, solder mask bridges within BGA areas and between fine-pitch pads serve as crucial micro-isolation barriers despite their minute dimensions. Measuring merely 0.1–0.2mm in width, they must separate adjacent pads to prevent soldering short circuits. However, following selective OSP treatment, solder mask bridges frequently exhibit cracking, detachment, or erosion, leading

Smartphones predominantly utilise black PCB, not for electrical performance considerations, but as a strategic decision driven by aesthetic appeal, advanced manufacturing processes, and brand positioning. Given the highly compact internal structures of modern smartphones, the significance of PCB colour extends far beyond mere aesthetic enhancement. Whilst green PCBs remain predominant across broader electronics applications, smartphone
