What is fabrication in construction?

Fabrication is an industry term that refers to the manipulation of raw materials (such as steel) to make machines and structures. The services of fabricators are needed to build the parts of a working system and then throughout the process.

What is the process of photolithography?

The process of photolithography uses photo light (UV light ~375nm wavelength) to pattern thin films of specialized organic materials (also known as photoresist or resist). Photoresist is a light sensitive material which changes in its chemical structure when exposed to UV light. Chemically modified photoresist is then removed in a chemical solution (also known as developer) to form a pattern of photoresist. Typically, a physical mask (also known as photomask) is used to control the exposed area of photoresist that sees a UV light.

How does metal deposition work?

Metal Deposition by Sputtering starts with creating high electrical field around source material (or target) of interest. Electrical field creates Plasma and removes material atoms from the source material. These removed material is then deposited on substrate of interested. High mean free path in vaccum ensures that most sputtered (or removed material) is deposited on the substrate of interest.

What is reactive etching?

Reactive Ion etching (RIE) is the process of transferring pattering in a top mask layer (e.g. Resist) to a second bottom layer (e.g. Silicon) using a plasma of etching gases (e. g. CF 4 gas). Plasma is formed when a high electric field breaks down the gas molecules to ions, neutral, and radicals. Typically, an electric field is directly applied to a substrate or wafer. These species are highly reactive and can etch thin film material in both chemical form or physical (sputtering) form. Chemical based etching occurs when reactant species (e.g. Fluorine radicals) react with material (e.g. Silicon) to form a byproduct (e.g. SiFx) which is volatile at room temperature and low pressure (~10 mtorr). Physical etching occurs when plasma ions are propelled under an electric field to strike thin film material at high velocity. In most cases, the combination of chemical and physical forms gives synergistics benefits in etch performance. For example, an etching profile can be anisotropic, or higher etch rates can be obtained for the same selectivity.

How fast does a silicon wafer spin?

Substrate (or Silicon wafer) is spun at desired rotational speed (between 1000 rpm and 5000 rpm) for selected time (typically 45 sec). Spinning parameters are obtained from a data sheet supplied by manufacturer. An example Spin curve for S1805 Photoresist is shown below:

Can metal be etched?

Certain materials (such as Gold) do not form etch byproducts with sufficient vapor pressure, and hence do not etch easily. Metal etch processes can also leave residue in parts of the etching chamber. These residues can cause yield issues when etching other materials (such as SiO2). For these reasons, the IMSE limits metals that can be etched or used as a mask in the Oxford RIE instrument.

What is fabrication process?

Fabrication is the act of taking raw stock material and turning it into a part for use in an assembly process. There are many different types of fabrication processes. The most common are. Let’s look at the types of fabrication processes in greater detail here: Cutting. There are many ways to cut nowadays.

What are the challenges of linking fabrication and assembly?

One challenge with linking fabrication and assembly processes tends to be the painting process. In many cases, parts leave the fabrication shop to go out for painting or go right to an in-house paint center. In either case, the flow is disrupted, and the delays cause more inventory. Again, use the CI tools at your disposal to minimize this impact—reduce cure time, reduce the changeover, make smaller batches, go to smaller, dedicated paint booths. Do what you can to keep coming closer to flow.

Why is Kanban important in manufacturing?

Fabrication processes are generally target-rich environments for continuous improvement. There are great chances for visual management and 5S to make processes run more smoothly. There are immense opportunities to reduce setup time to help lower lot sizes. Kanban helps with knowing what to make—especially on the extremely large machines. Right-sizing machines can help make flow better—smaller machines fit in smaller spaces that can be set up as dedicated lines for higher volume products.

Why is it important to right size machines?

It is best to “right-size” machines and put them into work cells if possible. That helps create flow. The biggest impediment to making flow in a fabrication shop is the preponderance of large, multi-function machines that take a long time to change between parts. This drives up the lot size, creating inventory.

What is welding in manufacturing?

What is the range of motion of a cutting head?

The range of motion of the cutting head is defined by the number of axes (i.e. a 3-axis machine). Punching is the act of a punch and a die forming a scissor effect on a piece of metal to make a hole in it. Obviously, the punch and die must be the same shape and size of the desired hole.

How to weld metal?

How is resin drawn?

Resin is drawn by vacuum through the reinforcements by means of a series of designed-in channels that facilitate fiber wetout. Because it does not require high heat or pressure, vacuum infusion can be done with relatively low-cost tooling, making it possible to inexpensively produce large, complex parts.

What is the use of an autoclave?

Pressure. Many high-performance thermoset parts require heat and high consolidation pressure to cure — conditions that require the use of an autoclave. Autoclaves, generally, are expensive to buy and operate. Manufacturers that are equipped with autoclaves usually cure a number of parts simultaneously. Computer systems monitor and control autoclave temperature, pressure, vacuum and inert atmosphere, which allows unattended and/or remote supervision of the cure process and maximizes efficient use of the technique.

How to make thermoset composites?

The most basic fabrication method for thermoset composites is hand layup, which typically consists of placing layers, called plies of either dry fabrics, or prepreg (fabric pre-impregnated with resin), by hand onto a tool to form a laminate stack.

What is composite molding?

Composite fabrication processes typically involve some form of molding, to shape the resin and reinforcement. A mold tool is required to give the unformed resin/fiber combination its shape prior to and during cure. Click on “Tooling” for an overview of mold types as well as materials and methods used to make mold tools.

When was stereolithography invented?

Stereolithography (SLA), patented in 1986, was the first fully commercial rapid prototyping technology and is still the most widely used. In the SLA process, the part model is built on a platform positioned just below the surface in a vat of liquid, photocurable polymer, usually an epoxy or acrylate resin.

Is sprayup a manufacturing method?

Sprayup processing, once a very prevalent manufacturing method, has begun to fall out of favor . Federal regulations in the U.S. and similar rules in the EU have mandated limits on worker exposure to, and emission into the environment of VOCs and hazardous air pollutants (HAPs). Styrene, the most common monomer used as a diluent in thermoset resins, is on both lists. Because worker exposure to and emission of styrene is difficult and expensive to control in the sprayup process, many composites manufacturers have migrated to closed mold, infusion-based processes, which better contain and manage styrenes.
