Your solder joints get more photos than we do. 📸

Our AOI cameras check for missing, wrong, reversed or shifted parts, bridges, and too much or too little solder. 3D AOI also measures joint height and volume.

Smile, 0402s. 😁

Breadboard: Great for testing. Terrible for high-speed signals.
Parasitic capacitance will destroy your SPI/I2C
Stop letting spaghetti wires hold your ESP32-S3 back. Get a real PCB.

Simplifies dense BGA routing but adds manufacturing concerns. Watch via filling, planarization, and solder joint reliability when choosing the process.
PCB engineers: What's your biggest trade-off with via-in-pad?👇

Long-distance relationships rarely work. Ask any differential pair. 💑

Constant gap, matched lengths, and noise cancels out.

At 480 Mbps, USB also wants 90 Ω. JLCPCB controls impedance from 4 layers up (±10%).

When your I2C bus has nothing to say 🤐 Don’t try this on real hardware.

We tried amplifying money. Attenuating bugs went better. 🐛

Bugs aren't in our parts library, yet somehow they end up in every BOM.

Tag the teammate who'll call the last one a feature.

💎 Diamonds are forever.
But have you seen some engineers' "diamond rings"?
Ohm my!
You had me at Ohm. 💙💍
Would you wear it? 👀

Did you know JLCPCB can put multiple PCB designs on one stencil? 👀

💡An easy way to cut down setup fees & shipping costs!

1. Set "Multiple PCBs on One Stencil" to Yes
2. Let JLCPCB arrange it or you panelize it
3. Add a Stencil Remark

Hardware evolution. ⏳➡️🚀

Left: 1970s messy wiring.
Right: Modern high-density SMT PCBA.

With tiny boards like the ESP32-S3 taking over, precision is everything. 🛠️

Which era are you building in? 👇

The great Teardrop debate. 🛑

Some engineers can't sleep at night if there are no teardrops on the pads. Others think it's a waste of time.

Which side are you on? 👇

Me: same hoodie every day.
My PCB: full-color anime art. 👕🎨

Multi-color silkscreen:
✅ Export the Gerber from EasyEDA Pro
✅ White 2- or 4-layer boards, ENIG
✅ With assembly? Panelize with edge rails, or the color won't print

Red zone. High density. 🚨
Pure routing ASMR with a tech beat. Turn your sound on. 🎧
What BPM does your brain run at when routing a board this dense? 👇

How does a thin PI heater generate heat?
A patterned metal trace converts electrical energy into heat as current flows through it. PI films electrically insulate the trace, while lead wires connect it to a power source.

Hook I2C to UART and all you get is gibberish. Two serial interfaces, totally different languages.
Just for fun, don’t build this 😂

Ding ding ding! 🛎️ It’s the Crystal Oscillator! ⏰
It's not just a component; it's the team's official Metronome. Without it, the "Brain" (STM32) literally won't know what time it is. 💀
(Shoutout to everyone who guessed it!)
