Webinar: gap filler vs gap pad, which solution is best for your needs?

Mascherpa has organized, together with MacDermid Alpha and the Electrolube lines, a new technical webinar dedicated to thermal management in electronic design, focusing on the comparison and choice between gap filler and gap pad and the criteria guiding that choice.

The webinar, featuring Enrico Quagliato, Head of the Electronics Division at Mascherpa, and Lorenzo Sala, Technical Business Development Manager Europe at MacDermid Alpha, will take place on November 18 from 11:00 AM to 12:00 PM (CET). It will analyze how the choice of thermal interface material affects thermal performance, processability, and overall application costs.

Why talk about gap fillers and gap pads in electronic devices

Heat management in electronic devices requires evaluating different design and production needs, which influence the choice of material to be inserted between components and heatsinks:

• assembly thicknesses and tolerances;
• contact pressure;
• mechanical stress on components;
• electrical insulation requirements;
• application methods and production volumes.

In this context, the thermal interface material represents a design variable that affects heat transfer between coupled surfaces.

Gap fillers and gap pads have different characteristics in terms of:

• wettability, conformability, and thermal resistance of the interface;
• manual application and process automation;
• electrical insulation, thicknesses, and workability;
• material waste and overall application costs.

However, neither solution is automatically the correct choice for every device.

Every application presents different thermal requirements, assembly constraints, and production conditions that must be carefully evaluated during the design phase. The choice of material requires considering:

• contact with surfaces and necessary pressure;
• electrical insulation needs;
• possibility of removing and replacing the material after assembly;
• application times and equipment investments.

For this reason, it is essential to understand when to use a gap filler or a gap pad, what features they offer, and what aspects must be considered before their application.

What topics the webinar on gap fillers and gap pads will cover

The webinar will provide a technical overview of the comparison between gap filler and gap pad in electronic design.

During the webinar, Lorenzo Sala and Enrico Quagliato will practically analyze the choice of thermal interface materials:

• Differences between gap pads, two-component gap fillers, and pre-cured gels;
• How pre-cured gels differ from thermal pastes;
• Impact of wettability, pressure, and conformability on the thermal resistance of the interface;
• Electrical insulation, thicknesses, workability, and material shelf life;
• Manual application and automated dispensing: times, part number management, and waste;
• How to choose the material based on the actual application, with two real-world cases comparing inverters and charging stations.

A technical deep dive that goes beyond the product and into design logic.

The goal will be to understand how to choose the material based on the actual application, assembly requirements, and the production process. A technical approach that compares the characteristics of different solutions, also considering how volumes, labor, and equipment investments impact the economic evaluation.

Who the webinar on gap fillers and gap pads is for

The webinar is designed for electronic designers, PCB engineers, R&D managers, quality and production managers, process technicians, and companies that develop or assemble electronic devices.

It is particularly suitable for those operating in contexts where thermal management, electrical insulation, and assembly methods represent critical aspects in material selection and production process definition.

Why take part in the webinar on gap fillers and gap pads

Participating in the webinar dedicated to the comparison between gap filler and gap pad means having the opportunity to:

• understand the role of the thermal interface in electronic design;
• avoid choices inconsistent with application and production needs;
• evaluate stresses on components and electrical insulation requirements;
• compare application costs, investments, and material waste;
• discuss real-world application approaches.

How to participate in the webinar?

By participating in this webinar, you will have the chance to explore the role of gap fillers and gap pads in electronic systems and understand how material choice can directly influence thermal performance, processability, and overall application costs.

It will be a useful time to analyze aspects related to pressure, conformability, electrical insulation, and reworkability, discussing concrete design and production criteria, including two economic comparisons regarding inverters and charging stations.
