This article provided comprehensive insights into the various electrical and physical factors contributing towards impedance in PCB signal traces along with modeling/evaluation steps necessary for achieving precise control to meet signal integrity requirements up to multi-Gbps transfers. Careful stackup constr...
At its core, the objective of applying signal integrity practices in printed circuit board layout & routing is to guarantee that the signal remains uncompromised as it travels from its source to its destination. In simple terms, the objective is to guarantee that the signal obtained at the endin...
In a PCB, materials, the shape of the traces that create the circuit, the placement and thickness of various layers, and how current is transmitted between layers drive these effects. It’s also important to mention the closely related issues classified under power integrity. While signal ...
Trace Width Measurement is pivotal in PCB evaluation, directly impacting signal integrity and power distribution. Precision in measuring trace widths is essential to align with design specifications, ensuring optimal performance. Incorporating Trace Width Metrology techniques and devices guarantees stringent adh...
Copper Clad Laminate (CCL) is the base material of PCB. Bonding a layer of copper foil to a non-conductive substrate, such as fiberglass, plastic, or paper-phenolic made this laminate. The copper layer serves as the conductor for the electrical signals in the PCB, while the substrate provid...
inspection x-ray systems are capable of detecting numerous defects in pcbs that may be challenging to identify through optical or electrical tests alone. this is attributed to the high penetrating power of x-rays. let's explore some common faults that can be detected through x-ray pcb ...
