HAST Test Setup: 5 Rules for PCB Reliability A HAST test puts a board or an assembly under high temperature and high humidity while it is electrically biased, and it is used to find humidity driven failure modes in days rather than in the months a steady state humidity test…

Panel Edge Control: 5 Checks Before Lamination Panel edge control is the set of checks applied to the outside of a panel before it enters the press, and it decides both how the panel presses and how it behaves afterwards. A burr, a chipped corner or a film of resin…

PCB Quotation Audit: From Prototype to Volume Production 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 quotation audit from the perspective of a PCBA factory floor, covering…

Boundary Scan: 5 Steps That Lift Test Coverage Boundary scan is a test method that uses the shift register built into a digital device to drive and read the pins around it. Instead of pressing a probe onto a net, the tester shifts a pattern through the chain and compares…

PCB Quotation Cost: 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 quotation cost from the perspective of a PCBA factory floor, covering costing quotation…

Finished Thickness: 6 Rules for PCB Tolerance Finished thickness is the dimension a board has after every fabrication step is complete, and it is the value that a connector, a card guide or an enclosure will actually see. It is not the laminate thickness ordered, and it is not the…

PCB Quotation Problems: 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 quotation problems gives you a practical advantage when you choose a…

Filter Cartridge Control: 5 Rules for Plating Baths Filter cartridge selection and change practice decide whether a plating bath deposits clean metal or transfers its contamination onto every panel. The filter is the only component on the line that removes particles continuously, and a cartridge that is too coarse, too…

PCB Quotation Checklist: 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 quotation checklist gives you a practical advantage when…

Orange Peel: 6 Causes in Solder Mask Finish Orange peel is the fine, dimpled texture that sometimes appears on a cured solder mask, named because the surface resembles the skin of a citrus fruit. It is a cosmetic defect in most cases, but it is also a signal that the…
