PCB Quality Agreement Records: 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 quality agreement records gives you a practical advantage when you…

PCB Quality Agreement Problems: When It Goes Wrong A quality agreement is the written promise that sits behind every purchase order. It states which defects matter, how they are measured, and what happens when a lot fails. When that document is vague, the argument starts after the boards arrive. The…

SPC Control Charts: 6 Rules for PCB Assembly Lines SPC control charts plot a measured characteristic from a PCB assembly line against time, with a centre line and a pair of limits that come from the process itself rather than from the drawing. When the points wander outside those limits,…

Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB quality agreement checklist from the perspective of a PCBA factory floor, covering…

Drill Regrind: Extending Bit Life Without Losing Quality Drill regrind is the process of restoring the cutting geometry of a used carbide bit so that it can be returned to production. Done properly, it extends the life of an expensive tool and keeps hole quality stable; done casually, it produces…

This guide looks at PCB quality agreement selection from the perspective of a PCBA factory floor, covering…

Blowhole Defects in PCB Soldering: 8 Causes and How to Fix Them A blowhole is a small gas pocket that has broken through the surface of a solder joint. It reads as a crater, a pinhole or a frosty blister on the fillet, and it is one of the few…

Reverse Pulse Plating: Better Copper Distribution in Holes Reverse pulse plating alternates a forward plating current with a short reverse pulse, so that copper is deposited and then partly dissolved in a repeating cycle. The purpose is not to plate faster but to plate more evenly, particularly in deep holes…
