Material Notes:
CircuitSAFâ„¢ MA-420 is an epoxy surface mount adhesive that cures rapidly at elevated temperatures and has been designed for use in high speed printed circuit board assembly for the attachment of surface mount components. This product is unique in that it can be used for both high speed dispensing and rapid printing without sacrificing any performance in either application. The high shear thinning and excellent viscosity recovery makes the material an excellent choice for high speed SMT applications. CircuitSAFâ„¢ MA-420 has been successfully used in high speed placement systems with integrated dispense heads. A list of equipment and the corresponding packaging can be found in the CircuitSAFâ„¢ MA-420 Brochure. CircuitSAFâ„¢ MA-420 also shows superior performance in non-contact dispense systems such as the Asymtek Dispense JetTM. The superior dot profile and high dot aspect ratio make it ideal for rapid printing. CircuitSAFâ„¢ MA-420 is fully compatible with the DEK ProFlow DirEKt ImagingTM system and is available in DEK ProFlowTM Cassettes.All information provided by Lord.
