While the suggestion was made 2 years ago allready, i think instead of necro posting, i make a new own one with more info and though of how to properly implement it.
What is it?
Well as the name (and title implies) (and many propably will also allready know allready) its a HEAT Warhead with 3 Strong magnets, which offer a strength of 45kg, resulting it it, beeing able to be easily fixed to any tanks, even on vertical or inverted slopes or even under the tank. Equipped with a Time fuze (unlike a certain Japanese HEAT warhead on a stick) it offers time to get away.
Overall there were 2 Versions which are pretty similar:
1. HHL 3 (Click to show)
Rounded shape, 3 kg full weight, HEAT Warhead 1,5 kg of Hexogen and Fp.02 (TNT) filler. The liner is made from Iron/Steel
2. HHL 3,5 (Click to show)
The more common and well known funnel shaped Warhead, 3,5 kg full weight, HEAT Warhead 1,7 kg of Hexogen and Fp.02 (TNT) filler. The liner is made from Iron/Steel
IRL these were used for Tank Close Combat, running to it, or waiting in a foxhole for it, fixing the Mine to it, pulling the fuze and getting away. Both Versions penetrate around 140mm RHA, meaning no tank, even from the front will be save, IF you can get close enove to fix it to them. Compared to the currently in game Remote detonation charge, it has the advantage of beeing HEAT and not manually fuzed instead on a time fuze.
They work by placing the Warhead on tanks, Reinforced structures, Cupolas, Steel Turrets, bunkers and more. It will penetrate up to 14 cm and kill the crew as well as damage the structures by Shrapnell and pressure. The Fuze is 7,5 seconds long.
With the addition of Iron Spikes on the Magnets, they can also be used on wooden structures.

To use it, the Fuze is inserted into the top and savety removed. The Iron Rings are removed from the Magnets.
The Mines are then placed either on the side of the hull or Turret, idealy where most of the Crew or important modules are located. The funnel shape top is to be used as the grip, the fuze can be activated befor fixing it to the target, to reduce the timeframe upon detonatio. Refer to pictures:
The Penetration results in 3 to 5 cm diameter holes, effect is not stopped by internal reinforement plates and other material.
The Resulting Shrapnell and Pressure have devestating and destructive power.
Tests showed, that the cone of shrapnell at a detonation range of 1m was up to 0,8m diameter and at a range of 2m up to 2m diameter.
Picture 3 and 4 show penetrations of 10 cm plates.

To fix the Mines to Wooden reinforced structures, as well as Tanks with Wooden covering, simple iron thorns can be crafted and if needed fixed to the magnets.
These can be made from simple iron pieces.
In game, implementing a working “place on” function would be somewhat difficult and a hassle.
Back in the good old days of Red Orchestra 2 Heros of stalingrad, they were implemented as sort of Grenades, where the player would throw it, however it isnt the Russian RPG-43, it cant be thrown, instead i suggest it to be similary implemented like an engineers building, when holding it, it shows a white “possible” placeing, pressing LMB a short “construction” timer, with a basic “placing” animation would be easy and would make shure that you can easily place it where you want for the intended greatest effect.
