Chip-On-Board (COB) Encapsulating – Glob Top and Dam & Fill/Frame & Fill Adhesives

Glob Top and Dam and Fill/Frame and Fill encapsulation provides protection for individual electronic components attached to PCB’s and FPC’s. Encapsulated components are shielded from environmental stresses, contamination, and mechanical vibration. Tangent’s encapsulating materials serve to neutralize dissimilar Coefficient of Thermal Expansion (CTE) values between the component and board.

Glob Top and Dam & Fill/Frame & Fill encapsulation provides protection for individual electronic components attached to PCB’s and FPC’s. Encapsulated components, (i.e. Flip-Chips, semiconductor die chips, delicate lead wires, etc.), are shielded from environmental stresses, contamination, and mechanical vibration. Tangent’s encapsulating materials serve to neutralize dissimilar Coefficient of Thermal Expansion (CTE) values between the component and board.

In addition, these materials improve individual component insulation, minimizing current loss.

Glob Top and Dam & Fill/Frame & Fill processes are integrated into automated assembly lines using programmable, robotic dispensing equipment. The encapsulating materials are deposited directly on the components and boards in precise, repeatable patterns.

Panacol-USA produces single component, light curable encapsulants with performance properties that are ideal for high volume production lines. The materials are highly resistant to contaminants, cure with minimal shrinkage, and remain extremely flexible to minimize risk of damage to fine wire leads and connections.

Tangent also offers encapsulants from Panacol-Elosol. Panacol-Elosol GmbH is part of the Honle Group headquartered in Germany, and has been formulating and manufacturing adhesives for over 30 years. Tangent is the exclusive distributor of Panacol’s products in the Americas. Light curable acrylates from Panacol are identified under the Vitralit® brand. Room temperature and thermal curing epoxies carry the Structalit® label. Structalit® epoxies are available as single or two component systems.

Please contact Tangent to confirm your product selection and to secure additional application assistance, including samples and process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include development of adhesive specifically tailored to the complexity of your application.
