Modern electronics have gotten to be the spine of nearly each industry—transforming how we communicate, work, travel, and indeed mend. From smart phones and restorative devices to automotive frameworks and mechanical apparatus, the control and productivity of electronic items depend intensely on a significant but regularly neglected component: the printed circuit board (PCB). More particularly, it is the PCB assembly process—the craftsmanship and science of assembling components onto these boards—that breathes life into crude plans and changes them into high-functioning assembled circuit boar

Wearable technology has rapidly evolved from niche gadgets to mainstream essentials, encompassing everything from smart watches and fitness trackers to medical patches and augmented reality glasses. The core of these compact, sophisticated devices lies in their Printed Circuit Boards (PCBs). Unlike traditional electronics, wearable devices demand PCBs that are not only miniaturized but also flexible, durable, and capable of operating reliably in dynamic environments.

The unique requirements of wearable devices present significant challenges and opportunities for PCB assembly. Designers and

When discussing the development trend of printed circuit board (PCB) technology, we noticed is moving
towards high precision, high density, and high reliability. However, at the same time, the appearance
quality standards of PCBs are becoming more and more stringent. For example, the solder resist coating
is not only required to have a certain thickness and hardness, and pass the solvent resistance and
adhesion tests, but also must have a uniform surface color and gloss, and no impurities or excess
traces.

The appearance quality of solder resists reflects the technical level and manag
