Probe cards are broadly classified into needle type, vertical type, and MEMS (Micro Electro-Mechanical System) [4] type depending on shape and forms of contact elements. MEMS type is the most advanced technology currently available. The most advanced type of probe card currently can test an entire 12" wafer with one touchdown.
The wafer prober brings an array of microscopic needles or probes called a probe card into electrical contact with the wafer (vacuum-mounted on a wafer chuck). WPT and WFT use different probe cards, the WFT card contacts a chip's bond pads. After each test the prober moves the wafer to the next testing location.
Technoprobe was founded in Merate near Milan in 1996 by Giuseppe Crippa, who had developed a new and more rapid method to manufacture probe cards. [2] As the company grew, it opened manufacturing and sales offices abroad, including in Rousset, France (2001), Singapore (2003), San Jose, California (2007), Philippines (2010), Korea (2015), and Japan (2018).
FormFactor (FORM) announces the opening of a new probe card manufacturing facility in Livermore, CA, in a bid to bolster its presence in the United States.
Using mechanical probes has certain drawbacks: mechanical probing can damage the circuits under the probe pad on the IC [1] repeated probing can damage the probe pad on the IC, making further probing of that IC impossible; the probe card may be damaged from repeated contact, or become contaminated with debris created by contact with the wafer [2]
The electron microprobe (electron probe microanalyzer) developed from two technologies: electron microscopy — using a focused high energy electron beam to impact a target material, and X-ray spectroscopy — identification of the photons scattered from the electron beam impact, with the energy/wavelength of the photons characteristic of the atoms excited by the incident electrons.

LXI-compliant instruments offer the size and integration advantages of modular instruments without the cost and form factor constraints of card-cage architectures. Through the use of Ethernet communications, the LXI Standard allows for flexible packaging, high-speed I/O, and standardized use of LAN connectivity in a broad range of commercial ...
