6-Layer High Frequency PCB: Stack and Materials Why Six Layers Is the Common Answer A high frequency design that also has digital and power circuitry tends to end up at six layers. Two layers cannot give the radio frequency section a ground plane and the digital section a separate return;…

PCB Breakaway Tab Size: Strong Enough and Easy to Break 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 breakaway tab size from the perspective of a PCBA…

Nickel Flash Gold PCB: A Thin Gold Finish Explained What the Finish Actually Is Nickel flash gold is a plated finish of nickel with a very thin layer of gold on top, applied by the same electrochemical sequence used for electroless nickel immersion gold but with a much shorter gold…

PCB Mouse Bite Design: Small Tabs That Hold 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 mouse bite design gives you a practical…

16-Layer PCB: Stack-Up and Manufacturing Limits What Changes at Sixteen Layers A sixteen layer board differs from a twelve layer board by more than four layers. The board is thicker, the through vias are longer, the accumulated registration error across the stack is larger, and the number of process passes…

PCB V-score Depth Tolerance: Scoring the Board for Breaking 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 V-score depth tolerance gives you a practical advantage…

Standard MCPCB Thickness: How to Choose Two Thicknesses, One Confusion A metal core board has a metal base and a dielectric layer, and both have a thickness. When a specification says 1.6 millimetres it usually means the total, but the number that governs the thermal performance is the dielectric, and…

12-Layer PCB: Stack-Up, Design and Manufacturing What Twelve Layers Buys A twelve layer board is the point at which the design has stopped being an exercise in routing and become an exercise in planning. A circuit that needs twelve layers usually has several high speed interfaces, more than one supply…

PCB Punch Die Clearance: The Gap in the Tool 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 punch die clearance from the perspective of a PCBA factory…

PCB Leads and Wires: Selection and Termination The Connection Everyone Forgets Most of a design review is spent on the circuit, and the connection between the board and the rest of the product is treated as a detail. It is not. A solder joint between a stranded wire and a…
