PCB Gold Plating Thickness on A Connector: How Much Gold to Plate Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for…

PCB Panel Fiducial for Placement: Finding the Panel First Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article…

PCB Nickel Barrier Under Gold: The Layer That Stops the Copper Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB nickel barrier under gold gives you…

Agriculture PCB Design for Smart Farming Systems Electronics in agriculture has to work where the environment is at its least cooperative. Sensors sit in soil and in weather, power comes from a battery charged by a small solar panel, connectivity is intermittent, and the equipment is expected to keep working…

Defense Systems PCB Manufacturing: Prototype to Production A defense systems PCB shares the reliability expectations of aerospace with a set of constraints that are entirely its own: long service life, small production quantities, strict supply chain control and documentation that may be reviewed years after the hardware was built. What…

Tin Plating on PCB: Flatness, Storage Life and Whiskers Tin plating is one of the flat surface finishes, and it is chosen for the same reason as immersion silver or organic preservative: it produces a coplanar surface that fine-pitch assembly requires, at a cost between the cheapest organic finish and…

TG130 PCB: Where a 130 Degree Laminate Still Works The TG130 PCB laminate is the entry point of the high temperature range. It is a standard epoxy glass material with a glass transition temperature of about 130 degrees Celsius, and it remains in wide use because most boards never need…

Smart Sensor Circuit Board: Structure and Key Technology A smart sensor is a device that measures something, processes the measurement and reports a result that has already been interpreted. It differs from an ordinary sensor in that the conversion, the compensation and often the decision logic all sit inside the…

Flight Controller PCB: Sensors, Vibration and Power Filtering A flight controller PCB is the board at the centre of a drone or an unmanned aircraft, and it has an unusual set of requirements. It has to read a set of inertial sensors accurately enough to estimate the vehicle attitude, run…

Security System PCB: Basic Knowledge Explained A security system is defined by the fact that it must work when everything else has failed. The power may be out, the network may be down, a cable may have been cut deliberately, and the system still has to detect, record and report.…
