Lasers can cut many types of ceramic materials
Apr 25 , 2021
Lasers can cut many types of ceramic materials. The most common is alumina silicate (Al2SiO5), which requires either full ablation or the scribe-and-break technique. Each has its own advantages depending on your application’s requirements. Unlike other methods, ceramic laser cutting achieves precise heat control to cut detailed patterns. Other advantages include: No contact. Un...

How to Engrave on Plastic by 355nm laser
Apr 23 , 2021
How to Engrave on Plastic by 355nm laser Methods of laser marking on plastics Foaming Foaming leaves a tangible mark on the material. It can be seen as laser-induced boiling, which melts the surface. Due to the rapid cooling, bubbles are encapsulated in the material. These bubbles leave a positive mark, which is tangible. The laser works on a low power level and longer pulses. Foaming works on all...

Laser drilling of micro-holes in single crystal silicon, indium phosphide and indium antimonide using a continuous wave (CW) 1070 nm fibre laser
Apr 19 , 2021
The laser micro-drilling of “thru” holes, also known as via holes, in Si, InP and InSb semiconductor wafers was studied using millisecond pulse lengths from an IPG Laser Model YLR-2000 CW multimode 2 kW Ytterbium Fibre Laser and a JK400 (400 W) fibre laser, both with 1070 nm wavelength. The flexibility of this laser wavelength and simple pulsing scheme were demonstrated for semiconduct...

Method for testing for blind hole formed in wafer layer
Apr 19 , 2021
A new method for detecting blind holes in the contact layer of a multi-chip semiconductor test wafer makes use of the fact that if the hole is not a blind hole, a subsequent etch step extends the hole a predetermined distance into the layer immediately underlying the contact layer. After a predetermined number of holes have been etched through the contact layer and for a predetermined distance int...
