It's been a while since our last release of prototype sintered pads, one of the shortcoming we found was the potential delamination of lining material from steel backing plate after some really extreme heat cycles.
So we implement a new process to improve the bonding strength between two different material (lining and back plate) by using a high strength steel backing plate which is more resistant to heat and warping. The backing plate is also plated to provide a better media for bonding under high heat.
This new process has successfully eliminated this delamination issue, it also improves the modulation capability due to the plating makes two different material (lining and backing plate) works together as one. The result is very satisfactory based on the recent test result on Thunderhill tracks reported by Ron.
Here are some pictures of the new sintered pads (due to the metallic surface is highly reflective, so the pictures didn't come out good as normal)
