PC104p-Chassis


Dynamic Engineering is pleased to announce the PC104p-Chassis. Suitable for PC104, PC104p and PCI-104 applications. The chassis is based on an extruded aluminum outer housing with machined end caps. The internal card cage is isolated with bumper pads from the external housing to provide vibration and shock absorption. A heat sink is built into the internal and external walls of the chassis on three sides to aide in heat transfer. The bottom surface is extended to create a mounting flange which can also be used for cooling in conductive cooled systems. The end caps are machined to include a gasket for water tight operation. An EMI gasket is available.

1-11 modules, and custom lengths, 12 and 28V power supplies, custom machining and silk screening are available options.

The PCI-104, PC104p, PC104 Chassis comes in base sizes : 1-11 slots [an extrusion is used for the main body of the chassis making any length possible]. The models are adaptable to allow 1, 2, 3, 4, or 5 cards to be mounted in the 5 slot unit and any number up to 11 in the larger units. In a typical system the first position in the stack would be the power supply, the second the CPU and the rest IO or storage. With the range of cards available for PCI-104, PC104, PC104p and IP available most applications can be implemented with off the shelf hardware and a chassis. The PC104pPWR12 can make a good power supply for PCI-104, PC104 and PC104p stacks or stacks with mixed cards. The chassis is flexible and works with any assortment of cards. The chassis is rugged and can work in a variety of environments. The chassis is water tight at low pressures with the standard gasket.


To use the chassis: First, build your stack with standard spacers etc. Second attach to the rear plate with spacers and screws. Third add spacers to the front side to fill in the unused positions and attach to the front panel. Four screws and 4 nuts for the stack plus 4 more screws for the side supports. "rapid assembly!" We can provide additional assembly and test services to install the power supply, CPU, IO etc. shipping a completed unit to you.

To complete with the outer housing: slide the assembly into the outer housing and secure that. The outer housing is designed to have gaskets and provide a sealed environment. The front and rear outer housing can be used to mount your system connectors. Dynamic Engineering can arrange to have custom cut-outs, and silk screen for your chassis We can design connector plates to interface with cables should that be desired. The end cap plates for the internal chassis can also be cut-out to allow for deeper connectors.


The internal and external heat sink built into the chassis wall can allow internal air cooling too be used in a sealed environment. With a fan card added to your stack the heat from your CPU etc. can be transferred to the sidewall and to the outside with the aide of the heatsinks. Spring steel provides a direct thermal path from the internal frame to the external chassis [not shown in pictures].

The internal hardware is rigidly mounted to the stack and shock / vibration isolated to the side wall with the bumper pads. The shorter boxes come with 8 bumper pads for the corners plus two for the end caps and the longer [7 slots and more] come with 12 bumper pads plus two for the end caps. The end cap pads are shaped to allow maximum area for connector penetration.

Plenty of room is left for cabling along the sides of the chassis from the cards to the panel. The cable area is approximately 1 x 3.375 on each side of the chassis. The cable routing space coincides with the connector area of the PC104p to make it easy to install and secure the cables within the internal frame. With customized panel cut-outs you have have any IO you require.

The end plates are designed to support gaskets. The base chassis is supplied with a silicon gasket. EMI gaskets are an available option.

The bottom plate comes with mounting slots to make it easy to attach to your system. The bottom plate can be used for additional cooling in a conductive cooling environment - cold plate attachment etc.

The PC104p Chassis and enclosed stack will need power distribution. Any PC104 compatible supply can be used. The PC104pPWR12 and PC104pPWR28 designs are recommended to convert from 12V or 28V [14-36] power rails to the +5, +3.3, +12, -12 and -5.5 you may need for your stack.

If you have custom requirements please call or e-mail us with the details.


PCI-104, PC104p, PC104 Chassis Features

Stack Height	Standard PCI-104, PC104p, PC104 cards - up to slot count number of modules. Models for 3, 4, 5, 6, 7, 8, 9, 10, 11 or custom available. Larger units can be used with fewer cards and additional spacers if desired. Shorter units for 1, 2 cards can be manufactured for space constrained applications. Remember to count blank slots where double high modules are mounted or for extra airspace if a fan is used.
Dimensions	External Dimensions outer housing: 6.050"[top] x 5.300"[side height] x length based on slot count. 7.050" bottom with mounting flange.
Weight	Empty weight of chassis including internal housing and no cards : 5 lbs for 5 slot model, 6 lbs for 7 slot model, 7 lbs for 11 slot model.
Materials	Outer chassis extrusion: Aluminum 6061 Outer chassis plates:Aluminum 6061 Hardware:Stainless Inner chassis supports:Aluminum 6061 1/4 hex inner chassis end plates:Aluminum 6061 Bumper pads: 60 Durometer Red Silicone Rubber
Thermal	Built in heat sink on side and top wall internal and external. Spring steel end supports tied into the card mounts to allow for direct heat conduction from the stack to the frame for passively cooled systems. Spring steel not shown in photo's. 4 locations at each end for even pressure and maximum conduction. Tie your ground plane to the mounting holes to take advantage.
