Measuring Brake Rotor Thickness Variation with Capacitive Sensing
Brake rotor thickness variation, or disc thickness variation (DTV), causes uneven wear to brake rotors, disc-shaped automotive parts that are squeezed between brake pads to slow or stop a vehicle’s wheels. When a brake rotor has areas of different thickness, the amount of clamping force that’s applied across the rotor’s surface varies. These differences in clamping force lead to difference in torque, and the results may include brake shuddering, pulsating, or vibration. Even under normal driving conditions, brake rotors are subjected to extreme conditions that can cause performance-related issues. To ensure that brake rotors can perform properly without problems such [...]

Proforma 300i SA Video Shows Semiconductor Metrology
MTI Instruments, a worldwide leader in precision measurement solutions, has released a YouTube video that shows how its Proforma™ 300i SA semi-automated measurement tool measures silicon carbide wafers for semiconductors. George Relan, MTI’s Global Director of Sales, demonstrates how the desktop metrology system provides non-contact full wafer scanning and 3D mapping of measurement features such as thickness and shape. MTI’s video also shows how the Proforma 300i SA interfaces with an external computer and provides powerful Windows-based software for analysis and reporting. By utilizing MTI push/pull technology, the Proforma 300i SA doesn’t require the semiconductor wafers to have a [...]

3D Integrated Circuits Use Capacitive Sensing to Ensure Coplanarity
Three-dimensional (3D) integrated circuits (ICs) feature silicon wafers and dies that are stacked vertically for improved device performance. By using the Z-axis, 3D ICs can overcome the power and footprint limitations associated with two-dimensional (2D) integrated circuits. Yet 3D ICs need coplanar surfaces to contact all of the pads, pins, and pillars. To determine coplanarity, semiconductor manufacturers measure the angle and gap between two planes. Bonding tool actuators use these measurements to adjust components and ensure that all device pins and solder balls reside on the same geometric plane. This process, active parallelism compensation, promotes proper bonding without residual [...]

Selecting a Displacement Sensor / Measuring System
Capacitive displacement sensors Capacitive displacement sensors are non-contact devices that are used for measurements at a high-resolution. It can also be used to check the position of any conductive object as well as measure the width or density of non-conductive materials. Capacitive displacement sensors have a large variety of uses including precision thickness measurements, assembly line testing, assembly metrology, and semiconductor processing. Capacitive displacement sensors can be found in manufacturing facilities all around the globe. There’s more to selecting the proper type of displacement sensor and measurement system than meets the eye. To select the appropriate type of device [...]
Target Material and Characteristics
Target Material and Characteristics Transparent/Opaque Targets There are a number of measurement systems that are capable of measuring a target that is opaque. When it comes to transparent targets, the measurement system being used must match the material of the target being measured. For example, if you’re attempting to measure plastic you should use a contact-type measurement system such as a micrometer. When performing a soft target measurement, such as film, a non-contact measurement system (such as a laser displacement sensor) should be utilized. Hard/Soft Targets Objects made out of hard material (such as a block of wood), would [...]
