With the rapid development of electronic products toward miniaturization, high performance, and high reliability, High-Density Interconnect (HDI) printed circuit boards have become a key enabling technology in advanced electronic packaging.
PCB dimensional change—often referred to as dimensional stability issues—is a long-standing and unavoidable challenge in printed circuit board manufacturing. It directly affects inner-layer registration, outer-layer alignment, impedance control, BGA assembly yield, and overall product reliability.
PCB Slot holes—also known as oblong, oval, or irregular holes—are widely used for connectors, positioning features, and mechanical retention in printed circuit boards.
In PCB fabrication, stack height (the number of panels drilled in a single hit) has a direct and quantifiable impact on hole quality, positional accuracy, tool life, and overall yield.
UL certification plays a vital role in ensuring the safety, reliability, and market acceptance of printed circuit boards (PCBs), particularly in North America and other regulated markets.
Hot Air Solder Leveling (HASL) is a widely used PCB surface finish, and it can be divided into leaded HASL and lead-free HASL.
PCB soldering quality is not determined by a single process step, but by the coordinated control of design, materials, equipment, and human operation throughout the entire manufacturing flow.
PCB stands for Printed Circuit Board, the abbreviated term for printed circuit boards. Typically, conductive patterns formed on insulating materials according to predetermined designs—either as printed circuits, printed components, or a combination of both—are referred to as printed circuits.
Surface Mount Technology (SMT) is a critical process technology for secondary integration. This technology primarily consists of key processes such as solder paste printing, component placement, reflow soldering, and cleaning.
Printed circuit boards (PCBs), born in the 1940s, have seen the development of numerous distinct types over more than seventy years since their commercialization in the 1950s.
