SPI Measurement Repeatability and Gauge Studies Solder paste inspection produces a number for every pad on a panel, and the value of that number depends entirely on how much of it is measurement and how much is noise. Repeatability is the part of the variation that comes from the machine…

PCB Panel Size Cost: From Prototype to Volume Production 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 panel size cost from the perspective of a PCBA factory…

PCB Panel Size Problems: Key Process and Quality Checks 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 panel size problems from the perspective of a PCBA factory…

PCB Panel Size Improvement: Key Process and Quality Checks 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 panel size improvement gives you a practical advantage…

Drill Bit Storage: Crib Control for PCB Tool Condition Drill bit storage is the part of the tool cycle that happens between resharpening and the machine, and it is where a surprising amount of damage occurs. A bit stored badly can arrive at the spindle already dulled or chipped. A…

Adhesion Promoter Control Before Conformal Coating: 5 Rules An adhesion promoter is a thin chemical layer applied between the board surface and the conformal coating. It provides the chemical bridge that the coating cannot form on its own, particularly on solder mask, on metal pads and on moulded parts. It…

Hot Bar Soldering Control for Flex to Board Joints: 6 Rules Hot bar soldering joins a flex tail to a rigid board by pressing a heated thermode onto the overlapping pads and melting the solder between them. The process is used where the joint count is high, the pitch is…

SMT Feeder Cart Setup: Staging for Fast Changeover A feeder cart carries pre loaded feeders to the placement machine so that most of the setup happens away from the line. On a high mix line it is the difference between a changeover that takes twenty minutes and one that takes…

Plating Anode Basket Control: Contact, Area and Loading An anode basket holds the copper that replaces what the tank deposits, and it is usually treated as a container rather than as a process component. The way it is loaded, hung and cleaned decides how evenly the current is distributed across…

Stencil Frame Condition: Mesh Bond and Frame Flatness A stencil frame holds the foil under tension, and the frame is what keeps the apertures in the right place at the right height. Its condition decides whether the printer can control the print at all. The frame is the part of…
