Ball Grid Arrays and BGA Heat Sinks

A ball grid array, or BGA, is a type of packaging used to mount a device like a microprocessor. They are used for integrated circuits. BGAs allow for the entire bottom surface of the device to be used rather than just the perimeter, while the leads are shorter on average which creates better high-speed performance. BGAs are made of many, many layers overlapping one another and can contain anywhere from one to one million of a variety of circuits, including but not limited to logic gates, multiplexers, flip-flops, etc. In general, ball grid arrays (sometimes mistakenly referred to as "bonded grid arrays") have high lead count, a remarkable effective density, and minimal inductance.

The BGA is derived from the PGA or pin grid array, which has a face covered or partially covered by pins which use a grid pattern. BGA packages can have an advantage over other packages due to a lower thermal resistance. Heat that is generated by the circuit flows more easily to the PCB or printed circuit board, which keeps the chip from overheating.

BGA heat sinks are available in multiple sizes for thermal management for low power applications. Like all heat sinks, BGA heat sinks can be customized and designed to your specifications according to your needs. Though some believe BGA stands for "bonded grid arrays," your custom ball grid arrays are sure to address whatever thermal management concerns your particular electronic device presents. Be sure that whatever company you decide on for your thermal management needs considers bga heat sinks for your application.

LED Lights and Heatsinks

Have you ever been curious why LED lights aren’t as hot as other types of lights? Given the popularity of LED lights these days, especially as many of us put up Christmas lights prior to the upcoming holiday, it is quite fascinating to consider the way in which LED lights deal with the issue of heat dissipation and management as compared to other types of lights.

The variation in heat produced by different types of lights is quite drastic. As measured by one online retailer, a halogen bulb operated at 327 degrees. A CFL was cooler at only 167 degrees, but the LED was coolest by far at only 107 degrees. Heatsinks keep LEDs cooler than the competition, allowing for my toddler to handle the lights on our Christmas tree without me worrying that he’s going to burn his hands (and taking away the worry that the tree may catch on fire!).

Heatsinks in general work to dissipate heat for any kind of electronic and not just lights. LEDs, however, are a perfect example to provide which most of us are familiar with, as everyone knows how hot an incandescent light bulb can get. Heatsinks can be designed in a nearly infinite array with variations provided to meet the different needs of the application. LED heatsinks, like all heatsinks, can be made from different materials with different structures meant to maximize surface area to release heat more efficiently. Many heatsinks utilize pins, fins and other components for the general purpose of thermal management.
