Semiconductor Wafers and the Importance of Polishing

In the world of semiconductors and electronics, very thin slices of crystalline silicon are known as wafers. These wafers are used to create integrated circuits and solar cells. For the best results, a semiconductor wafer must have a smooth and very shiny finish. When the wafers are first created, they are ground down to a fine, thin surface. This leaves subsurface damage on the wafer that must be removed.

The Polishing Process

This is where silicon wafer polishing comes in. Special pads and a substance made of liquid diamonds or weak acids are used to deliver the superior shine required in semiconductors. Essentially, the unwanted texture left during the grinding and sawing process is buffed away. A special vacuum carrier holds the wafer in place, and the wafer is gently moved toward the pad until they make contact. With precise movements, the subsurface damage on the wafer is removed a bit at a time. In the end, a highly functional silicon wafer is created. This process is completed as quickly as possible to avoid possible contamination or damage.

Diamond Cubic Structures

It may be noted that as the crystal structures of the wafers develop, diamond cubic structures are created. Thus, when the structure is cut into wafers, there’s a potential for several different crystal orientations. The differing orientations have unique electronic and structural properties. The manner of cutting, cleaning, scoring, and notching can affect the efficiency of the wafer.

The Demand for Thinner Wafers

Today, there’s a growing demand for ever thinner, ever smaller wafers, and sometimes conventional manufacturing methods leave damage on the surface of those wafers. Effective polishing can remove that damage. Micro-defects and scratches don’t have to cause trouble or weaken the wafer. Instead, high-quality polishing gets rid of the uneven texture on the wafer’s surface.

Wafer polishing is essential to the efficient use of silicon wafers. Consider the benefits of a double-sided polish for meeting required SEMI standards and specifications.

Getting the Big Stuff Around Town

Getting the Big Stuff Around Town

The size and weight of farm equipment, industrial machines, tractors, and bulldozers makes it difficult to move from one location or job site to another. When you look online for “heavy equipment movers near me”, you will be able to find professionals with experience in moving massive machines or equipment. They will have the heavy-duty equipment needed for the job, and they can safely move your items from point A to point B. There are some things you will need to do before the equipment can be moved.

General Prep Work

Depending on the equipment or machinery to be moved, your transport company will give you advice on how to prepare for the relocation. You may want to wrap things like levers in bubble wrap, and fasten any window locks. It is also wise to secure the doors of any equipment with zip-ties.

Prepping the Machine

When you prepare for the move, check with the manufacturer’s manual on specific instructions for your machine. If you have misplaced the manual or never received one when you took possession of the equipment, you can generally find a copy on the manufacturer’s website. You can also call and ask about moving instructions. You might be advised to empty the engine of all fluids, disconnect the batteries, and secure any loose parts with industrial tape or zip-ties.

Getting the Permission

The Federal Motor Carrier Safety Administration has outlined specific requirements for the transport of heavy equipment. It even specifies how they should be secured. Although the moving company will be familiar with these regulations, you are responsible for securing the necessary permits to complete the job. The equipment that is being transported may be unable to traverse certain roadways due to power line locations, bridges, or tunnels. There can be legal complications if the right permission has not been filed and obtained.

On the day of the move, be prepared. Have all the open parts covered and protected from weather elements. Have the necessary loading equipment, and leave the job to the professionals.

Maintenance for Hydraulic Systems

Maintenance for Hydraulic Systems

Hydraulic power is created by a circulation of pressurized fluid, such as a water-glycol mix or water-soluble oil,  to a motor capable of converting it into a working function that produces more power than a traditional mechanical or electrical system of equal size. Because of their impressive accurate yet rapid responses to controls, hydraulic systems have found many uses across many fields. Some of their more demanding jobs involve heavy industrial machinery, automobiles, and aircraft. Their importance to the successful operations of many businesses requires that careful maintenance program be enacted to keep the systems in good working order.

Multiple Components Need Attention

There are many elements of a hydraulic system, such as oil seals, hydraulic cylinder parts, valves and hoses. Each component has its own maintenance needs, but having regularly scheduled maintenance plan that checks priority areas can help avoid long-term damage and machine downtime. Some of the recommended areas of attention include the following.

  1. Filter indicators. The indicators assess the contamination amounts being caught by the filter. It can show the level visually through either a gauge or a pop-up indicator. If it shows that the filter has reached the maximum holding capacity for contamination, it is time to replace the filter.
  2. Sample the oil. Because the hydraulic system is heavily dependent on the successful flowing of fluid throughout the components, checking the oil allows you to test for solid particle contamination or other problematic elements in the oil. Test from an active return line for the best reading.
  3. Check your temperatures. The temperature has a significant impact on the viscosity of the oil in your system. If the viscosity doesn’t meet the working range of the system, continually pumping oil can reduce the lifespan of the system over time. Too high of a temperature can cause a pressure drop in the lines, which may lead to cavitation.

Taking care of the components of the system helps preserve the functionality and efficiency of the machine. Keeping track of small areas of repair can help avoid major malfunctions down the road.


How Clothes Are Dry Cleaned

Many special occasion clothes as well as comforters are dry clean only. Dry cleaning is a process that cleans fabric with a chemical solvent instead of water. From washing to the dry cleaning conveyor, here is how the process works.

Wash It Up

Before clothes are dry cleaned, the pockets are gone through to remove random objects before they damage the clothes. Fragile fabrics are put in a bag to keep them intact. If there are stains, a stain treater is applied to the spot. All the clothes are tossed into a washing machine and a chemical solvent, typically perchloroethylene, is added to the machine clothing. The temperature is kept consistent because if it gets too hot it can damage the fibers. Since there are concerns that these solutions contribute to polluting the planet, many dry cleaners are turning to environmentally safe products. Once everything is combined, the unit agitates the laundry until it is clean.

Squeeze It Out

Once the clothes have been washed and rinsed in the solvent, the chemical is drained from the machine. The drum then spins the rest out until it is almost gone. The solvent is recycled for reuse in another washing. When the spin cycle is finished, a warm blast of air is sent into the drum to dissolve the last remnants of chemical. That steam is collected and chilled to extract the last bits of detergent out of it.

Hang It Out To Dry

When the clothing is clean, they are deodorized to cool them and to wring the very last trace of solvent from them. The articles are hung up until they are completely dry. They are then pressed and hung up again on a conveyor system. The customer is called to tell them that their item is ready for pickup.
