When we are speaking about monolith drive preparing for soldering, we should remember about one of the most important steps – grinding.
Grinding – is a special process of compound erasing from the bottom side of monolith device. During this process, engineer have to be very careful, because he can damage the cupper layer and make further monolith recovery absolutely impossible.
We always recommend our customers to use cheap jeweller sandpaper with the smallest size. Unfortunately, sandpaper can erase the cupper contacts because it’s surface can easily erase all parts of our monolith device – plastic and metal. So, what we can use instead of this “barbarian way”? The answer is very simply – we can use special Fibreglass Pen Brush! It allow to erase the compound layer of monolith very careful without making injures to cupper scheme. We are using the most common fibreglass pen by “STAEDTLER Mars technico” brand. Usually this fibreglass brushes are using in PCB grinding, when enginner need to erase a layer of compaund from board PCB and get access to internal roads. We can also use it for monolith grinding 🙂
