What is a Pin Grid Array (PGA)?

What does PGA stand for?

A pin grid Array (PGA) is the incorporated Circuit packaging standard used in most 2d- through fifth-era Processors. Pin grid array Packages have been either rectangular or rectangular in Form, with pins arRanged in a regular array. Pin grid array become favored for processors with larger-width Data Buses than dual in-line pins, as it can handle the desired quantity of connections better.

What Does Pin Grid Array Mean?

The pin grid array commenced with the Intel 80286 Microprocessor. It turned into hooked up on a Printed Circuit Board either via Insertion into a Socket or once in a while via the via-hole technique. Pin grid arrays had many variations, such as:

• Ceramic — PGA in ceramic packaging
• Flip-Chip — Die going through downwards on top of the substrate
• Plastic — PGA in plastic packaging
• Staggered — Pin layout staggered for tight compression
• Organic — Die connected to an natural plate

One of the largest advantages supplied via the PGA is the number of pins available in step with incorporated circuit in comparison to older packaging requirements just like the dual in-line programs. This served properly for more recent processors with wider Data and cope with Buses. Moreover, PGA is cHeaper than the Ball Grid Array and other grid arrays.

However, the pin connections of the PGA are regularly less dependable and the PGA era additionally had sure limitations on thermal and electric skills. These drawbacks Finally resulted inside the PGA being step by step replaced with the aid of different standards which includes the ball grid array.
