DIY Heatsink for Small Transistors

Step 5 Assemble

-- First, cut a small piece of heat shrink tubing. It should be slightly longer than the tab.

-- Test fit all the parts.

-- Apply a small amount of the thermal paste to the transistor (flat side.)

-- Slip the heat shrink tubing over the metal tab, then carefully slide the transistor in, being sure the flat side contacts the heatsink.

-- Shrink the tubing to complete. A heat gun, electric stove or other heat source will do.

During initial use, the heat generated by the transistor will only shrink the assembly more, making a more solid unit.
