Pcb Standoff Male Female Threaded Hex Standoffs Pcb Hex Standoff

PCB standoff is a threaded separator of defined length made of nylon used to raise one assembly above another. They are usually round or hex (for wrench tightening), often made of aluminum, brass, or nylon, and come in male-female or female-female forms. In electronics, they are frequently used to raise a printed-circuit board above a surface. Insulating standoffs keep two parts from touching each other, thereby preventing electrical shorts. When used to fasten cable connectors (i.e. “D” connectors) together, they are called “jack screws”.
In contrast, a spacer is an unthreaded piece of tubing that lets the entire bolt pass through. Since they cannot be tightened, they are usually round. Ever Hardware provides custom-made fasteners and customizable packaging.

PCB’s utility was based largely on its chemical stability, including low flammability, and high dielectric constant. In an electric arc, PCBs generate incombustible gases. The use of PCBs is commonly divided into closed and open applications. Examples of closed applications include coolants and insulating fluids (transformer oil) for transformers and capacitors, such as those used in old fluorescent light ballasts, hydraulic fluids, lubricating and cutting oils, etc. In contrast, the major open application of PCBs was in carbonless copy (“NCR”) paper, which even nowadays results in paper contamination. Other open applications were as plasticizers in paints and cement, stabilizing additives in flexible PVC coatings of electrical cables and electronic components, pesticide extenders, reactive flame retardants and sealants for caulking, adhesives, wood floor finishes, such as Fabulon and other products of Halowax in the U.S., de-dusting agents, waterproofing compounds, casting agents.
