The right contract PCB assembly manufacturer is the one that accepts clear responsibility for material sourcing, assembly, inspection, testing, traceability and engineering changes—not simply the company with the shortest quotation. Buyers should define those boundaries before the first build because most expensive PCBA problems appear in the gaps between the BOM, placement data, component availability, … [Read more…]
BNC is usually the better choice for fast cable changes, accessible test connections, and 75-ohm video systems, while SMA is usually better when compact size, threaded retention, or higher-frequency performance matters. That quick rule is useful, but it is not enough to specify a connector. The correct choice must also match impedance, cable type, mating … [Read more…]
Humidity doesn’t just make you uncomfortable. It can also shorten the life of your favorite electronic devices. Whether you carry your phone outside on a hot, muggy Indiana afternoon or use your laptop in a damp basement, moisture creates real risks for sensitive electronics. The good news is that a few simple habits can help … [Read more…]
A solder float test PCB evaluation requires a production-representative coupon, controlled molten-solder exposure, and PTH inspection against an invoked acceptance specification. A record that says only “288°C for 10 seconds, pass” omits moisture conditioning, solder contact, exposure count, hole construction, section location, and the disposition criterion. The test creates a steep temperature gradient from the … [Read more…]
Long lead times, supply chain disruption and reduced visibility across global manufacturing networks have prompted many electronics businesses to reassess where products are made. For years, offshore production offered attractive unit costs and access to large-scale manufacturing capacity. Today, businesses are taking a broader view of manufacturing performance. Reshoring electronics manufacturing is no longer driven … [Read more…]
Learning how to discharge a capacitor safely means removing stored energy through a controlled resistance and then verifying the remaining voltage with a correctly rated meter. Disconnect every energy source first. Do not bridge the terminals with a screwdriver or bare wire; the resulting current can create an arc, damage the capacitor or PCB, and … [Read more…]
Internet of Things (IoT) products depend on far more than connectivity and software functionality. Behind every connected device sits a printed circuit board (PCB) that must support reliable operation, efficient power consumption, wireless communication and long-term durability. As IoT hardware becomes smaller and more capable, PCB manufacturing plays a bigger role in determining whether a … [Read more…]
Pin in Paste is a through-hole reflow method that solders compatible THT components during the same oven cycle used for surface-mount parts. It can remove a separate wave, selective, or hand-soldering operation, but only when the component, plated hole, solder volume, stencil, and reflow profile are designed as one process. The method is most useful … [Read more…]
Isola IS550H is a halogen-free, high-reliability laminate and prepreg system for high-power, high-voltage and automotive electrification PCBs. Its published properties include a 200°C glass transition temperature, 400°C decomposition temperature, low total Z-axis expansion and resistance to conductive anodic filament growth. These attributes make the material relevant when long-term thermal and insulation reliability matter more than … [Read more…]
Poor PCB stackup decisions can introduce signal integrity issues that only become visible during testing or, worse, after deployment. In high-speed electronics, these problems are rarely isolated. They are usually tied to how layers were arranged, how materials were selected and how closely the design aligned with manufacturing realities. Stackup design sits at the centre … [Read more…]
