I) Introduction

This technical specification is an outline of the machining capabilities of Applied Laser Solutions Ltd; i.e. the laser machining, drilling and scribing of thick and thin film Alumina. This specification is intended for engineers and quality personnel, to help them understand and design substrates for laser processing.

If your requirements fall outside this specification, then please contact Applied Laser Solutions Ltd. It is possible that your criteria could still be met.

II) Laser tolerances

a) Laser scribing (see Fig. 1)

1) Scribed pulse depth: 35 - 50% standard across all thicknesses

2) Pulse spacing: 0.14 - 0.17mm between each laser pulse

3) Scribed edge to feature: +. 1/-.05mm

4) Scribe line to scribe line: +/-.05mm

b) Laser drilling and machining

The tolerances specified below are standard tolerances, however tighter tolerances can be achieved, please contact Applied Laser Solutions Ltd if your criteria are not met within these specifications.

Length and Width +/-.002" (+/-.051mm)
Hole and Feature Location +/-.002" (+/-.051mm) From any machined area to hole centreline +/-.002" (+/-.051mm) From centre of scribeline to hole centreline
Hole Diameter +/-.0015" (+/-.0381mm)
Medium Hole Diameter Single shot .003" (.06mm) Drilled .004" (.1 mm)
Medium Web Thickness hole edge to another edge substrate thickness between adjacent holes substrate thickness
Narrowest Profiled Slot .004" (.102mm)
Corner Radii minimum .006" (.15 mm) Nb. To reduce the risk of microcracking and chipping it is recommended that an internal radii is used in preference to a sharp corner

c) Special requirements

The above tolerances are standard, however if you have a special requirement such as post definition work (i.e. pre-printed tiles) or work from a pre-machined/snapped edge then please contact us for more details. We will endeavour to meet your criteria or we can advise upon the achievable tolerances.
