PCB Hole Tolerance: How Close the Drill Comes 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 explains…

PCB Fabrication Lead Time: Standard and Expedited Schedules A PCB fabrication lead time only means something when the board type, the process and the quantity are attached to it. A two layer prototype and a ten layer board with buried vias are not on the same clock, so a single…

PCB Edge Quality Requirements: What the Customer Sees 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 explains…

PCB Board Thickness Selection: How Thick Should It Be 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 board thickness selection from the perspective of a PCBA factory…

Security Camera Main Board PCBA Assembly A camera main board has to handle three things at once: the image, the network and the power. It carries a processor, memory, the network interface, the power conversion, the image sensor interface and the control circuit for the infra-red illumination, and the assembly…

PCB Panel Array Layout: Making the Best Use of Space 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 array layout gives you a practical…

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: Fitting the 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 article explains PCB…

PCB Tooling Hole Placement: Holding the Panel Still 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 explains…

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…
