1. LED Solder Press  Status Report Presentation  Senior Projects I  By Ryan Bigl &  Kyle Levesque

2. Background Info  This project is for a small business called LEDdynamics, located in Randolph, Vermont.  “LEDdynamics is a custom engineering company specializing in the design and integration of LED technology for end-user and OEM applications.”

3. Problem statement Design an automated miniature solder press that will…  Be able to solder pre-glued surface mount LED emitters to a metallic circuit board.  Be able to test the LED after completion  Must be faster and more efficient than hand assembly.  System will not need human aid, after initial setup is completed.

4. Process Description  Drill Metallic Mounting Circuit Board  Prep soldering area with flux  Glue in surface mount LED’s  Solder the LED leads  Test for failed product

5. Solutions  Build a X table with a set jig for metallic circuit boards.  Make a single press/ dual soldering iron system with wire fed solder.  Test the LEDs inline with solder station.  Allow user to initially select predetermined board size and stores data throughout the run.
