Medical Electronics Development and Certification Support Medical equipment places demands on a design that consumer products do not. The function has to be correct, but it also has to be safe for the person using it, immune to interference from everything around it, and stable over years rather than months.…

PCB Common Mode Choke Design: A Practical Manufacturing Guide 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 common mode choke design from the perspective of a PCBA…

High Frequency Board Manufacturing on Rogers Material Fifth generation mobile networks, satellite links, millimetre wave radar and automotive radar have pushed high frequency circuit boards from a specialist item into a mainstream requirement. A high frequency board differs from an ordinary FR4 board in the material, in the processing and…

PCB Inductor Selection for A Regulator: Design and Assembly Considerations 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 inductor selection for a regulator gives you…

HDI Design With 1 to 4 Order Blind and Buried Vias Phones, tablets, wearables and high end industrial modules all rely on high density interconnect boards to fit the routing into the space available. Designing one is harder than designing an ordinary multilayer board, because the stack-up, the via strategy,…

PCB Bulk Capacitor Versus Ceramic: Process Details and Inspection Points 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 bulk capacitor versus ceramic from the perspective of a…

PCB Power Plane Resonance: 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…

Repeat Order Assembly of an Industrial Robot Control Board After a prototype has been verified, the usual next step is to order the same board again in a larger quantity. It looks like a matter of adding a zero to the quantity, but three things have often changed in between:…

PCB Star Ground Versus Ground Plane: What Matters on the Production Line 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 star ground versus ground plane…

Volume Assembly of an Automotive Body Controller Board A body controller board carries a main controller, a communication transceiver, a protected supply circuit, relays and several connectors. When a project like this is prepared for volume, the useful conversation does not start with the date the line can run. It…
