PCB TDR Measurement Cost: What It Adds Up To 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 TDR measurement cost gives you a practical advantage…

PCB Microsection Data: What the Numbers Say 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 microsection data gives you a practical advantage when you choose…

Microetch Control: 5 Rules for a Bondable Copper Surface Microetch control prepares copper for the next layer by removing oxide and a thin film of metal at the same time. The etch is deliberately small, and that is exactly why it is easy to neglect, because a bath that has…

Barrel Plating Control: 5 Rules for Small Parts and Pins Barrel plating control matters wherever small parts are plated in bulk, from press-fit pins to connector shells and shield cans. The parts tumble against each other, so the current path, the contact and the load size all change constantly during…

PCB Microsection Risks: What Could Go Wrong 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 microsection risks gives you a practical advantage when you choose…

PCB TDR Measurement Control: Holding It Steady 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…

Underfill Flow Control: Filling the Gap Under a Package Underfill is a filled polymer dispensed along the edge of a package and drawn into the gap beneath it by capillary action, where it cures and couples the package, the solder joints and the board into one structure. Its purpose is…

PCB TDR Measurement Problems: When It Goes Wrong 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 TDR measurement problems gives you a practical advantage when…

Vapor Phase Reflow: Heat Transfer and Profile Control Vapor phase reflow heats a board by condensing a boiling liquid onto it, so the surface of the assembly is held at the boiling point of that liquid while the whole mass catches up to the same temperature. The mechanism differs from…

Etching Factor Control: Getting Straight Copper Sidewalls The etching factor is a number describing how close an etched conductor comes to a rectangular cross section, and it is one of the few figures that ties imaging, plating and etching together in a single measurement. A high factor means a sidewall…
