WebApr 11, 2024 · The CTE values of the via filling and dielectric material should be equivalent to avoid stress fractures due to expansion. Plating thickness and via-in-pad specification, if any. ... Hence, this can further increase the cost and turnaround time of your PCB. Via-in-pad Filling of microvias in HDI boards. Staggered and stacked microvias. WebThe coefficient of thermal expansion (CTE) measures how much a material expands when exposed to high temperatures. In PCB design, it’s ideal for the dielectric layers to have a similar CTE to that of the copper layers. That way, if the layers expand, they do so in a uniform way that leads to minimal damage.
WebWhile they are more expensive, polyimide PCBs offer impressive flexibility and functional benefits over traditional FR4 boards. Lightweight, flexible and durable, polyimide PCB boards have the potential to solve many PCB integration and design problems, making them cost-effective in the long run. WebThe CTE value shows the thermal expansion of the base material. CTE-z represents the z-axis and is e.g. due to the stability of the vias, of high importance. A higher Tg value favors a low CTE-z value which represents the absolute expansion in the z-axis.
