Large Substrates

Challenge: Demand for Large and Rigid Printed Circuit Boards (PCBs)

As circuit boards become more complex, with greater numbers of components and modules on a single board, larger PCB substrates are required. Organic substrates are prone to warp as they increase in size, potentially hindering component performance. In contrast, ceramics offer high rigidity with much lower susceptibility to warping. Moreover, while large ceramic substrates are more challenging to produce, KYOCERA can supply substrates up to 320mm in length.
