Motion Sensor PCB: Sensors, Layout, and Power Budget Automatic lighting, security cameras, gesture control, and industrial safety systems all depend on the same underlying function: noticing that something moved. The board that does the noticing is built differently from a power or control board, because it has to sense a…

PCB Copper Roughness and Loss: Practical Process Controls Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB copper roughness and loss from the perspective of a PCBA factory…

PCB Panel Utilisation: Practical Process Controls 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 panel utilisation gives you a practical advantage when you choose a…

PCB Plating Thickness in A Barrel: From Design to Repeatable Production Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB plating thickness in a barrel from the perspective…

Drone PCB Cost: What Drives the Price of Flight Controller Boards Drone PCB cost is shaped by constraints that have nothing to do with the circuit: weight, vibration, thermal extremes and a very small available volume. A flight controller board is usually 30 to 50 millimetres square and carries a…

Video Recorder PCB: Design for High Speed Video Capture A video recorder board is a small system that happens to be shaped like a circuit board. It has to capture a high bandwidth data stream from an image sensor or a video decoder, process it, buffer it, write it to…

Laptop PCB Design: Layer Count, Space and Thermal Limits A laptop main board is one of the densest products in consumer electronics. It carries a processor with a thousand or more connections, a memory interface running at multi-gigabit rates, several high-speed serial links to the display and the storage, a…

PCB Differential Pair Skew Matching: Keeping the Two Halves Together Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB differential pair skew matching from the perspective of a…

PCB Loss Tangent at High Frequency: A Practical Manufacturing Guide 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…

PCB Traces: Structure, Materials and Design Rules A trace is a copper conductor manufactured by etching away everything around it, and its shape is the whole of its electrical behaviour. Width, thickness, length and the distance to its reference plane determine resistance, inductance, impedance and how much it disturbs its…
