Definition of Microelectronics

While there is no strict industry definition for "Microelectronics PCB", this category of PCBs is generally defined as having lines and spaces that are 0.002" (50 micron) or less.  They are also often associated with blind, buried, and/or stacked microvias.  Another cross reference is with HDI, or high-density interconnect PCBs.

Applications for Microelectronics

Microelectronics are used when devices need to be miniaturized. Applications include medical, military, telecommunications, and mobile.

Common Issues
