PCB Test Technology Selection: AOI, ICT, Flying Probe and X-ray Testing is the part of PCB production that decides whether a defect reaches the customer or is caught on the line. Every available method sees a different slice of the board, and none of them sees everything, so the useful…

PCB DFM Review Meeting: A Practical Manufacturing Guide 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 DFM review meeting from the perspective of a PCBA factory floor,…

PCB Design Revision Control: Design and Assembly Considerations 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 design revision control gives you a practical advantage when…

PCB NPI Checklist for A New Product: 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 NPI checklist for a new product…

Multilayer Board Faults: Shorts, Opens and Bad Vias A multilayer board that fails is usually failing for a reason that was designed in months earlier. Shorts, opens and intermittently connected vias rarely come from one bad process step; they come from clearance that was too tight, a via barrel with…

Double-Sided PCB: Definition, Structure and Applications A double-sided pcb occupies an unglamorous middle position in the market, and that is exactly why it ships in such volume. It costs far less than a multilayer stackup and offers far more routing freedom than a single-sided board, so it lands in the…

PCB Inspection Steps: How Boards Are Checked Before Shipping A finished board looks identical whether it was built carefully or merely plausibly. What separates the two is the inspection sequence behind it: a series of checks, each performed at the point where a defect is still cheap to correct. Understanding…

PCB Plating Types and Thickness: How to Choose a Finish Surface finish is one of the last decisions a designer makes and one of the first that assembly engineers ask about. It determines how well solder wets the pad, how long the board survives on a shelf, and whether a…

PCB Routing Rules: Current Path, Return Path, and Crosstalk Routing quality decides whether an electronic product performs, survives, and ships on schedule. The same schematic can produce a quiet board or one that resets when a motor starts, and the difference is almost always in the routing. The rules below…

PCB Routing Guide: Trace Width, Spacing and Return Paths Pcb routing is the stage where a schematic becomes physical copper, and it is where most of the electrical performance of a board is actually decided. Placement sets the possible solutions and the stackup sets the impedance, but the path each…
