Scanlab excelliDRILL and intelliDRILLse II

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.

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.)

excelliDRILL

excelliDRILL is SCANLAB’s latest product development for drilling printed

circuit boards. The new motor design, SCANahead based control algorithms,

together with proven SE encoder technology, and lightweight beryllium mirrors

enable outstanding drilling rates with maximum precision. Compared to

intelliDRILLse II maximum jump rates are increased by more than 15% for

jump distances of 1 mm and more than 40% for jump distances of 0.2 mm

at a focal length of 100mm. Please refer to SCANLAB sales for prototypes of

excelliDRILL. intelliDRILLse II and excelliDRILL provide identical mechanical

and optical interfaces, ensuring compatibility with existing machine designs.

Typical Applications

intelliDRILLse II and excelliDRILL are optimized for a wide range of laser

microdrilling tasks in electronics manufacturing. These include:

• HDI PCB production – enabling precise via structures in high-density

interconnect boards, such as Any-Layer HDI

• Via hole drilling (VHD) – for multilayer interconnects

• Percussion drilling – for high-speed, high-volume hole creation

• Microvia creation – for fine-featured circuit designs
