PCB Foam Insert Selection: The Foam That Holds Them 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 foam insert selection from the perspective of a PCBA factory…

PCB Structural Design: Board Size, Placement and Thermal Structural design is the part of the layout that is settled before routing begins: how large the board is, how the components are arranged on it, how the supply is decoupled and how heat leaves the assembly. These decisions constrain everything that…

PCB Drop Test for A Board: Letting It Fall 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 drop test for a board gives you a…

High Current PCB Design: What Works And What Fails A board that has to carry a hundred amps or more is a different design problem from one that carries a few amps, and the difference is not linear. Doubling the trace width does not double the current a board can…

PCB Shock and Vibration Test: Proving the Pack 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 shock and vibration test gives you a practical advantage…

PCB Vacuum Bag Sealing: Taking the Air Out 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…

Solder Pot Maintenance: Contamination, Dross and Alloy Control A solder pot is a reservoir of molten metal that dissolves everything it touches. Over weeks of production it accumulates the metals from the boards, the components and the plated finishes that pass through it, and its composition drifts away from the…

SMT Line Balancing and Takt Time in Production A surface mount line is a chain of machines, and a chain moves at the speed of its slowest link. Line balancing is the practice of matching the work at each station so that no machine waits and no machine becomes a…

Heavy Copper Traces: Sizing for Current and Thermal Rise Heavy copper is specified when a board has to carry tens of amperes rather than a few hundred milliamps, and the decision changes the fabrication process as much as the layout. Thicker copper etches differently, laminates differently and plated differently, so…

Connector Selection: Five Parameters That Decide Reliability A connector is the one component on a board that is designed to be connected and disconnected, and it is often the part that fails first. Connector selection means answering five questions, and the answers interact: a part chosen for its high speed…
