*Chip Scale Test & Burn-In Sockets Test & Burn-In of Any SMT Device!* CSP BGA LGA QFN DSP SRAM DRAM Flash Devices, etc.**
	4 point crown style tips are used for BGA ball or bump devices, wheras sharp tip pins are used for devices with flat contacts such as LGA, PQFP, SOIC, QFN, etc. PC board wear is virtually zero as springs are designed always compressed to the board. The springs are reliable to >500,000 cycles. Snap in, field replaceable, fully loaded, Interposers are available as spares.

	CSP Spring Probe Family: for any pitch .2 mm and up for surface mount device, any SMT footprint, standard or staggered or mixed pitch, or any configuration. Roll Over Thumbnails, View Larger Image.

	Typical Crown Tip & Pointed Tip Spring Probes, showing each, Left to Right, uncompressed not mounted, mounted on a PC board and compressed, mounted on a PC board with device in the socket.
	Typical Aries CSP Socket, (23018 style) showing crown tip probes for BGA contact inside of the socket, and compression springs on bottom to contact PCB pads.
	Kelvin Spring Probes. A Kelvin contact can be made using either two standard spring probes with pointed tips, or with the dual Kelvin probes with slanted tips shown.
Aries Spring Probes	Avaiable From 0.3 mm Pitch and Up. See Gallery 5A Interposer+Spring Probes
