[Tweet](https://twitter.com/share) When [battery packs](https://www.epectec.com/batteries/) are placed into storage, it is easy to assume they will be ready whenever they are needed. 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.

A design might look perfect on paper, but without clear workmanship standards and acceptance criteria, the final product can vary from build to build. That is exactly why IPC/WHMA-A-620 exists.

Industrial control panels, medical equipment, automotive sensors, laboratory instruments, and outdoor electronics all depend on strong strain relief, dependable sealing, and repeatable performance. Overmolding delivers that performance by encapsulating the connection point between the cable and its component interface, creating a unified structure that protects against moisture, vibration, abrasion, and general wear.

Devices get smaller, components become more numerous, and weight becomes an increasing concern. And while flex can be used to drop down the weight of a design, that only solves one of those three problems.

One technology that makes compact layouts possible is the use of [blind and buried vias](https://blog.epectec.com/pcb-vias-everything-you-need-to-know), specialized interconnections that don’t completely pass through the board like traditional plated-through-holes.

These systems can activate safety controls when problems arise while logging data that you can use to evaluate the cell's stability. When functioning properly, the BMS can improve the efficiency and longevity of the [battery pack](https://www.epectec.com/batteries/). Unfortunately, BMS design flaws may cause serious risks and failures to cells.

It is an easy conclusion to draw. High-volume manufacturing often dominates industry conversations, and many suppliers structure their operations around scale. But the reality is very different for companies like Epec, which specializes in high mix, low/medium volume-engineered products like PCBs.

In reality, stiffeners can be applied to [rigid-flex designs](https://www.epectec.com/flex/design/) just as they are in flexible circuits.
