Power Bank PCB: Charging, Protection and Layout What the Board Does A power bank board manages energy in both directions. On the input side it takes power from a USB charger, charges the lithium cell safely and reports the charge state. On the output side it boosts the cell voltage…

SMT Reflow Profile Verification Frequency: How Often to Verify 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 reflow profile verification frequency from the perspective of a PCBA…

Arlon PCB Materials: Grades, Properties and Selection What Arlon Materials Are Arlon is a family of high performance laminates rather than a single material. The name covers several different resin systems made for different problems: radio frequency circuits that need a low and stable dielectric constant, high speed digital boards…

Megtron 6 PCB: High Speed Low Loss Laminate What Megtron 6 Is Megtron 6 is a high speed, low loss laminate used for boards that carry fast serial links or high frequency signals. It is a filled resin system reinforced with glass fabric, and its value is in two electrical…

PCB Legend Curing Oven: Setting the Ink Properly 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 legend curing oven from the perspective of a PCBA factory floor,…

Switching Power Supply PCB: Layout Rules That Work Why the Layout Decides the Supply A switching supply is a schematic that almost never works as drawn. The circuit is simple, an inductor, a switch, a diode or a synchronous rectifier, a controller and a handful of capacitors, but the currents…

PCB Drilling Entry Material Selection: The Right Cover Sheet 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 drilling entry material selection from the perspective of a PCBA…

PCB Solder Paste Transfer Efficiency: Paste In, Paste Out 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 solder paste transfer efficiency gives you a practical…

Ultra-Thin Flex PCB: Design and Manufacturing What Ultra-Thin Flex Means An ultra-thin flexible circuit is a flexible board whose total thickness is measured in tens of micrometres. The dielectric is a polyimide film thinner than 50 micrometres, the copper is a thin foil, and the protective coverlay is thinner again,…

PCB Stencil Thickness Selection: How Much Paste the Opening Holds 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 stencil thickness selection gives you a practical…
