Stacked Via: 5 Rules for HDI Reliability A stacked via is a microvia placed directly on top of another microvia, so the connection passes through two or more HDI layers without a landing pad between them. The arrangement saves the space that an offset or staggered build would need, which…

PCB Expedite Checklist: From Design to Repeatable Production 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…

Solder Fountain: 5 Rules for Selective Soldering A solder fountain is the small, localised wave that a selective soldering machine raises under a single through hole component, and its height decides how much of the barrel the alloy touches. Setting that height is more delicate than it looks, because the…

PCB Expedite Selection: What Buyers and Engineers Should Check 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 expedite selection gives you a practical advantage when…

PCB Expedite Control: Keeping the Schedule Steady An expedite request rarely fails because the line is slow. It fails because the compressed schedule exposes every open point at once. Files that were never fully checked, materials that were not in stock and approvals that waited too long all surface on…

PCB Expedite Improvement: A Practical Manufacturing Guide 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 expedite improvement gives you a practical advantage when you choose…

PCB Expedite Traceability: A Practical Manufacturing Guide 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 expedite traceability gives you a practical advantage when you choose…

PCB Expedite Environment: Design and Assembly Considerations 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 expedite environment from the perspective of a PCBA factory floor, covering controlling…

PCB Expedite Timing: Process Details and Inspection Points 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…

Nanocoating: 5 Rules for Stencil Paste Release Stencil nanocoating is a thin film applied to the aperture walls of a laser cut stencil so that solder paste releases cleanly rather than smearing down the side of the opening. On a stainless steel stencil that has no coating, the striated edge…
