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.
