PCB Pad Cratering Analysis: When the Pad Lifts 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 Dendrite Growth Investigation: The Little Branch 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 dendrite growth investigation gives you a practical advantage when you…

High-Frequency PCB Material Selection and Processing Above roughly 1 GHz the laminate stops being a passive carrier and becomes part of the circuit. Losses in the dielectric, variation in the dielectric constant from batch to batch, and the quality of the copper surface all show up directly in insertion loss…

PCB Rinse Water Conductivity Control: Reading the Rinse 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 rinse water conductivity control from the perspective of a PCBA factory…

PCB CAF Failure Investigation: Growth Between the Layers 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 CAF failure investigation from the perspective of a PCBA factory floor,…

PCB Production Process: From Cutting and Drilling to Final Test A printed circuit board starts as a sheet of copper clad laminate and ends as a tested substrate with copper features measured in tens of microns. The PCB production process between those two points is a sequence of additive and…

Why 32 Layer Board Prototypes Cost More A high layer count board is expensive for reasons that go well beyond the price of the material. Each added layer multiplies the number of interfaces that must be bonded and aligned, lengthens every process step and reduces the proportion of boards that…

TVS Diode Selection and Placement for ESD Protection Every board that connects to the outside world needs a defined answer to the question of what happens when a discharge arrives. A transient voltage suppression diode is the most common answer, because it responds in fractions of a nanosecond, absorbs a…

PCB Solder Joint Crack Analysis: Following the Break 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 solder joint crack analysis from the perspective of a PCBA factory…

PCB Corrosion Failure Analysis: Where the Metal Went 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…
