Have you ever spent a lot of time preparing your PCBA project, only to find that some components are difficult to source? Finding reliable suppliers, comparing options, and managing international shipments can be a time-consuming part of electronics production. To make this process easier, JLCPCB provides Global Sourcing service as one of its featured solutions. With professional sourcing support and supply chain resources, JLCPCB helps customers find suitable components and reduce the hassle of searching across multiple channels. You don’t need to spend extra time communicating with different suppliers or dealing with complicated customs procedures when sending components internationally. JLCPCB helps simplify the sourcing process and provides more support throughout your PCBA journey. From prototypes to small-batch production, reliable component sourcing can help you move your projects forward with greater confidence. #JLCPCB#PCBA #ElectronicsManufacturing#BOM

Have you ever finished a PCB project, only to realize you need another batch a few months later? The good news is: you don’t always need to upload everything again and repeat the whole process. With JLCPCB SMT Reorder, you can quickly reorder previous PCBA projects, reuse your existing production settings, and save time on repeated setup work. If your design hasn’t changed and the required components are available, getting your next batch ready becomes much easier. Whether it’s a small prototype update or a production refill, a simple reorder process can help you spend less time on paperwork and more time improving your product. #JLCPCB#PCBA #SMTAssembly

A PCB design can look perfect on your computer, but that does not always mean it will be manufactured smoothly. During PCB fabrication and PCBA assembly, engineers may encounter unexpected issues such as incorrect footprints, insufficient component spacing, soldering defects, or assembly limitations. Many of these problems are not caused by circuit design errors, but by manufacturing requirements that were overlooked during the design stage. This is where Design for Manufacturability (DFM) becomes important. DFM helps engineers evaluate whether a PCB design is suitable for real-world manufacturing before production begins. By identifying potential risks early, engineers can reduce redesigns, save development time, and improve production reliability. Common DFM checks include: Component spacing and placement PCB trace width and clearance Solder mask design Footprint compatibility SMT assembly requirements PCB panelization For example, a compact PCB may use many 0402/0603 components placed close together to save space. While the circuit may work correctly, insufficient spacing can increase the risk of solder bridging or make SMT assembly more difficult. A DFM review can help identify these issues before manufacturing. DFM is especially important for advanced PCB assemblies using QFN, BGA, and fine-pitch components, where small design mistakes can lead to expensive production problems. To help engineers check their designs before manufacturing, JLCPCB provides an online DFM Analysis Tool. Engineers can upload PCB design files and review potential manufacturing issues related to fabrication and assembly.

A manufacturable design helps ensure smoother production, better quality, and faster time to market.

I recently had a PCBA project where a few components weren't available in JLCPCB's parts library. Instead of redesigning the board or looking for alternatives, I decided to use the Consigned Parts service and ship my own components to JLCPCB for assembly. One thing I hadn't considered was the import process. Since the parts were being shipped to China, customs clearance was required, and I didn't have a customs broker to handle it. What impressed me was that JLCPCB's customer service reached out proactively and let me know they could assist with the customs clearance process. That made the whole experience much smoother than I expected. https://jlcpcb.com/help/article/how-to-consign-parts-to-jlcpcb If you're working with hard-to-find components, end-of-life parts, or parts you've already purchased elsewhere, the Consigned Parts service is definitely worth considering. It gave me much more flexibility, and the support throughout the process was excellent. Has anyone else used the Consigned Parts service? I'd love to hear how it worked for your projects.

I noticed that some resistors and capacitors I used to order have gone up in price recently, so I did a little digging. It turns out this isn't just happening on JLCPCB—it's affecting the entire electronics industry. With the rapid growth of AI hardware, many component manufacturers have shifted production capacity toward higher-demand products. As a result, the supply of general-purpose resistors and capacitors has tightened, pushing prices up across the market. From what I understand, JLCPCB simply follows the latest supplier pricing rather than adding extra markup. Hopefully, prices will become more stable as supply catches up. Has anyone else noticed the same thing?

When designing a PCB, sometimes the standard assembly process is just not enough. Maybe your LED needs an extra spacer to sit at the perfect height. Maybe your board needs a few wires soldered directly onto it. Maybe a component comes with a positioning pin that gets in the way, and you need it removed before assembly. These small details can become challenging during production. Luckily, I found a really useful feature on JLCPCB: PCBA Remark. During the PCBA order setup, simply go to: PCBA Parameters → PCBA Remark → Yes Then leave a detailed note describing your special requirements. For example: Add a spacer for LED1 (Part Number: ). Please install spacer model #123 to keep the LED at the required height. Solder a wire cable to connector J2 (Part Number:) according to the attached instructions. Remove the positioning pins from component U3 (Part Number: ) before assembly, then proceed with soldering. Perform manual soldering for component R5 (Part Number:) because it requires a special assembly method. After submitting the order, engineers will review your request, evaluate the manufacturing process, calculate any additional cost if needed, and send the details to you by email. No complicated communication. Just leave your requirements clearly, and the engineering team will help make it happen. As a hardware maker, I really appreciate this kind of flexibility. Not every project is a simple “upload files → assemble → done” process. Sometimes a product needs those small extra touches to become the final version you imagined. A simple remark can make a big difference. Have you ever needed a special PCBA process that wasn’t available in the standard options? Share your experience below!

One thing that can slow down a PCBA project is finding the right components. You may already have your BOM ready, but during the ordering process you might discover that some parts are unavailable or need replacements. Finding alternatives while keeping the same specifications can be frustrating. I recently learned about JLCPCB Parts Selection Service. You only need to upload your BOM and CPL files, and JLCPCB engineers can help recommend suitable components for your project. The service costs $10 for component selection, and this fee is only for selecting parts (PCBA manufacturing is charged separately). I think this is a great option for people who: Don't want to spend hours searching for replacement components Need help dealing with out-of-stock parts Want a smoother PCBA ordering experience Sometimes the hardest part of PCBA production is not making the board, but finding the right components. Having an engineer help with the selection process can save a lot of time. ##PCBA##
