PCB Shelf Life Extension: Keeping the Finish Solderable 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 Surface Finishes Compared: ENEPIG, OSP, ENIG, Tin and Silver Why the Finish Matters More Than It Looks Bare copper oxidises quickly. Left unprotected, a pad that measured perfectly on the artwork becomes difficult to solder within days, and the resulting joints are weak, resistive and inconsistent. A surface finish…

PCB Baking Before Shipment: Driving Out the Water 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 baking before shipment gives you a practical advantage when…

High-Speed PCB Manufacturing: China vs US Comparison Why This Comparison Keeps Coming Up High speed boards are the ones that carry the bandwidth: 5G radio units, AI compute nodes, network routers and high speed storage. The manufacturing requirements are stricter than for a general purpose board, and the price difference…

PCB Carton Stack Height Limits: How High to Stack 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 carton stack height limits gives you a practical…

Duroid PCB Material Selection and Fabrication Guide Material Choice Sets the Ceiling on RF Performance Below a few hundred megahertz, laminate choice is mostly a mechanical and cost decision. Above roughly one gigahertz it becomes an electrical one. Dielectric loss converts signal energy into heat, dielectric constant variation shifts impedance,…

PCB Edge Protection in Transit: Cushioning the Corners 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 edge protection in transit from the perspective of a PCBA factory…

Converter PCB Cost: Prototype to Volume Breakdown Why Converter Boards Cost More Than Control Boards A converter board moves energy between voltage levels or between alternating and direct current. Compared with a plain control board of the same layer count it means heavier copper, a denser thermal layout and more…

PCB Shipping Damage Prevention: Getting the Board There Intact 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 shipping damage prevention from the perspective of a PCBA factory…

Metal Stiffeners for Flexible PCBs: Selection and Assembly Local Rigidity in a Flexible Design Flexible circuits solve the problem of routing interconnect through confined, curved or moving spaces, but flexibility is not wanted everywhere. Connectors need to sit at a controlled height. Component pads need to stay flat through reflow.…
