General Specifications


	Package Type
	Your choices are...
	BGA		Ball-grid array (BGA) places output pins in a solder ball matrix. Generally, BGA traces are fabricated on laminated (BT-based) substrates or polyimide-based films. Therefore, the entire area of substrates or films can be used to route the interconnection. BGA has another advantage of lower ground or power inductance by assigning ground or power nets via a shorter current path to PCB. Thermally enhanced mechanisms (heat sink, thermal balls, etc.) can be applied to BGA to reduce the thermal resistance. The sophisticated capabilities make BGA the desirable package to implement electrical and thermal enhancement in response to the need for high power and high speed ICs.
	CSP		Chip scale package or chip size package (CSP) has an area that is no more than 20% larger than the built-in die. CSP is compact for second level packaging efficiency and encapsulated for second level reliability. CSP is superior to both direct-chip-attach (DCA) and chip-on-board (COB) technologies. CSP is used in a variety of integrated circuits (IC), including radio frequency ICs (RFIC), memory ICs, and communication ICs.
	DIP		Dual in-line package (DIP) is a type of DRAM component packaging. DIPs can be installed either in sockets or permanently soldered into holes extending into the surface of the printed circuit board.
	SIP		Single in-line package (SIP).
	DIMM / SO-DIMM		Dual in-line memory module (DIMM) is a small circuit board that holds random-access memory (RAM) chips and is capable of transferring 64 bits. Small outline dual in-line memory modules (SO-DIMMs) are smaller and thinner than standard DIMMs.
	SIMM		Single in-line memory module (SIMM) is a small circuit board that holds random-access memory (RAM) chips and is capable of transferring 32 bits.
	LGA		Land-grid array (LGA).
	PGA		Pin grid array (PGA) is a second generation package that uses through-hole technology (THT). Pins are located on a 0.1" grid in various patterns. Package size is reduced by moving pins to the underside of the package in a grid pattern.
	IPGA		Interstitial package grid array (IPGA) carries additional pins on a 0.5" offset pattern in between the pins of a regular PGA pattern. It almost doubles the available pins on the same package size as a standard PGA.
	QFN		Quad flat non-leaded package (QFN). Also known as QFNL.
	QFP		Quad flat packages (QFP) contain a large number of fine, flexible, gull wing shaped leads. Lead width can be as small as 0.16 mm. Lead pitch is 0.4 mm. QFPs provide good second-level reliability and are used in processors, controllers, ASICs, DSPs, gate arrays, logic, memory ICs, PC chipsets, and other applications.
	PLCC		Plastic leaded chip carrier (PLCC).
	SOIC / SOP		Small outline integrated circuit (SOIC).
	TO		Transistor outline (TO) sockets are designed to accept transistors. There are many variations. For example, TO-3 has three pins, TO-5 has 5 pins, etc.
	TSSOP		Thin shrink small outline L-leaded package (TSSOP).
	VSSOP		Very thin shrink small outline package (VSSOP).
	Receptacle		Sockets are mounting board receptacles.
	Display Socket		Sockets are used for installing LEDs, incandescent lamps, switches, and other display devices.
	ZIP / SZIP		Shrink zigzag in-line package (SZIP).
	Test / Prototyping Socket		Sockets are used for testing or prototyping purposes.
	Other		Other unlisted or proprietary socket types.

	Mounting
	Your choices are...
	SMT		Surface Mount Technology (SMT) sockets are soldered to the PC board traces. Unlike PC mount sockets, surface mount sockets do not require holes drilled in the PC board.
	Through-hole		In Through Hole Technology (THT), components are mounted on printed circuit boards by inserting component leads through holes in the board and then soldering.
	Press-fit		With press-fit technology the pins of the connectors are not soldered into the PCB (thus avoiding heat stress) but rather are 'pushed (pressed)' into the PCB.
	Swage		Swaging is a forming technique in which the metal is deformed into its final shape by high pressure.
	Solder		The pins or receptacles are soldered to the pc board.
	Other		Other unlisted socket style.
