Time Domain Reflectometry: PCB Defect Detection

During PCB layout, designers typically have to indicate the impedance of traces to ensure a proper balance of low-loss characteristics and power-handling capabilities. Before layout, the designer determines the trace width in some field solver software based on the desired impedance and other stackup factors like the surrounding substrates‘ dielectric constant(s) and the distance between…

Solder Mask Expansion Ensures Solder Joint Reliability

Even small-lot PCB manufacturing relies on automated solder deposition processes to expedite the assembly process while providing greater consistency in solder application/joint reliability. Solder masking is necessary to prevent unintentional bridging of exposed copper and enhance the reliability of copper features that do not require atmospheric exposure. Using a carefully cut stencil, manufacturers apply an…

Fine-Pitch PCB Assemblies for HDI Design

High-density pinout components using a package-on-package (PoP) construction, most notably ball grid arrays (BGAs), feature pitch (pin-to-pin distances) much smaller than historical standards. Given their proliferation in modern electronics due to their broad functionality, designers and manufacturers have had to adapt processes to accommodate the tighter pitches. Fine-pitch PCB design focuses on how layout and…

HASL PCB Surface Finish Process

PCB manufacturing is divisible into two primary stages: fabrication and assembly. The surface finish process inextricably links them together, ensuring sufficient bonding between the bare board and the components for continuous performance and extended reliability. PCB surface finishes come in many flavors, but HASL is the most prominent for non-consumer devices: as an extension of…
