Introducing Heavy Duty PCB Retainers

Schroff (formerly Birtcher) is the global leader in the design and manufacturing of heavy duty PCB retainers and card guides. One of Schroff / Birtcher’s most popular PCB retainers is the 42 Series Wedge Lok. The 42 Series Wedge Lok is designed to secure PBCs in rugged and high vibration environments. 42 Series PCB retainers also offer a lightweight design making them ideal for military, defense, and aerospace applications.

42 Series Wedge Lok Key Features

  • Designed for cold wall applications
  • Aids thermal transfer from the PCB to the cold wall
  • Screw actuated
  • 3 segment, non-shafted design
  • Average clamp force (5″, black anodized) = 269 lbs
  • Max expansion 6.98 mm (.275 in)
  • Flexible mounting options
  • Available with gold chem film, clear chem film, black anodized, hard black anodized, or electroless nickel plating

Installing 42 Series Wedge Loks

42 Series Wedge Loks are designed for installation in cold wall applications. During installation Wedge Loks are first attached to the top and bottom of the PCB. Once the PCB is secured between the Wedge Loks it is inserted into cold wall channels in the card cage. Finally the Wedge Lok is actuated clamping the PCB to the cold wall.      

Configuring 42 Series Wedge Loks

Schroff / Birtcher 42 Series Wedge Loks are highly customizable helping them meet diverse and challenging application requirements. To configure a 42 Series PCB retainer for your application view the 42 Series spec sheet.

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.

Essential Hardware: PCB Card Guides

Card guides are key to the performance and reliability of most electronic devices. Card guides attach to the edges of printed circuit boards (PCBs) securely holding them in place. Since card guides are used in nearly all electronic applications they must meet the demands of many different environments. Card guides can be found in applications ranging from military communication equipment to network servers.

PCB card guides typically come in two primary mounting configurations: vertical and horizontal. Card guides are also available in many different materials, sizes and locking configurations. Other variations include card guides specifically designed for high vibration or static sensitive conditions.

Whatever your specifications chances are bisco industries can offer a PCB card guide that meets your requirements. We are an authorized distributor for several card guide manufacturers including Essentra (formerly Richco).
