Hi,
i currently have a problem with a memory chip and must replace it.
The chip is from Sk Hynix and my plan was to create a simple pcb and just order the pcb with a stencil but unfortunately i didnt find any datatsheet or footprints from SkHynix.
So i was wondering if i could reflow the chip without a stencil?
The only information i could find about the chip is that it is a FBGA 170 Pins and looks something like this from micron.

.
Is there any stencil i could use like a default SkHynix stencil with all the default memory footprints or something?
Please excuse my english.
Hope someone could help me.
