PCB-Separation: Controlling ultrashort pulse laser using chromatic-confocal sensors

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 an ultrashort pulse laser made by TRUMPF.

3D Surface Measuring Machine (Profilometer)

3D Surface Measuring Machines (Profilometer)

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

CHRocodile C.

CHRocodile C – Un nouveau capteur sans contact ultra-compact pour la mesure de distance et d’épaisseur

Le capteur chromatique CHRocodile C avec son design robuste tout intégré de la taille d'un paquet de cigarette offre des mesures de distance et d'épaisseur de très haute précision.

Le CHRocodile C est spécialement dédié pour l'utilisation industrielle en ligne ou une intégration dans les machines d'inspection.

Grâce à sa dimension compacte et son excellent rapport qualité/prix, le CHRocodile C est une alternative idéale au capteur à triangulation laser

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.

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.

Wall thickness measurement for non-round ware

Heidi Olson describes an optical probe, designed by Precitec Optronik for the wall thickness measurement of non-round containers. Using a specialized optical design, the probe enables measurement at angles more than double that possible with other techniques. This is advantageous for both rotating measurement of non-rounds, as well wall thickness determination on highly decorated containers.
