Hi Guys and Gals, How do I attach TO-3 ICs like this one to a prototyping board or pc board and add a heat sink? One of the 3 IC leads is attached to the metal top: Thanks in Advance

Let me create a scenario to better illustrate the problem I have 1500 pens that I want to individually actuate upwards with 3 different distances, ex: 10mm/15mm/20mm I thought I could use solenoids to do this, but I'm not sure if this is the best option and how accurate the solenoid will be...
