Basic UL Knowledge for PCBs
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.
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.
Copper clad laminates (CCLs) are the foundational materials of printed circuit boards, providing both mechanical support and electrical functionality.
In the era of deep integration between mobile internet and smart devices, smartphones have become the core equipment for daily life and work for users worldwide.
Wave soldering is a device that welds electronic components onto printed circuit boards (primarily involving flux application, preheating, soldering, and cooling).
Printed circuit boards (PCBs) serve as critical components connecting numerous electronic components. Routing is the core aspect of PCB design, requiring the fulfillment of multiple constraints while achieving circuit functionality.
PCB step slots, also known as controlled-depth slots or non-through slots, are recessed grooves milled into specific layers within a PCB board without penetrating the entire board. Imagine them as “pits” dug between the “floors” of the PCB.
PCB, also known as a Printed Circuit Board, enables electrical connections between electronic components and facilitates functional implementation. It is a crucial component in power circuit design.
With the rapid advancement of electronic power technology, DC/DC power modules are widely adopted in high-end equipment across aerospace, power electronics, 5G communications, and military electronics.
