Kelvin Spring Probes test sockets bur-in socket Aries Larsen Associates

Kelvin Spring Probes: A Kelvin contact can be made using either two standard spring probes with pointed tips, shown below, or with the dual Kelvin probes with slanted tips shown above depending upon the pad space avaialble and pitch requirements. With Aries Kelvin spring probes an amazing 0.10 mm tip spaceing can be achieved. Send us your requirements for an estimate or price and delivery quote.

KELVIN Testimonial:

".......Just wanted to give you an update on how the Aries Kelvin sockets performed.The socket for our device performed excellent both electrically and mechanically.Tested over 10k parts on the SRM handler with the Aries socket. The tips were very well centered on the pads. Later we will be testing more sockets and I expect them to perform just as well. I am very satisfied with the price and performance of Aries sockets. I would have no reservations about recommending Aries sockets to my colleagues........"

Now available 0.1 mm tip spacing
1GHZ or less = DATA SHEET # 23022.pdf
FEATURES
- Low resistance testing using dual independent Aries Kelvin spring probe technology per device pad for testing of MLF, QFN, LGA and other leadless devices.
- Any pitch device on 0.40mm pitch or higher
- Socket is easily mounted and removed to & from the test board due to solderless pressure mount compression spring probes which, are accurately located by two molded plastic alignment pins and mounted with four stainless steel screws
- The Au over Ni plated compression spring probes leave very small witness marks on the bottom surface of the device pads
- Small overall socket size/profile allows max. number of sockets per test board, while being operator friendly
- Kelvin Test Socket Contact System is available for any Aries CSP and Center Probe Test Sockets
- Pressure pad compression spring provides proper force against device and allows for height variations in device thickness
- Probe blade edge tip for cutting through solder oxide layers
- Signal path during test only 0.082 [2.08]
