STATEMENT OF WORK (SOW)

DMEA 25-TBD

31 March 2025

Project Engineer:

1.0 SCOPE: Procure Hot Bar Reflow Soldering System to establish a reliable and precise soldering capability for connecting QRE Sword technology flex circuits to rigid circuit boards and Iridium modems designed with fine pitch footprints in the PAS Lab. This acquisition will enable DMEA’s Quick Reaction Engineering (QRE) Iridium modem-based technologies ensuring high reliability soldering performance.

1.1 TITLE: Hot Bar Reflow Soldering System.

1.2 APPLICABILITY: Recent environmental testing of QRE Iridium technologies revealed a significant reliability issue; specifically, modem connectors exhibited unacceptable weakness leading to failures at cold temperatures under environmental stress. To mitigate this issue, the QRE team is developing and implementing a more robust soldering approach to eliminate the connector based issues.

1.3 BACKGROUND: Pulse heated Hot Bar reflow soldering is a process where two pre-fluxed, solder coated parts are heated to a temperature sufficient to cause the solder to melt, flow, and solidify, forming a permanent electro-mechanical bond between the parts and solder.

1.4 PURPOSE: To create a consistent and reliable electromechanical bonds between flex and rigid printed circuit boards. The Hot Bar Soldering system allows for selective heating on specific areas that are very difficult to solder with traditional soldering methods, enabling rapid heat application while maintaining precise temperature control.
