Naming Gerber files: a skill nobody teaches. 📁 Which one did you actually upload? 👀 Our quote page previews whatever you upload. That's the moment to find out which "final" it was, not when the boards arrive. #EngineeringHumor #JLCPCB

Keep parts and traces away from the board edge. 📏 Routing the outline can damage anything that sits too close. For JLCPCB orders, keep copper at least 0.2 mm from routed edges and 0.4 mm from V-cut edges. More is safer. #PCBDesign #DFM #JLCPCB

Me: I'll just move this component 2 mm. Also me: Re-routing half the board. Tell us about your biggest layout meltdown.

Every off-center part has an origin story. 📍 Origin on pad 1? Your CPL may list that as the part's center, so the machine centers every copy on pad 1. The one origin story you want spoiled: check our placement preview. #EasyEDA #JLCPCB

Your PCB's spa day 🧖 🌡️ Warm-up: to about 150°C, 1–3°C/s 🧖 Sauna: 150–200°C, 60–120 s 🔥 Hot plunge: 230–250°C peak ❄️ Cool-down: steady, 2–4°C/s Before you order, check each part's max reflow temp in its datasheet. #PCBA #Reflow #JLCPCB

Forecast: humid. Your PCB: brought a raincoat. ☔ It's conformal coating, a thin acrylic layer that helps keep out moisture and dust. On Standard PCBA, we coat the whole board unless your order remark says otherwise (with images). #PCBA #JLCPCB

Controlled Impedance Is More Than Trace Width! Stackup, dielectric, copper thickness, and reference planes all affect impedance. Keep planes continuous and design for your target impedance. #PCBDesign #HighSpeedDesign #JLCPCB

What is Via-in-Pad? 👀 A via placed directly inside a component pad can help save PCB space and simplify routing in compact designs. Want to learn more about this PCB design technique? Save this video for later! 📌 Read more about via-in-pad: jlcpcb.com/help/article/via-… #JLCPCB

Tried adding resistors to connect I2C & UART. We tried to talk, but we still can’t understand each other. We’re done. You don’t get me at all. Just for fun, resistors won’t save this 😂 #ElectronicsMeme #JLCPCB

How does a thin PI heater generate heat? 🔍 A patterned metal trace converts electrical energy into heat as current flows. PI films provide insulation, while lead wires connect the heater to a power source. Learn more 👇 jlcpcb.com/blog/what-are-fle… #Engineering #FlexibleHeater

LDO capacitors do more than filter noise. ⚡ They also help with load transient response and loop stability. But bigger isn't always better — the right capacitance and ESR depend on the LDO datasheet. Don't overlook those caps! #JLCPCB #PCBDesign #electronics

A 10 Euro cent for scale. 📏 01005 components. 0.5mm FPC. 3x3 BGA. Our SMT machines place them all with absolute precision. 🤖 What's the smallest package you've hand-soldered? 👇 #PCBDesign #SMT #JLCPCB
The image shows a white JLPCB circuit board featuring two FPC connectors, labeled with various component specifications including "01005," "0402," "0603," "RF coupler," "TVS/ESD," and "Balun." A 10 Euro cent coin is placed beside it for scale.

Your 4-layer board went through a press like this. 🔥 Inner core + prepreg (resin-soaked glass fabric) + copper foils, under controlled heat and pressure. The resin fills the gaps, cures, and fuses it all into one board. #MultilayerPCB #JLCPCB

Avoid sharp acute angles in your traces. 📐 They can trap etchant in fabrication (acid traps). Use 45° turns or smooth curves. Before you order, our free JLCDFM check reviews your traces, drilling, solder mask and silkscreen. #PCBDesign #JLCPCB

Show this BGA layout to a 1995 engineer. 🤯 Then: weeks, labs, big budgets. Now: EasyEDA + JLCPCB → thousands of traces, BGA fanout, ENIG finish. A fraction of the cost and time. What was your first PCB, and what did it cost? 👇 #HardwareDesign #PCBA #JLCPCB #FPGA

Economic or Standard PCBA? Your board decides. 🤔 Go Standard for: ✅ Parts on both sides ✅ IC pin pitch below 0.4 mm ✅ BGA pitch below 0.5 mm Single-sided, nothing that fine? Economic keeps it simple, no edge rails needed. #PCBA #JLCPCB
