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 Works

The 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 drilling

The 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. Both the holes should have straight walls. Percussion drilling using UV lasers is a method of choice for most PCB drilling. They reach very high drilling rates of several thousand holes per second and can drill diameters as small as 75μm.

The use of laser micro drilling makes it possible to drill smaller diameters. The creation of blind holes is easily achieved by controlling the number of pulses. Ramping up the pulse energy isnot required. The modern laser drilling machines are built in an external modulator. This is used to control and adjust the pulse energy, which varies from pulse to pulse, allowing precise control of the drilling process.

Laser micromachining involves laser micro drilling, laser welding, laser cutting, and laser system integration. It is the most efficient manufacturing technology and is rapidly gaining popularity. In any industry, whether military, medical, aerospace engineering, automotive, space propulsion, or high-tech manufacturing, laser micromachining has immense benefits.

It is the best solution for organizational and manufacturing needs as precision laser micro drilling leads to precision and perfection. Laser microdrilling is used in delicate operations as well as in processing industrial projects. Such is the diverse nature and benefit of laser microdrilling. Laser microdrilling is the most modern technique of drilling, and it leads to no distortion of material. Laser microdrilling is an excellent method for drilling any kind of material.

Laser microdrilling is always preferred over conventional drilling as it has a small HAZ (heat-affected zone). Micro-level holes, deep penetration with excellent precision, consistency with minimal distortion due to heating, no secondary processing, faster drilling rates, and high repeatability are the key advantages.

The benefits of laser microdrillingare far too many to ignore. It is not only flexible and fast, but it is a cost-effective mechanism as well. Besides, traditional drilling cannot be used in all types of materials, but laser microdrilling can be used for any material with any kind of thickness. For quality and rate of production, laser micromachining is suitably tailored for every industry requirement. It is the best solution for the manufacturing industries in the long run.

For the shaping of extremely porous structures, the femtosecond laser has established itself as a unique instrument. A femtosecond laser micromachining system can be used for the ultimate in ultrafast machining. Laser micromachining can be used to weld, cut, drill, and make other material modifications to achieve features on the single or double-digit micrometer level.

Femtosecond lasers facilitate high precision processing without any heat effect on the substrate: direct writing, mask projection, and interference. The femtosecond laser micromachining system (femtofab) is a multi-utility laser machine designed for numerous industrial applications. For instance, the unique porous structure of polyurea aerogel has many attractive applications, including lightweight thermal capabilities. Picosecond and femtosecond laser micromachining has developed as a reliable tool for precise manufacturing of these materials and electronic industries.

These processes are used to make fine drilling and machining into hard metals and ceramics and soft plastic to form various nano and microtextures to improve surface functions and properties in products. By aiming the laser beam on the surface, direct writing is performed. Initially, the micromachining industry regarded the femtosecond laser just as conventional wisdom perceived back in the early 1990s.

Modern laser micromachining and texturing services have taken another big step forward thanks to femtosecond laser micromachining. These systems are protected by a Class 1 equivalent laser safety enclosure and controlled through an advanced engineer software window.

Rarely anyone expected that so many industries around the world would rely on it for many applications. The configuration is selected and carefully tuned according to a specific laser micromachining application.

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. Laserod Technologies offers some of the best lasers cutting services in California and also specializes in drilling holes small to large by the laser drilling methods of percussion and trepanning.

Laser cutting is applied to different materials and components where reliable, quick, and force-free processing is needed for complex contours. In this technique, lasers create narrow kerfs and achieve high precision cuts. This approach demonstrates no distortion, and in many situations, post-processing is not required since only a limited amount of heat input is subjected to the material and mostly are dross-free.

Nearly all kinds of metals can be micromachined by laser; the most common applications are silicon, steel, stainless steel, and aluminum. Other parts micromachined by laser are made of wood, plastics, glass, and ceramics.

Laser micromachining is cost-effective for large scale as well as small-batch production compared with alternative techniques such as die-cutting. Localized input of laser energy provides small focal diameters, small kerf widths, high feed rate, and minimal heat input, this is a significant advantage of laser cutting.

Laser micromachining of silicon substrates

In addition to metals, a wide range of other items, including semiconductors, plastics, organic materials, ceramics, paper, graphite, diamonds, and composite materials, can be micromachined with the laser. With very high precision and low heat input, mono and poly-crystalline silicon wafers can be cut at high speeds using the same ablation process for edge isolation and drilling.

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.

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.
