AMC - Advanced Mezzanine Card - Carrier FAQs

Is the 4mm return spring slot in the Full Size AMC Carrier PCB board always required at the top and bottom locations to accommodate the carrier handle?
The return spring slot in the carrier PCB will always be required in both top and bottom. The reason is that the handle uses a slider to provide the rotation lock as well as activate the microswitch. When the microswitch is not used in one or the other position the slider still provides the rotation lock function and therefore requires the return spring.
What microswitch do I use on the Full Size AMC carrier and modules?
Panasonic has discontinued their NAIS switches. Please use the following SMK switches.

It is important to note that the handle slider design was also modified to work with the new SMK switch.
Please ensure you have the latest handle kit (with slider) if you intend to use the SMK switch with older AMC Carrier handle kits - the older slider version without the cutout window in the side (as shown in the attached file) will not work for the SMK.
Did Panasonic phasing out their NAIS Microswitch?
As of December 31, 2007 Panasonic phased out their NAIS switch.
How does the Full Size AMC carrier handle interact with the microswitch?

Does Schroff have a datasheet on the insulator material used on the inside of the AMC carrier covers?
60849061 Insulator Material.pdf
Does Schroff have a datasheet on the EMC Gasketing used on the AMC Modules and Carrier?
Schroff uses a patented EMI gasket which allows for the shape, stiffness and size to be optimized for AMC modules and carriers. With this gasket there is nominally no overlapping of the component envelope of the AMC modules PCB. Customers can buy this gasket either from Schroff ( in special length for AMC modules ) or from mtc http://www.mtc.de/en.

Are Schroff's AMC components RoHS compliant?
Yes, all standard AMC components are RoHS compliant.
Do you have information of the AMC Carrier connector options?

For more information, please refer to the following connector manufacturer's websites.

What torque setting should I use to screw the M2.5 x 3.4mm screws into the struts?

Does Schroff's AMC Carrier accommodate a board thicker than the specification allows?
Any board thicker than the spec. allowed 2.4mm +/- 10% will not work with current AMC Carrier or standard ATCA handles, because the increased board thickness pushes the handle assembly outside the blade's horizontal pitch.
Does Schroff's AMC Carrier accommodate a board that is less than 2.4mm thick?
Schroff offers various bushing heights which are based on specific nominal PCB thickness. Three different bushing heights have been identified and are available which have corresponding identifying grooves:

For all standard Carriers we will now use the 4.00mm high bushing which specifically accommodates the 2.4mm PCB specified in AMC.0. It is very important that AMC Carrier designs include the Carrier PCB thickness and tolerance information so that we can specify the correct bushing height.

What LEDs are compatible with the AMC Module Quad (AMC.0 Rev 1.0) light pipe?
Many LED options are available to board designs. The following LEDs were identified by other customers. Each board designer should evaluate their own requirements. LEDs must be .6mm or less in height.

Has Schroff cycle tested the AMC Modules in a carrier?
Our AMC Modules successfully passed a 200 cycle test.

Does Schroff have a drawing showing the LED placement compliant to AMC.0 ECR 002?
Attached is the initial version of our drawing showing our new lightpipes and recommended positions for the AMC.0 ECR002 compliant LED configuration. Basically the customer can locate LEDs anywhere within the indicated zones behind the lightpipes. Of course the customer should check with their LED supplier for any specific details.
This drawing also includes the layout info for the ITT Cannon HDT0001 microswitch to replace the Panasonic NAIS version.
Per Req. 2.66b a minimum electrical creepage clearance of 1.5mm must be maintained to any metallic components of the latch mechanism. This means the maximum useable area for electronic components actually can't exceed 29.75mm (31.25 max. - 1.5) from Datum L. Since the lightpipe is non-conductive, we can ignore the creepage requirement and use this space for the lightpipe. In this case we have 29.9mm and don't infringe on the 29.75mm which can contain electronic components.
