s17 BM1397AG asic chip resolder - What to use as stencil?

[JessieJames13]

Usually a stencil is used when applying the solder paste to the BM1397AG chip, however right now I dont have a stencil and ordering from alilbaba will take weeks to arrive.

Does anybody have any alternative tricks things to use

Honestly, you don't need to use stencils. Soldering iron, flux, and a bit of soldering lead should be enough to reball an ASIC chip and BGA hot air when you are going to resolder the ASIC chip to the hashboard.
You only need a stencil if you are in rush but for a single 2 or 3 chips for me, I don't need a stencil.

Ok, I found a video you can use on how to reball it without stencil check this link below.

I was thinking this also BitMaxz, but the problem is estimating how much solder to use.
Going to check the video now.
