PCB Gate Resistor Selection: Setting the Speed of the Switch 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 gate resistor selection from the perspective of a PCBA…

Polyimide PCB Material: Heat, Flex and Reliability Polyimide is the material that made the flexible circuit practical. It withstands soldering temperatures, it can be made in very thin films, it is mechanically tough and it is dimensionally stable when it is processed correctly. Those properties are why it is still…

PCB Shunt Resistor Placement: Where the Current Is Measured 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 shunt resistor placement from the perspective of a PCBA factory…

PCB Board to Board Connector: Two Boards, One Joint 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…

PCB Wire to Board Connector: Joining a Cable to a Board 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.…

PCB Fuse Holder Selection: Holding a Fuse Properly 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…

FPC Outline Design: Tolerances, Cutting and Panel Layout The outline of a flexible circuit is not a rectangle drawn around the circuit for convenience. It is a mechanical element that decides how the part is made, how it is handled and, in many products, how long it survives in service.…

IP Camera PCB Design: What the SoC Choice Changes An IP camera board is a compact system that combines an image sensor interface, a video processor, memory, a network interface and a power chain inside a housing that is often sealed. The device that gets most of the attention is…

PCB Snubber Design: Absorbing the Ring 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 snubber design gives you a practical advantage when you choose a…

PCB Solder Mask Repair: Process, Materials and Standards Every board shop produces a small number of panels with a local defect in the solder mask: a scratch, a pinhole, a small area of exposed copper. Scrapping the panel is the safe answer and the expensive one, so the industry has…
