Overwatch - Hardware - Daughter board installation

Many EQSS Overwatch kits contain daughter boards. Correct installation is critical to reliable performance.

The correct fitment of these daughter boards is crucial to the reliable operation of an Overwatch system. This Tech Doc is an addition to the instructions within the EQSS Overwatch Installation Manuals, and is intended to highlight the importance of good preparation and correct PCB pad dressing.

Steps:

First clean mechanically all solder joints where the EQSS Overwatch Daughter board pins will connect to the scissor control board. All glue/silicon/conformal coating must be removed, and then the control board contact points can be cut back with electronics side cutters.

Use a fine pair of angled side cutters to trim down the signal pins. Ensure the pins are cut flush with the PCB to allow the spring pins from the Overwatch daughter board to make suitable and secure contact. The photos below should be used as a guideline to ensure reliability in the final assembly. 

                               

          

         

When all preparations have been completed for the attachment of the daughter board, the final bolting down of the daughter board onto the scissor control board can be finalized. To assemble - use whatever method is easiest for you, but DO NOT USE SUPER GLUE to hold down the spacers during assembly, as most likely it will also end up on the spring loaded pins - rendering them non usable. When all spacers and screws are mounted loosely in place, gently wriggle the daughter board until satisfactory seating of the pins is achieved. Then carefully and evenly complete the tightening of the screws.
