Used PREMTEK 9920 #9257410 for sale

PREMTEK 9920 is a fully automated wafer prober that can be used to analyze and inspect complex integrated circuits with accuracy and versatility. This prober consists of three main components: a probe head, a microscope, and an XY stage. The probe head is equipped with several test needles that can be programmed to accurately contact the test points on the wafer in order to measure electrical signals with repeatable accuracy. This signal is then transferred through the microscope to the XY stage, which moves and positions the wafer that is being tested. The probe head is one of the most critical elements of PREMTEK wafer prober. It consists of several components, including a base plate, a controller, and test needles. The controller with the base plate allows users to accurately program the needles. This programmed pattern enables the needle to contact the test points on the wafer. The needles are made with a special material that is highly durable and does not damage the wafer during the inspection process. The design of the base plate and needles also ensure signal connection is maintained during XY stage motion without any wobbling. In addition, the microscope is designed to allow precision imaging of the wafer while it is in contact with the probe head. This microscope is integrated with a CCD camera and image processing software which can be used to perform a variety of analysis on the wafer and detect any defects in the semiconductor patterns. The XY stage moves and positions the wafer at the locations that have been programmed into the prober. This stage is equipped with a closed-loop control system that monitors the position of the wafer and prevents out-of-tolerance wafer movement. It also allows the wafer to be finely adjusted to make sure it remains within its programmed boundaries while being tested. 9920 prober is capable of testing a variety of integrated circuits and is ideal for high-volume applications. Its components are highly precise, durable, and dependable, providing users with excellent performance and reliability. Its user-friendly interface also makes it an ideal choice for both novice and expert users.
