Copper Clad Laminate: The Base of Every PCB Every rigid printed circuit board starts as a sheet of copper clad laminate: a woven glass cloth impregnated with resin, cured, and bonded to copper foil on one or both faces. The laminate is the dielectric, the mechanical structure and the thermal…

PCB RF Connector Layout: 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 RF connector layout gives you a practical advantage when…

PCB Antenna Clearance: 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 antenna clearance gives you a practical advantage when you choose…

PCB Balun Placement: Design and Assembly Considerations 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 Gasket Selection: 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 gasket selection from the perspective of a PCBA factory floor, covering choosing…

PCB RF Trace Impedance: 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 RF trace impedance from the perspective of a PCBA factory…

PCB Antenna Ground Plane Size: Process Details and Inspection Points 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 antenna ground plane size gives you a…

PCB Aperture in A Shield: Process Details and Inspection Points 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…

Incoming Inspection of Bare Boards: What to Measure and Record A batch of bare boards arrives, the box is opened, one board is held up to the light and the lot is accepted. That single glance is the whole of the receiving inspection process in many programs, and it is…

Solder Mask for Microwave Assemblies and Soft Soldering A microwave assembly is soldered with the same tools as any other board, but the requirements are different in one important respect: the solder mask is no longer only a protective coating, it is part of the electrical environment. At frequencies above…
