Abstract
In described examples, a device mounted on a substrate includes an encapsulant. In at least one example, an encapsulant barrier is deposited along a scribe line, along which the substrate is singulatable. To encapsulate one or more terminals of the substrate, an encapsulant is deposited between the encapsulant barrier and an edge of the device parallel to the encapsulant barrier.
Claims20
A device assembly comprising:
- a substrate;
- a device on the substrate, the device having an edge;
- bond wires electrically coupling the device to the substrate;
- an encapsulant barrier contacting the substrate;
- and
- encapsulant contacting the substrate, contacting the edge of the device, and on the bond wires, a portion of the encapsulant contacting the substrate between the encapsulant barrier and the edge of the device and the encapsulant barrier between the portion of the encapsulant contacting the substrate and an edge of the substrate.
