PCB Conformal Coating Cure Verification: A Factory-Floor Review 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 conformal coating cure verification from the perspective of a PCBA factory…

EMC Design From the Layout Stage Many products discover that they do not pass electromagnetic compatibility testing late in development, and the correction takes several rounds, costs money and moves the launch date. The root of the problem is usually already present in the board, because a shield added over…

PCB Conformal Coating Thickness: Practical Process Controls 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 conformal coating thickness gives you a practical advantage when you…

BOM Optimization Methods That Reduce Material Cost Most of a product’s material cost is fixed while it is being designed, and the scope for reducing it later through purchasing is limited. Teams often focus on whether the function can be implemented and leave the cost of the bill of materials…

Impedance Control in PCB Manufacturing and TDR Testing As signal rates rise, the characteristic impedance of a trace stops being an incidental property and becomes a requirement. When the impedance along a path is not what the design intended, the signal reflects at the transition, rings, and closes the eye…

PCB Tin Whisker Growth: What Buyers and Engineers Should Check 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 tin whisker growth from the perspective of a PCBA…

PCB Delamination Causes: Design, Process, and Quality Notes 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 delamination causes from the perspective of a PCBA factory floor, covering…

Expedited SMT Service with 24-Hour Turnaround Product development runs to a calendar in which a day matters. A prototype that is verified a day later moves the launch date, and projects are frequently stuck waiting for a handful of assembled boards. What those projects need is not a promise to…

PCB Acoustic Microscopy for Delamination: 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 acoustic microscopy for delamination from the perspective of a PCBA…

Odd-Shaped Panel Design for Game Controller Boards A game controller board is shaped by the shell, the buttons and the way the product is held, so curved edges, narrow necks and asymmetric outlines are normal. The board also carries a main controller, a wireless module, a crystal, connectors and the…
