Probe cards

A probe card is an interface between an electronic test system and a semiconductor wafer. Typically the probe card is mechanically docked to a prober and electrically connected to a tester. Its purpose is to provide an electrical path between the test system and the circuits on the wafer, thereby permitting the testing and validation of the circuits at the wafer level, usually before they are.

Based on improved “Buckling Beam” technology – Cobra , the cards are adapted for bond pad patterns such as full array,semi-array,peripheral and staggered – chip pattern. Production RF probe cards are rugge robust, and well suited for the rigors of high-performance wafer sort.

Their industry-leading signal integrity and mechanical capabilities make these probe cards the perfect fit for multi-die testing for RF wireless and high-speed digital in SiPs and SoCs. In this tutorial, the discussion will be limited to epoxy and blade probe cards because they are the types most commonly used for parametric test. It is used to connect to the integrated circuits located on a wafer to the ATE (Automated Test Equipment) in order to test their electrical parameters and performance before they are manufactured and shipped out. Integrated circuits are built from roun thin sheets of semiconducting material.

Standard sheets, or wafers, are commonly made of silicon. What is a probe card? The probe cards typically provide 4 7 1or 1pin edge connectors.

Rectangular or round cutouts can be routed in the card to suit the device and thin or thick stiffeners are applied to provide additional card rigidity and extend the operational life of the card.

CANTILEVER PROBE CARDS. With specialist probe card facilities based in Europe and North America, we build a wide range of standard and custom cantilever probe cards based on epoxy and blade technologies. Our epoxy probe cards can accommodate high pin counts and benefit from competitive pricing and quick turn-around times.

The hybrid probe card combines electrical and optical tests in one solution. This allows multiple optical and electrical channels of a PIC or even several PICs to be tested in parallel, regardless of their arrangement, thus meeting the demand of opto-electronic tests for high-volume applications. Alpha Probes is headquartered in the shadows of the Colorado Rocky Mountains, Colorado Springs, where all our engineers come with at least years of experience within their field. No job is to small. All our probe cards are made here in America using American parts.

Probe Cards , Probe , Semiconductor. CAGR of with advanced probe card segment having largest market share. Miniaturization of electronic products will also fuel probe card market industry growth.

In cases where the card is not meeting performance specification, repairs may be performed such as tip adjustment or card cleaning, thus returning the card quickly to a production state.

The cable connections to the probe card are usually edge finger (up to pins) or ribbon cable (up to 1pins). Translarity offers probe card solutions for the global semiconductor and packaging test industries, tailored to customer specifications. The company’s IP portfolio, design capabilities, innovative products, and reputation for quality, reliability and customer support ensure the right solution for your testing requirements. It is reminiscent of the simple two-person game Hangman, whose object is to guess a word chosen by another player by revealing specific letters. Asia Pacific is the major region in the global probe cards market , and have many probe cards manufacturers, such as United Microelectronics, and Taiwan Semiconductor Manufacturing.

DTS probe card blanks are made to precise specifications required for all probing technologies and are available in high speed and high temperature materials. Semi- Probes , Incorporated: Semi- Probes , Inc. Continuous miniaturization of semiconductor devices in the forecast years is expected to present huge potential for the probe cards market manufacturers. All probe card PCBs employ a balanced layering construction to maintain tight flatness specifications and minimize warping, allowing good probe planarity.

Gold plating on all surface metals facilitates easy soldering and minimizes probe resistance. DTS is continually adding new probe card blanks to its library! They play a vital role in the final production process of semiconductor wafers.
