Adhesives for SMD Assembly and Reflow Soldering
Before soldering, components with pin contacts or SMDs are often bonded to the PCB with fast-curing adhesive. This allows, for example, several capacitors, electrolytic capacitors and coils to be positioned on a circuit board to prevent their falling over or sliding out of position on the PCB.
