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: Where the Probe Lands 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 floor,…

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: The Ring on the Board 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…

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: A Hole for the Plug 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…

High Speed PCB Design for DDR, PCIe and USB 3.0 As product performance rises, high speed interfaces have moved from specialist designs into ordinary ones. A memory bus, a serial expansion link or a fast USB port appears on boards that would not have had one a few years ago,…

PCB Solder Wicking Into Vias: Where the Paste Goes 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 solder wicking into vias from the perspective of a PCBA…

Turnkey SMT Service With Component Procurement Buying the components and getting the board assembled are two separate problems that both consume attention. The parts have to be sourced from a supplier that can be trusted, the prices compared, the material verified, and the assembly then has to be tracked through…

PCB Pad Size for Hand Soldering: Leaving Room for the Iron 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.…
