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

Neu-Isenburg, 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 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

Ultrashort-Puls Laser Depaneling of Assembled Circuit Board

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.

Nuova flessibilita nel tagliio laser

Il nuovo “ProCutter” compatto è stato sviluppato appositamente per il taglio laser per fusione di materiali con spessore sottile e medio nell’area della lunghezza d’onda intorno a 1 μm. Questo nuovo sviluppo offer la massima flessibilità grazie a una tecnologia dei sensori integrata, tre varianti di esecuzione e la possibilità di configurazioni personalizzate. «Al giorno d’oggi, chiunque utilizzi macchine di taglio laser, avrà bisogno di teste di taglio che uniscano una struttura leggera e compatta alla flessibilità e a una tecnologia dei sensori intelligente. Sono esattamente questi gli obiettivi che Precitec realizza con la famiglia di prodotti ProCutter. L’interesse mostrato alla EuroBLECH di quest’anno è stato dunque notevole. Infatti, grazie alla propria flessibilità, ProCutter si adatta perfettamente ai diversi requisiti del processo, del laser e della macchina », ha dichiarato Alexander Gatej, responsabile di prodotto presso Precitec nella sede principale a Gaggenau.

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.
