New heatsinks not touching chip surface and fall of again.

I executed the heatsink modification according instructions. The 2 old ones were both lying on the bottom. Then I glued the new ones on top of the chips and pressed gently. Done? I started to close the case but suddenly one of the heatsinks fell of again! After closely investigating I noticed that some surrounding SMD parts are (L2, L3, C11) higher then the surface of the chip! In other words it is not possible to mount the heatsink in such a way that it touches the chip. The only solution is to cut the new heatsink to fit the chip. Do I have different pc boards or why did not anybody else has this problem? What I‘m doing wrong? Chris DJ2NL
