So, delays in any sort of complex hardware project often feels unavoidable. But sometimes, the bottleneck factors are just hiding in plain sight. Likewise, one of the most overlooked issues lies in your PCB footprint library. Now, that hits the mark! Incomplete, inconsistent, or any outdated libraries extensively slows down your entire ECAD workflow. Meanwhile,

Imagine your simulated circuit operates without any issues. The prototype looks flawless. But, the calamity hits: The arrival of tolerance-minimum resistors combined with temperature variations exceeding specifications leads to catastrophic failure of your previously “proven” design. Only because of these scenarios, NASA implements 400% safety margins to spacecraft electronics, while medical devices go through harsh

So, let me tell you a story that still stings today. We were working hard to meet a tight deadline for a client and making haste in delivery. But a tiny blunder in our PCB design cost us over $10,000 to redesign it and led to further delays. Ofocurse, a harsh punishment, wouldn’t you say?
Top 3 PCB Design Mistakes That Cost You Thousands Read More »
You spent months creating your flawless PCB but testing revealed its failure because traces melted down, components heated up, and signals became chaotic. Frustrating, right? You’re not alone. Even experienced engineers and hobbyists can experience PCB failures which affect designers, who take great care with their designs. What’s the truth? Small oversight mistakes lead to

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.

HDI PCBs play a crucial role in modern automotive touchscreen modules by managing electrical signals, power, and heat to ensure optimal performance.
They route electrical signals from the touchscreen sensors to the control processor through multiple layers. This routing is essential for handling different types of signals, such as touch inputs and display data.
When a user interacts with the touchscreen, sensors detect touch coordinates and transmit this data through the PCB’s signal paths to the processor, which then adjusts the display accordingly.
Precise signal routing ensures that touch inputs are accurately detected and processed, providing a responsive user interface.

After assessing the impact, the next step I always take is to run Design Rule Checks (DRC).
Early in my career, I made the mistake of thinking that small layout adjustments wouldn’t trigger any issues with DRC. But as I quickly learned, even the tiniest changes could result in violations of clearance rules or affect trace width.
