I have started a new amplifier project and so far its working except for pulling heat from the SMD fet. Over the past few weeks i have bought a few test boards and change the designs a few times, getting better and better. Also learned from this video ( ) That Dave did, and implemented it into my latest design. I know his video is a little older and things have changed, has anyone got some input and suggestions for me to succeed with my design ?
My goal is to build proper output board to drive 20-48 IRF630 Fets in Class A mode for an amplifier. This 20 fet version works i had it running but heat was the issue with the single layer version of my first board. I assumed ( yes we know what that means ) that i could put a piece of heatsink on the top part of the fet to cool it. ( wrong )
Attached a few photos.
