Introduction The exposed surface area of many of today’s high-powered electronic packages is no longer sufficient for the removal of the heat generated during normal operation. Heat sinks are a commonly-used, low cost means of increasing the effective surface area for dissipating heat by means of convective air cooling. While the use of a heat sink lowers the fluid-side … [Read more...]
Statistics Corner: Modifying Sample Size
ABSTRACT Reliability verification often requires that a specific number of components be tested to a predetermined level of testing to demonstrate that none of the samples fail. This article describes a statistical approach for justifying the use of fewer samples by subjecting them to a more severe level of testing. BACKGROUND Reliability verification often includes … [Read more...]
Statistics Corner: Probability
Statistical analysis is needed because data always have some degree of uncertainty; a value that we determine from a single measurement, or even set of measurements, is not necessarily going to tell us exactly what value we will determine with additional measurements. Statistical analysis uses the mathematics of probability to create tools that we can use to deal with … [Read more...]
What Role Does PCB Copper Balance Play in PCB Fabrication?
PCB Fabrication is the process of building a physical PCB from a circuit board design by following the prescribed set of specifications. The understanding of the design specifications is very significant as it affects the PCB’s manufacturability, performance, and production yield rate. One of the vital design specifications to be followed is the ‘copper balance’ in the PCB … [Read more...]
