Not recommended, because some solder will wick down to the other side and the component on top will not solder correctly.
Remedial measure:
Remark: Before designing via-in-pad, don’t forget to talk to your PCB fabricator to find out what their capabilities are, and how much extra this costs.

There is nothing about weight in the substrate datasheets I found.
Between CEM-3 or FR4, which is the lightest material ? What is the average weight by surface for CEM-3 boards ?
I have a small hobby project in which I want to include the Kingston EMMC04G-M657 eMMC chip. This chip comes in BGA packaging with 0.5mm pitch between balls. I want my board to be cheap, so I’m laying it out for a 4-layer PCB using rigid board design rules of my supplier. I’ve put these rules into KiCAD and it seems to me that there are a few pins that I can neither escape from the BGA with a trace nor disappear with a via. How can I move on?
Is there a general rule as to how much clearance you should add to through-hole components’ holes to allow them to fit easily? For example, if I have a component with 1mm pin diameter, what should the diameter of the holes for it’s pads be?
PCB Milling boards Boards (circuits boards, printed circuit boards, …) can be manufactured in many ways, in this article, there’re two PCB milling ways we
PCB thickness is one of the important factors to consider when manufacturing printed circuit boards, it affects the conductivity, resistance, and performance of the PCB.
When you receive a quotation from a PCB supplier, a question inevitably pops up: What determines the cost of a PCB? How can I find
