PCB-Separation: Controlling ultrashort pulse laser using chromatic-confocal sensors (Depanelling Systems)

Neu-Isenburg (Germany), 5.9.2016

When chips are disassembled, a process known as depaneling, precision down
to the micrometer is required in both processing and positioning. The depanelling system, built by iC-automation,meets this challenge with a combination of confocal optical measuring sensors and and ultrashort pulse laser made by TRUMPF.

Optical Sensors conquer 3D Surface Measuring Machines

Neu-Isenburg (Germany), 4.7.2016

How does the 3D measurement of electronic components work? At first glance, the measuring machines used here look like their relatives from the mechanical world, the high-end coordinate measuring machines. Yet much is different and it starts with the name: We speak of 3D surface measurement systems for microelectronics or microsystems technology, for precision engineering or for the tool industry; and the all-rounders among these can offer several sensor systems. Optical sensors are taking over the lion’s share of the measuring tasks.

Up to four different measuring systems can be found on the sensor carriers of the cyberTECHNOLOGIES 3D surface measurement machines.

Application Story

[Translate to englisch:] CHRocodile C.

CHRocodile C – a new, non-contact and compact sensor system for distance and layer thickness measurements

The chromatic CHRocodile C sensor with its robust and integrated design the size of a cigarette pack offers high precision distance and thickness measurements.

CHRocodile C is specially suited for industrial inline use and easily integrable into any kind of inspection machine.

Thanks to its compact dimensions and excellent performance/price ratio, CHRocodile C is the ideal alternative to classical laser triangulation sensors.

Ultrashort-Puls Laser Depaneling of Assembled Circuit Boards

Depaneling circuit boards by means of stamping, mechanical sawing or milling there is a risk of traces of smoke covering the cutting surfaces. This is a sign of thermal stress and high temperatures. Sensitive components can thereby be harmed. Ultrashort-pulse laser systems are prove to be a good alternative. Highly accurate CHRocodile sensors are used to control the focusing of height of the laser for optimal depaneling using ultrashort laser pulses.

Contactless 3D measurement with latest multi-point sensors

Heye International’s Mark Ziegler and Gerd Schütz discuss the importance of wall thickness measurement in the high speed manufacture of lightweight glass containers and the use of Chrocodile chromatic confocal sensors from Precitec Optronik GmbH in Heye cold end inspection machines.

Medical Technology: Measuring Wall Thickness of Balloon Catheter

It is almost impossible for the wall thickness of balloons and thin-walled tubes (from which balloon catheters are manufactured) to be measured from the inside. The wall thicknesses can merely be estimated mechanically. But a simple solution exists in the form of optical noncontact measuring techniques which offer thickness measurements as a starting point, because these techniques offer so much more.

Fastest line sensors measuring tiniest structures

Semiconductor technology is celebrating a very special global jubilee: the law that is only valid for semiconductors turns 50 - Moore’s Law - it states that the complexity (sometimes also the level of integration) of integrated circuits doubles, depending on the source, every 18 to 24 months. In parallel and almost as impetuously as the digital revolution, which triggered this law, is the ongoing development of optical measurement techniques for semiconductors. Line sensors based on chromatic-confocal technology are nowadays state of the art. This report describes the technology and the results of this measurement technique for the smallest structures in the micrometer range.
