Build Log: Final Install of the MiniKits RF Amplifier

After the pcb was finished (minus the power MOSFET), the heat sink needs to be drilled and tapped for to mount the standoffs and the MOSFET pair. Source a 150x80mm heatsink on Amazn. The bottom is at least a quarter inch thick. I’m using M3-0.5 standoffs for all pcb mounting. It’s actually pretty hard to find a 2.5mm drill bit. I tried a metric tap set from Dubro, but snapped the bit in the first minute. I ended up purchasing a 40 pack (cheap imported bits). These bits performed way better.
