Drone Flight Controller PCBA Assembly and Sensor Test A drone flight controller board is compact and carries a large number of direction sensitive devices: the processor, the inertial sensors, the barometric sensor, memory, a crystal, the power section and several connectors. The packages are small and closely spaced, and some…

PCB Panel Size Selection: A Practical Review for Manufacturing Teams 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 Tooling Hole Placement: What Matters on the Production Line 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 Fiducial Placement: Markers for the Machine 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 fiducial placement from the perspective of a PCBA factory floor, covering putting…

Medical Monitoring PCBA Project Intake Checklist When a medical monitoring board moves from a prototype to a small production batch, the attention usually goes to the price and the date, and the programme, the test and the material revision are confirmed later if at all. What then appears after the…

PCB Test Point Accessibility: Key Process and Quality Checks 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 test point accessibility from the perspective of a PCBA factory…

HDI Fabrication: Stacked and Staggered Blind Vias As products become thinner and smaller, an ordinary through hole board runs out of routing space. The answer that HDI fabrication provides is to drill vias that do not pass through the whole construction: a blind via reaches from an outer layer to…

PCB Shield Frame Footprint: A Factory-Floor Review 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 shield frame footprint gives you a practical advantage when you…

Soldering Anomaly Investigation on an LED Driver Board An LED driver board can pass a visual inspection and then show a local temperature rise, an unstable output or a difference between boards from the same batch when the customer tests it. Replacing the power device is the common reaction and…

PCB Mid Mount Connector Design: From Design to Repeatable Production 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…
