Hi,
i currently have a problem with a memory chip and must replace it.
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.
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 stencil with all the default memory footprints or something?

0.8mm pitch can be done without stencil. In fact, for hand assembly, it is preferable not to use stencil and paste to prevent possible solder bridging.
Just use the solder on BGA balls, it is usually enough, though reliability may (or may mot) suffer.
Apparently, you need to use brand new chips, you don't really want to reuse and reball the chip without stencil.
