PCB Threaded Insert Installation: Putting a Nut in the Board 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 threaded insert installation gives you a practical…

PCB Pin in Hole Reflow: Soldering a Connector by Reflow 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 pin in hole reflow gives you a…

PCB Corner Staking: Holding the Corners Down 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 corner staking from the perspective of a PCBA factory floor, covering adding…

BGA Underfill Process: Filling Under the Package 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 BGA underfill process gives you a practical advantage when you choose…

PCB Component Standoff Height: Lifting the Part Off the Board 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 component standoff height from the perspective of a PCBA…

PCB Capillary Solder Flow: How Solder Climbs 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 capillary solder flow gives you a practical advantage when you…

PCB Hole Wall Copper Thickness: Plating the Barrel 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 hole wall copper thickness from the perspective of a PCBA factory…

Layer Assignment in Multilayer Boards: Power, Ground and Signal Layer assignment is the part of multilayer design that is hardest to change later. Once the stack-up is fixed, the impedance of every controlled trace is fixed with it, the reference plane each signal returns through is decided, and the space…

PCB Annular Ring Measurement: How Much Copper Is Left 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…

Flex PCB Design: Materials, Bend Radius and Support A flex PCB is designed against a different set of constraints from a rigid board, and the difference is mechanical as much as electrical. The board has to bend without breaking, the conductors in the bend region have to survive repeated movement,…
