pga pin grid array package

pGA chip packaging is commonly used in the packaging of microprocessors. Generally, the integrated circuit (IC) is packaged in a ceramic chip. The bottom of the ceramic chip is arranged into square pins. These pins can be inserted or soldered to the circuit board The corresponding socket is very suitable for applications that require frequent wave insertion. For chips with the same pin, the pGA package usually requires a smaller area than the conventional dual in-line package.

The pGA package has the characteristics of more convenient plug-in operation, high reliability and adaptability to higher frequencies. The early pentium chips, 80486, pentium, and pentiumpro in the InTel series CpU all adopt this package form.
BGA ball grid array package
The BGA package is improved from the pGA pin grid array. It is a packaging method that covers a surface with a grid pattern to cover the pins. When in operation, it can conduct electronic signals from the integrated circuit to the The printed circuit board where it is located. Under the BGA package, the pins are replaced by solder balls at the bottom of the package. These solder balls can be configured manually or through an automated machine, and they are positioned through flux.
BGA packages can provide more pins than other packages such as dual in-line packages or four-side flat packages. The ground surface of the entire device can be used as pins, which can be shorter than the surrounding package types The average wire length is to have more high-speed performance.
DIp dual in-line package
The so-called DIp dual in-line package refers to an integrated circuit chip that is packaged in a dual in-line form. Most small and medium-sized integrated circuit ICs use this package form, and the number of pins generally does not exceed 100. The CpU chip with DIp package has two rows of pins, which need to be inserted into the chip socket with DIp structure. DIp-packaged chips should be especially careful when plugging and unplugging from the chip socket to avoid damage to the pins.
