What is Crazing

Crazing is a condition that can occur in the base material of a printed circuit board. It is characterized by the presence of connected white spots or “crosses” on or below the surface of the base material. These spots and crosses reflect the separation of fibers in the glass cloth and the connecting weave intersections.

Crazing is a phenomenon that typically affects the base material of a PCB. It is caused by the stress and strain that the material undergoes during the manufacturing process. The separation of fibers in the glass cloth and the connecting weave intersections can lead to the formation of these white spots and crosses on or below the surface of the base material.

Crazing can impact the overall quality and performance of a PCB. The presence of these spots and crosses can weaken the structural integrity of the base material, potentially leading to issues such as reduced mechanical strength or compromised electrical conductivity.
