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. This shift not only reconfigures PCB production logic but also signifies
The concept and importance of Board PCB Assembly In modern electronics manufacturing, board PCB assembly is a core link connecting design concepts and finished product functionality.

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
