Why does the dome roll up after being attached to the PCB?


In the process of using metal dome adhesive patches, it is important to ensure that they remain flat. However, there are instances where an issue arises: when initially applied to the PCB board, the adhesive patch is flat, but after a period of time, the edges of the patch begin to lift, which can result in dust ingress and poor contact. So, what are the reasons for this problem?

Metal domes have long been favored in electronic products. On the market, some subpar products, although inexpensive, reveal issues such as poor adhesion of the domes. Displacement or detachment frequently occurs after a period of use. These are the outcomes of inadequate inspection during production, resulting in flawed products. Hence, when purchasing membrane switches, it is essential to meticulously select suppliers. Below, we will introduce how to prevent the phenomenon of metal dome lifting.
