intelliDRILLse II

intelliDRILLse II is specifically designed for tasks, where fast positioning and

reliable beam control are essential – particularly for microdrilling.

The compact design allows for easy integration. Its lightweight beryllium

mirrors and digital encoder technology enable fast and accurate beam

positioning across varying jump distances. The system supports throughput

-oriented production environments. Optional SCANahead technology enables

predictive motion control of galvanometer axes and stage axes.

Highlights

• Fast step response times permit highest throughput

• New motor design with improved thermal management

• Lightweight beryllium mirrors – for reduced inertia and highest dynamic

performance

• Digital dynAXISse encoder technology-for accurate beam positioning

• Automatic jump time setting for all jump lengths and time-efficient parallel

handling of positioning and laser delays

• Synchronous motion of scan system and positioning stages is supported

through SCANahead technology

(SCANahead is optionally available for intelliDRILLse II, it is available as

standard for excelliDRILL.)

Enabling high-precision CO2 laser drilling for advanced PCB processing:

SCANLAB’s intelliDRILLse II and the new excelliDRILL are specialized

scan systems designed for demanding microdrilling tasks such as high

density interconnects (HDI).

Modern printed circuit boards require an ever-increasing number of

vertical interconnects, also known as vias. The density of these

interconnects continues to increase, while their size decreases.

Precision is of central importance for the functional implementation of

such designs. At the same time, manufacturing methods must offer very

high throughput.

Technology Overview

Laser drilling is an ideal process for the application, as it allows a very large

number of fine holes to be produced with a very high degree of precision.

For CO2 drilling processes, the laser spot has to be moved to a designated

position and it has to be settled precisely within tolerance, whereafter the

laser is triggered. A key requirement for this is a suitable scan system that

is capable of performing this “jump and shoot” process with maximum

efficiency. intelliDRILLse II and excelliDRILL are developed to meet the

specific requirements of high-precision microdrilling tasks.

High-End Laser Processing

The schematic diagram depicts XL SCAN’ssystem configuration.

This scan solution combines SCANLAB’s proven scan head

control with an XY stage positioned via ACS’s innovative motion

control system.

The laser spot’s movement across the workpiece is automatically

split between the scan head and XY stage, thus assuring optimal

utilization of the entire system’s available dynamics. The scan head

is responsible for short rapid motions, while the stage extends the

working surface.

Unbeatable precision meets large-field laser processing

XL SCAN is a combined scan solution jointly-developed by  SCANLAB

and ACS Motion Control. This innovative solution enables maximum-

precision processing of workpieces without size limitations.

Key Features

• Scan solution for large-field processing

• High throughput

• Market-leading accuracy

• No stitching errors

• High-dynamics processing without stage vibration

• Unlimited job duration

• Automatic laser control, e.g. Spot Distance Control (SDC)

• Capability of combining multiple software instances, stages

and scan heads

XL SCAN is based on the innovative concept of the SCANmotion

Control software, which combines the synchronous control of

a scan head and an XY-table with intelligent trajectory planning.

XL SCAN thus  delivers the highest precision of all solutions

currently on the market. Maximum flexibility and enormous

throughput increases are  attainable by combining XL SCAN

with several  SCANmotionControl instances, multiple stages

or multi-head systems.

Automatic Fine Adjustment

precSYS‘s factory-precalibrated beamposition measurement unit can be used

for monitoring the system’s beam position. If the beam position exceeds the

application specific tolerance limit, then the software can be used to readjust

the beam back to its original zero position by the system internal five galvo axes.

Advantages:

•  Beam position stabilization close to the working field minimizes deviations

along the beam path from laser to workpiece

•  Lastingly reproducible process results without complicated effect analysis

and manual readjustment

•  Beam position monitoring via maintenance software program

•  Automatic readjustment of beam position and angle via the DrillControl

software  (regulation via system-internal galvo axes)

•  Supports precSYS alignment during commissioning and servicing

Principle of Operation

precSYS lets you 3D-position the focalspot onto workpieces with

precise tracking of angles of incidence (AOI). You can simultaneously

vary progression of focal motion, angles of incidence and laser intensities

etc. High-end scan technology with small mirror rotation angles and

low moving masses ensure highly dynamic processing with trepanning

or precession frequencies up to 650 Hz (39 000 rpm). The system

works without any rotary optics.

Advanced digital encoders, control algorithms and application-optimized

servo control enable contour-true, speed independent processing with

maximum precision. The system is servo-regulated for stable positioning

at precession frequencies up to 650 Hz. Specially conceived for USP

precision processing, the opticalpath is polarization-maintaining and

accommodates pulse energies up to 300 µJ at 1030 nm and 65 µJ at

515 nm.

System Design

Active water cooling of beam-guidance components (including galvo axes)

and of spatially separated electronics makes the system robust against

load-dependent temperature fluctuations. Moreover, the system’s innovative

beam guidance provides suitability for up to 50 W lasers.

A sealed, gas-purged optical beam path(overpressure) guarantees optimum

cleanliness even in harsh industrial conditions – thereby enhancing system

service life and processing accuracy.

Key advantages:

•  User-friendly creation of micro-processing operations with 3D

visualization

•  Flexible USP processing with defined variable angle of incidence

•  Maximum dependability and stability for highest precision

•  515 nm variant for even more precise laser processing

control algorithms
