PCB Corner Bond for BGA: Holding the Corners 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 Dispensing Process: Filling Under the Die Underfill is a filled epoxy that flows into the gap between a die and its substrate. It spreads by capillary action and then cures into a stiff layer. That layer shares the stress that thermal cycling puts on the solder bumps. The…

Power Plane Inset and the 20H Rule Open a well-designed multilayer board and the power plane is often slightly smaller than the plane above or below it. The difference is deliberate. It exists because the field between a plane pair is not entirely contained inside the board: at the cut…

PCB Stencil Aperture Cleaning Method: Clearing the Apertures 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 aperture cleaning method gives you a practical advantage…

PCB Solder Paste Shelf Life Control: Using It In Time 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 shelf life control gives you…

PCB Floor Life Tracking: Counting the Hours 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 floor life tracking from the perspective of a PCBA factory floor, covering…

Dry Pack and Desiccant Selection for Moisture-Sensitive PCBs 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 dry pack and desiccant choice from the perspective of a PCBA…

Black Hole Process and Electroless Copper Compared A drilled hole is not yet a connection. The wall of the hole is laminate, and laminate does not conduct, so before any copper can be electroplated onto it the surface has to be made conductive by some means. Two families of process…

PCB Moisture Sensitivity Level Handling: Baking Before Reflow 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 Ionizer Use on the Line: Neutralising the Charge 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…
