Enhancing PCB Reliability: A Guide to Via Plugging with Solder Mask Understanding Via Plugging with Solder Mask 1.1 Via Plugging with Solder Mask: Definition    Via Plugging with Solder Mask refers to filling or sealing via holes on a PCB using solder mask material, rather than leaving them open. The goal is to prevent solder from flowing into or through the via during assembly, which can cause so...

Via Filling in PCB Manufacturing: The Complete Guide to Materials, Methods, and Quality Control 1. Understanding Via Filling in PCB Manufacturing 1.1 Via Filling in PCB Manufacturing: Definition and Basic Concept    Via filling refers to the process of depositing conductive or non-conductive material into a via—typically a drilled hole used to form electrical or thermal connections between PCB lay...

Plugged Vias: A Key Process for Reliable and High-Density PCB Manufacturing Understanding Plugged Vias: Definition and Design Fundamentals 1.1 Definition of Plugged Vias    Plugged Vias refer to vias on a PCB that are intentionally filled with a specialized material such as epoxy resin or copper paste. This filling seals the via barrel and prevents solder or flux infiltration during assembly. Depe...

Understanding the Aesthetics and Engineering Behind the Blue Circuit Board     The Blue Circuit Board is not merely a product of visual preference—it is a combination of chemistry, light physics, and material science. At its core, a blue PCB is identical in electrical structure to other boards: it consists of copper traces laminated between dielectric layers, all protected by a solder mask. Howeve...
