Arrived fast and extremely well packed
In general very good quality. Initial unit had considerable bow across width but this part was very quickly replaced by an acceptable heatsink.
Finally lots of fins and THICK base! 50W LED here we come!
Great to be able to find parts for our project locally but still be at reasonable prices (unfortunately harder and harder to do for a lot of things)!
Very glad I came across Heat Sink USA. Great product, great service, incredibly fast delivery.
The machining work did not meet specifications.
While the extrusion is of good quality, I paid
additional for an area to be machined flat.
"Surface error (flatness) to equal or better
than farside (flat side) of extrusion stock."
Two of the five pieces have significant tooling
marks which I hopefully can lap-finish flat. The
other three - I will have to have re-machined
because of the significant surface ripples left
by the machinist.
5.375" x 12in used in a custom rectifier. Great value. Received order promptly.
This heat sink will be used in a 2M linear amplifier and the heat sink forms the top of the enclosure. It looks great! Excellent machining and precise cuts.
The heat sinks work and look great. The custom machine work was exact to my specification. I will be ordering more.
