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.

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 device.

Application Story

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.

[Translate to chinesisch:] Die schnellsten Liniensensoren messen kleinste Strukturen

[Translate to chinesisch:] Weltweit feiern alle Halbleiterchips dieses Jahr ein Jubiläum der besonderen Art: ein Gesetz, das nur für sie gilt, wird 50. Die Rede ist vom Mooreschen Gesetz welches besagt, dass sich die Komplexität (manchmal auch Integrationsdichte) integrierter Schaltkreise alle zwei Jahre regelmäßig verdoppelt. Parallel und fast genauso ungestüm entwickelte sich auch die optische Messtechnik auf der Basis chromatisch-konfokaler Technologien. Dieser Bericht beschreibt Technologie und Ergebnisse der Messtechnik für kleinste Strukturen im Mikrometerbereich.

Laser surface modifications at Tata Steel

In the manufacture of steel strip work, components have to perform in exceptionally aggressive environments and withstand service at high temperatures in corrosive atmospheres under mechanical wear and frequent and heavy impact loading. Conventionally, components that are subject to high wear or corrosion have often been manufactured from rich chemistry steels or hardfaced using submerged arc clad martensitic stainless steels (MSSs) to increase their service life and therefore maximize line throughput by extending maintenance intervals without any sacrifice to product quality.
