[Tweet](https://twitter.com/share) [Military](https://www.epectec.com/cable-assemblies/military-wire-harnesses.html) and aerospace systems operate in some of the harshest environments imaginable. Whether installed on a military ground vehicle, commercial aircraft, unmanned aerial system, naval vessel, or satellite subsystem, cable assemblies are routinely exposed to vibration, shock, temperature extremes, moisture, harsh chemicals, and electromagnetic interference. In these applications, reliability is not simply desirable, it is essential.

The earlier these process indicators can be identified in the PCB fabrication process, the greater the ability to avoid financial risk with the PCB builds. In high-reliability applications, waiting until final inspection to catch defects is too late. By that point, time, materials, and labor have already been invested, and the [cost of rework](https://www.epectec.com/services/rework-services.html) or scrap can be high.

On the surface, it may seem like a simple sourcing issue. One part went obsolete, so you find another one and move on.

You know how much circuitry is packed inside, how many tradeoffs were made, and how much risk sat in every design decision. Yet the finished product is thin, light, and deceptively simple. That contrast is what makes high-density flex design so rewarding and so challenging at the same time.

In reality, a stored battery pack is still changing over time. The cells continue to [self-discharge](https://blog.epectec.com/external-battery-storage-the-chemistry-and-state-of-charge), the pack continues to age, and the storage environment can affect the condition of the pack long before it is installed into equipment.
