How to Rock a 3D CAD Modeling Workflow That Will Save You Tons of Time

Time is the universal currency.

We use time.

We save time.

However, time is a finite resource, and eventually, we all reach a point where it runs out.

As the saying goes, “Live as if today is your last day on earth,” reminding us of the importance of valuing the time we have and living with purpose.

In the automotive industry, especially when designing battery enclosures for electric vehicles (EVs), time-saving directly impacts efficiency, cost-effectiveness, and overall productivity.

A battery enclosure is a critical component in the design of electric vehicles (EVs), serving as the protective casing that shields the battery from external elements and internal hazards.

In the world of automotive design, the importance of these enclosures has only grown as electric vehicles become more advanced and more widely adopted.

Not only do they help maintain optimal battery performance, but they also ensure the safety, efficiency, and longevity of the vehicle’s power system.

The primary role of a battery enclosure is to protect the battery from physical damage and environmental conditions such as moisture, dust, or extreme temperatures.

These conditions can significantly impact the performance and lifespan of the battery if not properly managed.

Additionally, battery enclosures are designed to manage the thermal characteristics of the battery pack.

7 challenges make risky Towards Sustainable Automotive PCB Design

Ecad /

Automotive PCBs are built to handle a lot.

We’re talking extreme temperatures, high vibrations, exposure to oil, fuel, and humidity.

Now, when you move to sustainable materials—like halogen-free laminates or bio-based substrates—you’re taking a risk.

Not all eco-friendly materials are built to endure the severe environmental conditions inside a car, especially in areas like engine compartments or battery packs.

Ensuring these materials can withstand the high temperatures and mechanical stress typical of automotive environments is a key challenge.

2. Safety First – Does Sustainability Pass the Crash Test?

In automotive electronics, safety is non-negotiable.

Think about systems like Advanced Driver Assistance Systems (ADAS) or Battery Management Systems (BMS)—a failure here isn’t just inconvenient, it’s catastrophic.

Sustainable PCB materials need to meet the same stringent safety standards, such as ISO 26262 for functional safety, as their traditional counterparts.

The issue?

Some of these new materials haven’t been fully tested under the harsh conditions automotive systems demand.

Can they resist flame and heat?

Do they maintain performance over time?

Sustainability needs to prove it can keep up with safety first.

How to reduce the EMI and EMC in your PCB design Projects?

Analysis & Simulation /

A low-inductance ground plane is essential in PCB design for reducing electromagnetic interference (EMI) and mitigating signal integrity issues.
A larger ground area on the PCB reduces the system’s ground inductance, which in turn helps decrease EMI emissions and crosstalk.
While there are various methods to connect signals to the ground, it’s important to understand what should not be done.
• Never connect PCB components randomly to ground points.
• Use a Full Ground Plane and Ground Grids
• Minimize Return Path Lengths
Faraday’s law dictates that the return current should follow the path of lowest impedance.
Impedance at any given frequency is described by the formula Z(w) = R + jωL.
