Surface Mount Adhesive Systems

Master Bond has developed many dielectric and conductive surface mount adhesive systems (SMAs) for use in various electronic applications. These can be either one component compounds which cure with heat or two component chemistries which can cure at room temperature. Electrically insulating surface mount adhesives offer excellent bond strength and can hold components in place during solder reflow process. Electrically conductive SMAs are employed in various advanced electronic devices to replace solder.

Selecting the most suitable formulation is dependent on the size/type of components, application conditions, curing & processing requirements, and dispensing needs. Common application methods include screen printing and syringe/needle dispensing.

These products offer no tailing, limited flow after component placement, low moisture absorption, wide operating temperature range, excellent resistance to mechanical shocks and vibrations, and high physical strength properties.
