What is a LED Light Pipe?
Light pipes, often called LED light pipes because of their use with LEDs, are physical structures (either a transparent plastic rod or an optical fiber) that are used for transmitting light lengthwise. Integrating LED light pipes is an extremely cost effective option that helps eliminate the multiple steps associated with transporting light from one location to another. Light pipes transmit up to 80% of emitted light making them useful for a broad range of applications including security equipment, medical devices, and communications equipment.

What is a Standoff?
Standoff Fastener Description
Standoffs are fasteners used to create space between printed circuit board (PCB) assemblies and are the standard fastener for mounting PCBs to prevent electrical shorts. Standoffs are similar to spacers but differ in that they are threaded.
Standoff Fastener Styles
Standoffs may be cylindrical, square or hexagonal in shape and come in male, female, male-male, or male-female styles. Standoffs are fabricated from various materials such as aluminum, brass, stainless steel and nylon. In addition, standoffs are often plated to meet application specific requirements.
Standoff Fastener Application Example
One application example for standoffs is the fastening of a motherboard (PCB) to a metal enclosure. In a typical scenario, male-female standoffs are fastened into pre-drilled metal ringed screw holes in the motherboard while the opposite end of the standoff is fastened to the enclosure wall. Mounting the motherboard in this manner prevents it from short circuiting.
Standoff Fastener Manufacturers
- Accurate Screw Machine (ASM)
- Amatom
- Bivar
- Concord Electronics
- ITW Fastex
- Keystone Electronics
- Lyn-Tron
- RAF Electronic Hardware
Configuring Standoff Fasteners
Since standoffs come in so many styles, sizes, and materials configuring the correct standoff for your application can be challenging. To aid you in configuring standoffs and other electronic hardware bisco has recently updated it’s RAF product catalog. Users can now browse and filter standoffs by style, material, diameter, length, thread size, and finish. Visit bisco’s online RAF product selector to learn more.

What is a PCB Card Guide?
Printed circuit board (PCB) card guides, also called PCB retainers, are short narrow strips of material formed into shallow tapered troughs. PC boards are inserted into the top of the trough while the bottom is secured to an enclosure wall. Most card guides secure the PCB in place through the use of pressure but some card guides utilize levers or screws to lock the PCB in place. Card guides are fabricated from a variety of materials including nylon, aluminum, beryllium copper, and stainless steel. By securing circuit boards in place, card guides prevent damage to PCBs caused by vibration and movement.
The Top Names in Card Guides
For many years Pentair, under their Schroff, Birtcher, and Calmark brands, has been the leading manufacturer of PCB card guides. In fact, many of their branded products such as Wedge Tainers, Lok Tainers, PCB Tainers, and Card Loks have become synonymous with PCB card guides. Other top card guide manufacturers include Bivar, Essentra (formerly Richco), and Keystone Electronics.
