Common Defects Found with Spin Coating

Spin coating is a fantastic way to protect sensitive application surfaces or add a layer of specialized material at the microscopic level. However, some problems may present themselves if this process is done incorrectly. In today’s blog, Coating Systems examines common defects found in spin coating. Comets Comets, unfortunately, happen regularly with spin coating. Comets occur when a relatively large particle, bigger than the ones in the coating, interrupts the normal flow of the coating on the spinning wafer. These particles can come from dirt or dust on the workpiece or from within the coating itself. Companies can solve the problem of comets by working in cleaner…

Industries That Need Spin Coatings

Spin coating involves applying a thin coat of liquid over an object while the object is turning. The liquid then cools, and some parts of the coating may evaporate, to achieve various effects. The main idea is that the spinning action spreads out the coating to a perfectly even thickness over the desired material. Spinning also dries the liquid in a controlled environment. Centripetal force allows this process to happen. Coating Systems explains industries that utilize spin coating as a way to protect or enhance their vital products. Semiconductors Semiconductors, most notably computer chips and microchips, benefit from spin coating techniques. Film over semiconductor wafers not only…

Coatings Systems Explains Why the Aerospace Industry Needs Perfect O-Ring Seals

O-rings are easy to overlook, until they don’t work. That’s what happened on Jan. 28, 1986, when the Space Shuttle Challenger exploded 73 seconds after liftoff. A brittle o-ring caused the seal to fail on a solid rocket booster before rupturing the main fuel tank and engulfing the shuttle in a superheated ball of flame. Seven astronauts died and the nation mourned their heroes. Coating Systems explains why the aerospace industry needs perfect o-ring seals. Hydraulics Modern commercial airliners rely on hydraulics for the many moving parts of an aircraft. For example, pilots control the landing gear with hydraulic systems. Hydraulics require precise o-rings to prevent hydraulic…

Industries That Use Die Cut Seals

Die cut seals work in concert with flanges and gaskets to ensure joints in pipes and pumping systems don’t leak. These types of seals are made in precise shapes to match the flanges and gaskets, thereby making the tightest seals possible. Die cutting makes mass production of these seals more cost-effective compared to other methods. In today’s blog from Coating Systems, we look at industries that benefit from die cut seals. Food and Beverage Food and beverage manufacturing and dispensing requires die cut seals to keep liquids from leaking. Food-grade seals are made of compounds approved by the FDA for use in American beverage manufacturing facilities. Seal…
