Systems specially designed to handle liquid dispensed gap fillers and adhesives
There are several considerations to be aware of when you begin to use a liquid dispensed thermal interface material. First and foremost, is choosing the correct product for your application and process. With hundreds of options available with different polymers, filler packages and cure schedules, it’s important to work with a company that can help narrow down the options and help focus the research.
The second consideration, but equally as important if not critical, is choosing the right dispensing equipment supplier. Whenever a liquid dispensed material is introduced into a production environment, there will be a learning curve. Thermally conductive mediums are no exception. The high loading of ceramic fillers creates a material which can behave like sandpaper during dispensing. This abrasion can cause premature wear on many aspects of the dispensing equipment. Often times, overpressurization is used to get these highly filled products moving through the system. This can often result in damage to containers, polymer and filler separation, and caking of the material throughout the dispensing system. It is important that a production company aligns themselves with a dispensing equipment manufacturer who is well versed in thermally conductive liquid dispensed materials, to assist in avoiding pitfalls.
The benefits of liquid dispensed Thermal Interface Materials (TIM)
- Highly automated and repeatable
- Excellent conformability
- Optimized material usage
- Logistics simplification
- Low assembly stress
- Single solution for multiple applications
System configurations for TIM dispensing comes in a variety of different forms. Your method of placement can be as simple as a hand-held unit, semi-automated or entry-level, up to large complex automation equipment. R-tek has experience working with many customers to assist them in starting and scaling up their automated process. Selecting your material and matching it with the correct automated equipment is an integral part of a successful solution.
