PCB Lot Acceptance: Accepting a Delivery 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 lot…

PCB Rework Log: Recording Every Repair 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 rework…

PCB Certificate of Compliance: A Paper That Says It Matches 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 certificate of compliance gives you a practical…

PCB Transition Between Layers: Where the Line Changes Floor 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 transition between layers from the perspective of a PCBA factory…

Low Loss Materials for Millimetre Wave PCB Stack-Ups Above roughly thirty gigahertz the wavelength on a printed circuit board is measured in millimetres, and low loss material stops being an optimisation and becomes the starting point of the design. Every stub, pad and connector launch that was invisible at lower…

PCB Control Plan: Writing Down the Controls 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 Supplier Capability Audit: Looking at the Shop 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 supplier capability audit gives you a practical advantage when…

Panel Mounting and Soldering of Coaxial Connectors A coaxial connector that passes through an enclosure wall carries two joints at once. Inside the box it is soldered to the board, and at the wall it is mechanically fastened to the panel. Both have to work, and the electrical performance of…

Pick and Place Nozzle Selection, Wear and Maintenance Placement accuracy is usually credited to the machine, yet many placement faults trace back to the small consumable on the end of the head. The pick and place nozzle decides how firmly a component is held, how squarely it sits after release,…

Placement Accuracy: Feeder Setup and Fine Pitch Assembly Placement accuracy is usually discussed as a machine specification, quoted in micrometres and compared between vendors. On the line it is a system property, and the machine is only one of its parts. The feeder, the nozzle, the board support and the…
