🫨 A relay and a MOSFET can both be used to switch power, but they do it using completely different physics.

A mechanical relay energizes a coil and physically moves contacts. A MOSFET has no moving contact; a voltage at its gate controls a semiconductor path between drain and source.

That difference changes switching speed, isolation, drive behavior, lifetime considerations and where each device makes sense in a circuit.

Same basic job: control a load. Very different component.

Follow LionCircuits if you want components to make sense before they land on your PCB.

🤨 A tiny charger is doing a lot more than passing electricity from the wall to your phone. It is converting AC to controlled DC, negotiating the voltage and current your device can accept, switching power at high frequency, and getting rid of the heat that still remains when efficiency is less than 100%. That is why modern high-power chargers are such dense little electronics systems.

Follow LionCircuits if you want to understand what is actually happening inside the electronics you use every day.

A PCB can look right on-screen and still fail the most basic test: the real component has to match the footprint underneath it.

Before ordering, compare the exact package, pitch, pin numbering and orientation with the manufacturer’s datasheet. A quick physical-fit check can save a very expensive board revision.

Send this to someone designing their first PCB.

Why put components on both sides of a PCB?

Because board area is not free.

Keeping SMD parts on one side usually makes assembly simpler. Using the back can help when space is tight or when a part needs to sit close to something electrically important. The tradeoff is that the second side adds assembly processing and inspection considerations.

So this is not a one-side-good, two-side-bad rule. It is a design-for-manufacturing decision.

Save this before your next layout.

Via in pad can solve a routing problem and create an assembly question at the same time.

If the via remains open inside a solder pad, molten solder can wick into the hole during reflow. That can leave less solder available at the joint.

A filled and capped structure is one common controlled approach, but the final choice should follow the package guidance and your fabrication process.

Save this before your next dense BGA or leadless layout.

Tiny part. Very visible problem. 👀

If one side of a small resistor or capacitor wets and pulls before the other during reflow, the component can lift and stand on one end. That defect is called tombstoning.

Common things to check: solder-paste balance, part placement and uneven heating during reflow.

Save this for your next PCBA review.

79 years ago, we won our independence.

Today, we’re building the next kind of freedom — the hardware kind.

Every PCB we fabricate and assemble here is another step toward an India that doesn’t just consume technology, but builds it.

Not just Made in India.
Engineered in India.
Built for what’s next.

Happy Independence Day from all of us at LionCircuits. 🦁🇮🇳

The copper traces on your PCB are not drawn on. They are what is left after everything else is removed 🤯

The board starts with copper covering every single millimetre of its surface. A light sensitive coating goes on top. Your circuit design is exposed onto it using UV light. Then the board goes into an acid bath that eats away all the copper that is not protected. What survives is your trace pattern.

That is how every circuit board is made. Not printed. Etched.
