There are many reasons why laser drilling is superior to other procedures, such as plasma cutting.

Lasers are capable of providing unmatched levels of machining, particularly in micromachining applications.

Here are some of the simple and well-known benefits of using lasers as a drilling medium:The heat-affected zone is very small or negligible.

This leads to minimal distortion of parts.Since part distortion is minimal and the overall finish quality is superior to other drilling methods, the need for secondary finishing operations is drastically reduced.It is one of the most preferred drilling methods for intricate part machining.

This drilling technique is capable of providing narrow kerf widths.Highly advanced laser systems can be custom-built for specialized tasks.

Customization also ensures that these machines have very high repeatability.Since laser micro drilling is CNC controlled, close nesting of parts ensures minimal material wastage.

Picosecond lasers are best suited to machine materials that suffer from negative thermal effects during nanosecond laser machining with much higher performance. Nowadays, when it comes to material machining, the term "ultrafast lasers" is used more and more. Picosecond laser micromachining is becoming increasingly popular due to the outstanding superficial finish. This is accomplished due to lower heating and reduced debris-related effect. Not to mention the enhanced coupling due to the nonlinear intensity-dependent absorption and the obvious ease with which the machining effect can be achieved. But this only occurs with thin coatings of less than one-micron thickness.

The trend in designing printed circuit boards (PCB) towards smaller features at very high densities is necessary to serve the fast-growing demand for high-tech customer products.

This includes new laser processing capabilities, including laser micro drilling.

PCB drilling machines are a modern generation of drilling machines that use a high-power picosecond laser to allow the higher output of blind holes in PCBs.How It WorksThe PCB drilling machine uses a short lapse pulse with a high power density to quickly feed energy into the workpiece, causing the material to melt and vaporize.

The greater the pulse energy, the more material is melted and vaporized.

Vaporization will cause the material volume in the drilled hole to increase suddenly, creating high pressure.

This will cause the vapor pressure to expel the molten material from the hole.Percussion Drilling with Laser Micro drillingThe PCB drilling machine has to make through holes (vias), and blind holes have to be drilled into the printed circuit board, which acts as the interconnections between the layered systems.

The femtosecond laser micromachine is a crucial laser system developed for a specific industrial process.

Almost every surface laser system has been widely used in micro-processing with the ability to produce micro features with high accuracy and repeatability.

The increasing working distance problem for micromachining and molding is solved by the newer femtosecond laser machine range.

For mold manufacturers who have used the technology to create precision and accuracy beyond the capacity of traditional milling or EDM machines, lasers have become an invaluable tool.Femtosecond lasers emit very high peak pulse strength, which in effect induces non-linear multiphoton absorption in the material.

In more than two decades, after a team of researchers from the Center for Ultrafast Optical Science at Michigan University first demonstrated the use of a femtosecond laser for micromachining, this technique has taken the evolutionary transition from experimental hardware to reliability.Picosecond and femtosecond laser micromachining has developed into a reliable tool for precise manufacturing.

Electronic industries use it to drill and machine into hard metals.

Owing to its specific properties, such as non-contact manufacturing, no mechanical cutting forces, and no process tool wear, laser micromachining of transparent materials such as glass is an ideal method.

However, the use of traditional lasers to machine tungsten carbide, such as the nanosecond pulsed laser, has been found to induce thermal effects, issues with residual material redeposition, and other problems.Picosecond pulsed laser has evolved as an efficient micromachining process.

This technique can drill high-quality microholes, engrave various features, and produce micro or nano surface structures on a transparent surface.Laser micromachining of glass (transparent materials)The high clarity, strength, and chemical inertness of glass are the reasons why picosecond laser micromachining is commonly used in many consumer electronics.

Besides, future systems are expected to focus more heavily on the glass substrate to provide increased structural rigidity and introduce feature holes needed to be drilled into the glass.However, as glass substrates are thinner to accommodate smaller and lightweight products, conventional glass drilling methods fail to retain the necessary consistency.

It is crucial that edge cracking and residual edge tension are eliminated for touchscreens where panels nearly often break from the edge, even though stress is applied to the center.

This problem can be solved by the high peak power of picosecond lasers.Since glass is practically invisible to visible wavelengths, only infrared or ultraviolet wavelengths are used.

 High speeds and high versatility are the main benefits of laser micromachining when it comes to drilling and making holes.

Micro-drilling has two distinct laser processes as with cutting: fusion drilling with pulsed lasers and additional gas support - and vaporization-induced melt ejection, such as with q-switched solid-state lasers.

By choosing the proper wavelength and power density of the laser beam, almost all solid materials such as metals, semiconductors, plastics, ceramics, diamonds, etc.

can be laser-drilled.Various Methods for Laser DrillingFor selective roughening of surfaces for gluing and coating processes, pulse drilling of holes at a depth of some microns is used.

Single-pulse methods may be used for through holes in small workpiece thicknesses.For thicker materials, percussion drilling is the first option and can be accomplished by applying several laser pulses with the appropriate depth.

A combined drilling-cutting method or the multi-pass method is used for trepanning drilling for large diameters.Laser drilling of silicon wafers by Laserod creates virtually no micro cracks or edge melting that could weaken the cell during further processing.

Laser marking and laser engraving innovations in the pattern or mold making industry are becoming ever more prevalent.

Mold makers know that machining small cavities in molds are difficult and time-consuming, and extensive hand polishing is usually required to finish the job.

If the mold is either hardened or constructed of pre-hardened materials, the job is rendered much more difficult.

Deep laser engraving provides an effective form of machining without contact that is effective on hardened tool steels and can penetrate hard-to-reach areas.Deep Laser EngravingDeep laser engraving is generally regarded as a machining process that removes up to 30 thousandths of an inch of material.

It is often used for adding details to molds such as patterns and shapes, or for adding identification marks.Advantages of Laser EngravingA significant advantage of using picosecond and femtosecond lasers to engrave molds is that they operate well on hardened steel surfaces.

It also works wherever there is a line of sight to the point to be marked.

Femtosecond laser solutions, which include micromachining, are constantly growing and evolving across various business areas.

Ultrafast lasers are predominantly used in applications where the requisite HAZ and efficiency are not achieved by traditional CW, long-pulsed fiber, nanosecond, and picosecond laser systems.A femtosecond laser represents 10 to the −15 of a second, which is one-millionth of a billionth of a second.

At given pulse energy, the laser's peak power increases as the pulse's length become shorter.

Hence, femtosecond lasers have a much higher peak power than longer pulsed picoseconds, millisecond or nanosecond pulsed lasers.Since total energy is transmitted to the substance and less is drawn into heating the material, these higher peak powers result in higher removal rates in a material.

These femtosecond lasers' high peak power, sometimes several-MW, disrupts the atoms and electrons in the material, resulting in what is known as a "Coulomb explosion."

A Coulomb explosion is an-alternative cold processing to traditional thermal ablation used by longer pulsed lasers.Ablation is a thermal mechanism that relies on molecules and atoms local heating, melting, and vaporizing.
