Can I use type IV solder paste on 0201 application?
If it can be used, can you explain why it is an acceptable choice?

Type 4 would be the paste of choice for 0201 applications. Rule of thumb is the stencil aperture size should at least 5 times larger than the average paste particle size. For type 4 the average particle size is roughly 30 microns. 5x that is 150 microns. Aperture size for 0201 are typically 200 to 250 microns.
