1 Introduction
This document provides mechanical drawings suggesting different methods for holding the
DM3730/AM3703 Torpedo + Wireless SOM in place.
2 Force Test Results
Based on testing a limited number of samples, the DM3730/AM3703 Torpedo + Wireless SOM
requires 6 lb. of extraction force after one insertion when the mating connectors are the only
means of retention. After 15 insertion and extraction cycles, the extraction force is reduced to
4 lb. See drawing 1020632 at the conclusion of this document.
3 Hold-Down Methods
3.1 Logic PD Designed Hold-Down Clip
Logic PD has designed a hold-down clip that is included with the Zoom DM3730 Torpedo
Development Kit. The clip provides a method for securing the DM3730/AM3703
Torpedo + Wireless SOM with minimal impact on the surrounding space. See drawing number
1020633 and 1020244 at the conclusion of this document.
3.2 Enclosure
An enclosure can be built around the DM3730/AM3703 Torpedo + Wireless SOM and custom
baseboard. See drawing number 1020634 at the conclusion of this document.
4 Summary
This white paper provides several methods for holding the DM3730/AM3703 Torpedo + Wireless
SOM in place. The drawings included with this document offer examples of how these methods
could be implemented. Because every end product has unique requirements, it is outside the
scope of this document to provide a specific retention method for every scenario. Determining the
best solution for the end product is the responsibility of the designer, although Logic PD can help
with design solutions or reviews. Please contact Logic PD
