Why Laser Micro Drilling Is The Preferred Choice Of Every Industry

Industrialization has evolved over the years. Previously, the work used to be performed manually, then with tools, and with machines, and now with automation. Automation is a major step in the world of industrialization. The use of basic machines declined with the incoming automation, be it in the food, apparel, or manufacturing industries. Every major industry has undergone this enormous transition. 

The use of lasers has been the latest step in the world of industrialization. Laser micromachining involves the processing of substrates through electromagnetic radiation. A laser is a visible light that can be manipulated with the use of lenses. Various industries consider that laser cutting, laser micro-drilling, and other laser services have reduced human labor and have also improved their working method.

In laser cutting, the material is either made to melt, vaporize, or burn and the residue is made to blow away with a jet of gas. This is a method that brings high-quality furnishing to the surface of the metal. There is no stress of wearing and tearing of machines because it uses the computerized method in cutting the metals. The cutting of metals is done without any loss of material, and moreover, it is done with precision. The utilization of lasers makes it possible to machine some metals that prove challenging to cut or drill.

Laser micro-drilling is the process by which complex holes are drilled at very shallow angles without producing excessive heat. The laser ablation removes material from a solid surface by irradiating it with a laser beam. Laser converting is another process by which the manufacturers can produce a specific feature that is otherwise not possible. By that same token, laser engraving is another service in which lasers are used to etch something on objects and metallic surfaces.

What Are The Advantages Of Picosecond Laser Micromachining?

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. It is used to distinguish picosecond and femtosecond lasers for applications.

In picosecond lasers, the laser pulse length is shorter than the time required for absorbed laser energy to propagate to the substrate and is usually between 5 and 10 picoseconds (ps). 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. The picosecond laser micromachining will produce a minimal size. This delivers features slightly smaller than one micrometer in size. But this only occurs with thin coatings of less than one-micron thickness.

The standard value is 10 microns laser-cut size for deeper beam penetration. Picosecond laser micromachining is utilized for high-quality components to achieve the best performance. Picosecond lasers are capable of allowing machining techniques that do not depend on ablation. The picosecond laser can achieve results with outstanding sidewall profiles. This can be obtained in the scribing of sapphire wafers for the singulation of LED products.

If properly optimized, picosecond processing can yield results that are not possible with other techniques. Effective implementation needs knowledge and analysis of material-photon interactions, time-dependent process-rate changes, and sample handling if possible, gains are not affected by conflicting device specifications.

How High-Power UV - Femtosecond and Picosecond Lasers Assist In Precision Micromachining

The foundation of our industrialized society depends on technological advancement. For a manufacturer, producing a tangible product has often meant shaping, modifying, and joining different materials. That means creating more complex products, utilizing fewer resources, and becoming more cost-effective, year after year. Production processes have now had to switch from conventional machining to modern high-power UV laser micromachining.

Industries such as energy, transportation, and consumer electronics need better pricing for ever-increasing features. Medical devices benefit from improved miniaturization but must also meet rigorous limits on biocompatibility. Products for these industries need continued improvement in size and cost reduction while at the same time improving capabilities. Femtosecond and picosecond laser micromachining has, in large part, enabled this achievement, especially in markets with acute sensitivity to scale or constraints.

Advantages of high-powered UV lasers

For precision micromachining, UV lasers such as femtosecond and picosecond lasers have certain inherent benefits over their longer wavelength counterparts. To produce better quality outcomes, shorter wavelengths and shorter pulse widths are crucial. The optical propagation wavelength dependency ensures that the strength of a short wavelength beam can be concentrated on a smaller spot scale. For a larger distance (known as the depth of field), a beam can retain its minimum diameter.

This makes it possible for a drilled hole to have less taper or less target position sensitivity than for a longer wavelength beam concentrated at the same distance. Most surfaces heavily absorb UV, and hence the energy of the beam is absorbed within a shallow layer, aiding in the surface ejection of material.

The optical strength of pulses of a given temporal length is given by a standard industrial UV laser. Each pulse reacts strongly with the surface of the material, thereby causing the material to be removed with each pulse. Although only a small amount of material can be removed with each pulse, delivering these pulses at a high pulse repetition rate (PRF) allows accurately regulated features which can be easily produced.

The smaller attainable spot sizes make for smaller kerfs (cutting widths), greater consistency in smaller areas of redeposited material, and less total heat deposited into the workpiece. The adverse thermal effects impacting the surrounding material's (HAZ) properties are then reduced.

As for pulse widths, in the picosecond regime, ultrashort pulses generate extreme peak powers that result in nonlinear absorption in the substrates for instantaneous vaporization of material, with very limited deposition of heat into the material and negligible HAZ. This is generally referred to as a method of "cold ablation."

Process yield and throughput can be improved by high-power UV lasers such as femtosecond and picosecond laser micromachining. The significant throughput increases result from better processing efficiency & higher average power, resulting in lower overall laser machining costs.

Why Femtosecond Laser Micromachining Is A Preferred Choice Over Other Micromachining Methods

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. For some laser applications, ablation can be harmful. It usually creates unnecessary HAZ, recast, and burs, all of which have adverse heat effects that make cold ablation a better option.

All That You Wanted To Know About Laser Drilling

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 Drilling

For 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. Contacted solar cells on the rear side expand the solar-active surface and thereby cell output. Current through-plating technologies include the trepanning of some hundreds of holes with a diameter of up to 500 μm (MWT technology) or percussion drilling of many thousands of 65 μm (EWT technology) holes in each cell.

The EWT technology can achieve throughput levels of 4,000 holes/sec during this time-critical processing stage and the MWT system can achieve up to 100 holes/sec.

Choose Laserod Technologies For Laser Engraving Mold Cavities

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 Engraving

Deep 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 Engraving

A 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. Laser engraving gives a better finish to the surface that usually requires no hand polish. It has a lower impact on molds' surface strength and eliminates the possibility of micro-fracturing that exists with EDM.

Everything You Wanted To Know About Cold Ablation

The ablation method is fundamental for laser micromachining. Conventional pulsed-laser machining processes dissociate matter at atomic and molecular levels by application of laser radiation. The absorbed laser energy is passed to the material's atomic and molecular lattice, which induces ablatement of the substance. Simultaneously, this energy is ultimately transformed into heat that disperses out of the laser spot volume beyond the laser pulse duration.

However, surgically clean and extremely localized laser ablation is possible without significant damage or alteration of the underlying material, by using femtosecond laser micromachining.  Femtoseconds are the time-scale in which a process called cold ablation can develop.

The principle of cold ablation is an ablation that happens in the process of femtosecond laser absorption, during the athermal state of the substance. The aim is to remove excess material before it is in a state of total thermal equilibrium, allowing it less chance to create heat that will migrate away from where directly absorbed laser energy.

The material's athermal ablation and thermalization happen simultaneously, unlike digitally turning it on or off in the time. This makes the time for the cold, athermal, or thermal ablation largely overlap each other at various degrees of weights. Moreover, heat build-up and dispersion can happen in parallel, which moves the heat out of the laser-spot volume by the electron subsystem and atomic or molecule lattice methods.

Fast repetitive laser pulses are utilized to ablate material to increase the ablation rate, which adds further difficulties in almost all practical cases. This often reaches a significantly elevated temperature in the material. The temperature is, however, not necessarily high enough for ablation, but it can melt down the solid-state material. So perfect material ablation demands modern femtosecond laser micromachining systems, applications, and expertise.

Superior Laser Micromachining Of Thin Metals With Laserod Technologies

The laser micromachining of small parts accurately and repeatability on thinner sheet metals requires a precise system. Otherwise, you're just using a sledgehammer to crack nuts and losing money in the process. The use of a high-power laser on thin metals will cause all sorts of problems that could be prevented by a less powered machine. A high-power laser, for example, is required to cut thick metal, not thin ones, so it can become unstable by under performing it.

The running costs involved are not comparable with a low-powered system, either. Set-up costs can also be out of proportion to the work's value. In some cases, using a high-power laser to cut small parts can double the production costs.

At Laserod, we have developed a small part laser micromachining solution for different types of metals. Our thin metal cutting and drilling system is a laser cutter optimized for micromachining small parts in both prototypes as well as industrial environments.

Operating on various metals, from steel to titanium, alloys to aluminum, our femtosecond and picosecond laser micromachining systems provide superior performance and unmatched reliability.

A lot of laser micromachining firms have trouble cutting and drilling thin metals, but Laserod doesn't. The cutting and molding of thin metals are one of our many specialties and our use of femtosecond and picosecond laser micromachining systems guarantees low thermal distortion. Our range of laser-cut widths (kerfs) is 10-50 microns.
