Via in Pad Assembly and Void Control on Dense Boards Placing a via inside a component pad saves routing space and shortens the current path, which is why the technique is common on dense boards and around fine pitch packages. It also creates a hole directly beneath a solder joint,…

PCB Reflow Profile Cost: What It Adds Up To 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 reflow profile cost from the perspective of a PCBA factory…

PCB Test Strategy Design for Production A test strategy is the decision about what will be checked, at which stage, with which method, and at what cost, and it is made long before the first board is built. The decision determines the fixture, the test points, the layout of the…

PCB Reflow Profile Problems: When It Goes Wrong 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 reflow profile problems from the perspective of a PCBA factory floor,…

PCB Reflow Profile Training: Teaching the Team 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 reflow profile training from the perspective of a PCBA factory floor, covering…

Conductive Gasket Design For Shielded Enclosures A conductive gasket is the part that closes the gap between a shielded enclosure and its lid. The metal walls of the box carry the current, but the seam between two pieces of metal is not continuous, and at radio frequencies a discontinuity of…

PCB Reflow Profile Records: Writing It Down 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 reflow profile records gives you a practical advantage when you…

PCB Reflow Profile Selection: Choosing What Fits 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…

PCB Reflow Profile Checklist: What to Check 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…

Flex Stiffener: Design Rules and Process Limits A flexible circuit is thin by design, and that thinness is exactly what makes it useful. The same property makes it difficult to handle, to solder and to plug into a connector, so a piece of rigid material is bonded to the flex…
