When I do prototyping I solder my PCBs by hand. That works fine most of the time, but I run into a problem when I have to solder chips with fine pitch (Google for VQ100 to get an idea of what I'm working with). The problem is not the soldering by itself but keeping the parts in place once the pins are aligned to the pads.
Now I'm looking for an adhesive that lets me temporarily stick a large SMD component onto the board so it does not slip away as soon as I touch the pins with my soldering tip.
During a Google search I found a log of SMD adhesives, but all of them are resistant to PCB cleaning substances. I need the exact opposite. Something that lets me temporarily stick a part onto the PCB and dissolves fast in PCB cleaning chemicals (I use isopropyl alcohol if that matters).
Something with the sticky properties like thick honey would work except that I'm looking for a more professional solution.
I'm certainly not the first one to look into this, so there must be a ready made product out there, right?
