Product Information

Fans are your best option for your PCB’s heat management. To enhance your fan’s safety and efficiency, you’ll need the right parts.

PCB spacershelpcomponent mounting on PCBmaintain space and positioning ofcircuit board componentswithin your PCB. Both can have the same shapes. You can get a hexagonal standoff or a hexagonal spacer. You can also choose a round standoff and round spacers. Filters are another example. Fan filters remove any dust or small particles from the fan’s airflow to prevent any internal damage. You can get a metal fan filter – stainless steel and aluminiumis one example – or a felt fan filter. Aluminium and stainless-steel filters allow more free air flow, with more dust as well. They’re easier to clean than felt, and have a sleeker design. Felt is harder to clean, but keeps the dust out. Also, the felt fan’s design takes up more space. Poor heat stability, which is why additives are put in during manufacturing. This helps stabilise the material at higher temperatures. For your convenience, you can also get fan filter sets, which provide you with a finger guard, filter cover, mesh filter and felt filter. They are commonly used in home and office furniture, computer desks, and audio/visual equipment. Grommet AccessoriesTypically, a cable grommet is round in shape and is made up of two pieces—the inner and outer pieces. The inner piece is fitted into the hole in the metal panel or application and the outer part fits over the inner piece, creating a seal. This seal helps keep out dust, dirt and moisture from environmental impacts or to provide a secure and firm grip on the wire or cable. Materials & types of cable grommet Mounts help position and secure your fan. You can even get anti-vibration rubber fan mounts to reduce noise generated by the fan. These type of fan mountsare usually made out of an elastomer, such as silicone rubber or Acrylonitrile-Butadiene-Styrene (ABS).

Different types of grommets can offer specific benefits depending on the usability and working conditions, such as electrical wire protectors (EWPs), IP54 sealing, and high-heat resistance. They are widely used in various industries, including data centres, telecom and automotive industries and manufacturing facilities. Because PCB solutions come in a choice of materials, it’s important for you to know each of those materials’ properties. This knowledge will give you an idea of the performance you can expect from the solution. With that in mind, here’s an overview of common materials for PCB hardware: Heat-Stabilised Nylon: shares the same mechanical properties as Nylon 6/6, but also has the advantage of heat stabilisation. Stand up to 125˚C (257˚F) temperatures. Impact-Modified Nylon: extremely high-impact strength at low temperatures and resistance to heat distortion, compared to Nylon 6/6. So what exactly is the difference? Spacers are unthreaded, with a through hole. Standoffs are threaded on both ends and come in both male and female designs. Sometimes you’ll see the description “threaded round spacer”. This is a standoff, because it’s threaded. The bottom line is, they have the same purpose. The difference is in whether or not they’re threaded.

Materials vary. Use ceramic spacers for extremely high-temperature applications. PCB plastic spacers, such as a Nylon PCB standoff, offer good corrosion resistance and are cost-effective for mass production, while still having good mechanical properties. They’re also the preferred choice over metal if you need a lightweight alternative. Melt temperature of 100˚C - 260°C (212˚F to 500°F), heat deflection temperature of 92°C (198°F) and tensile strength of 1,000 to 3,625 psi (Flexible PVC) / 4,930 to 9,000 psi (Rigid PVC). Some of its weaknesses can be offset by copolymerisation with other monomers. For example, it can be copolymerised with ABS, giving it high stress and impact resistance and higher tensile strength. You might also need an LED light pipe, which transmits light from the LED mounted on a PCB. LED light pipe technology translates to excellent visual performance, providing uniform lighting. It also significantly reduces shadows and glare. Another big advantage: they’re easy to install.
