SMT Stencil Squeegee Pressure: How Hard the Blade Presses 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 SMT stencil squeegee pressure from the perspective of a PCBA factory…

PCB V-Cut Panelisation: Standards, Tolerances and Design Rules What V-Cut Does V-cut scoring is the fastest and cheapest way to separate rectangular boards from a panel. Two rotating blades cut a shallow V shaped groove into both faces of the panel along the line where the boards must separate, leaving…

PCB Copper Trace Resonant Frequency: When the Trace Rings 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 Manufacturing Yield: How to Reduce Defects and Raise Output What Yield Actually Measures Yield is usually quoted as a single percentage, but the useful figure is first pass yield: the proportion of panels or boards that pass every inspection and test stage the first time, without rework or repair.…

Copper Thickness for Flex PCB: How to Choose Why Copper Thickness Matters More on Flex On a rigid board, copper weight is mostly a question of current and thermal spreading. On a flexible circuit it is also a mechanical decision. The copper is bonded to a polyimide film, and the…

SMT Reflow Solder Joint Inspection Method: How the Joint Is Checked 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.…

IQC, IPQC and FQC: PCB Inspection Stages Explained Three Gates Between Material and Delivery Quality in board manufacturing is not achieved by inspecting the finished panel. It is achieved by checking the material before it enters the line, checking the product while it is being made, and checking it again…

PCB Surface Finish Nickel Thickness: How Much Nickel Is There 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 surface finish nickel thickness from the perspective of a…

SMT Component Reflow Self Centering: The Part That Slips Into Place 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 SMT component reflow self centering from the perspective of…

Paste Mask vs Solder Mask: How the Two Layers Differ Two Layers, Two Different Jobs The confusion between the paste mask and the solder mask comes from their names, which both describe a mask and neither of which says what it is for. The solder mask is a physical coating…
