Printed Circuit Boards (PCBs):

Electronic adhesives are used to bond and secure components such as resistors, capacitors, integrated circuits (ICs), and other electronic components to the PCBs. Many solder joints on PCBs are being replaced by more flexible conductive adhesives. In order to protect sensitive components, adhesives are applied to PCBs as ball-shaped tops, coatings, or bottom fillers for chips. To meet various market demands, a wide range of adhesives is available for PCB bonding applications, particularly for chip packaging on electronic circuit boards. Conductive adhesives with thermal conductivity are commonly used for heat dissipation in power electronic devices. For example, they are used to bond heat sinks, and their thermal conductivity helps reduce thermal stress to prevent performance loss or failure of electronic components.
