Flat back heat sink extrusion is a very common extruded heat sink, the tooling mold is not complex, and the cost of heat sink is very low and lead time is short. it's often used in the BGA or FPGA devices.
Surface treatment: black anodize or natural anodize or customized
Q: What characteristics make a heatsink a good one?
A: High heatsink surface;Good aerodynamics;Good thermal transfer within the heatsink;Perfect flatness of the contact area;Good mounting method.
Q: How long is your delivery time?
A: Generally it is 5-10 days if the heatsinks are in stock. or it is 30-40 days for mass production
Q: Do you provide samples ?
A: Yes, we could offer paid sample for prototypes testing if there is stock.we have thousands of standard heatsinks with different sizes and shapes.
