Some reasons are making the electrically conductive adhesives for PCB a bit more popular than soldering. The electrically conductive adhesives make it easier to hold electrical parts in place, especially when temperature sensitive. By using an adhesive, bonding becomes easier and possible. You can achieve strong bonding by using conductive adhesive for PCB. Website:
