User’s dilemma: Case
To both our company and our clients · · · double challenges
Our company manufactures and sells a wide variety of adhesives.
In conductive adhesives, one of our main products, the mixing and dispersion of air bubbles is an extremely critical factor. Because a metal filler, such as silver, is used with various kinds of resins, precipitation and separation of the filler are likely to occur. This has posed a serious problem in the efficiency improvement of the manufacturing process, during which sufficient dispersibility should be maintained.
In addition, it has been necessary for our clients themselves to redisperse the metal filler and establish the appropriate conditions for the conductive adhesives immediately before use. We have been searching for a solution to this problem. For example, some quartz resonator manufacturers perform manual mixing when using our conductive adhesives, but this has resulted in the following problems: (1) The conductivity of the adhesive joint between the quartz and the terminal fluctuates considerably. (2) Air bubbles taken into the joint cause blank beating. (3) Clogging of needles due to insufficient dispersion causes defective products, leading to yield deterioration.
We have been looking for ways to solve these problems related to conductive adhesives, which arise during the manufacturing process and during actual use by our clients.
