Radio frequency interference (RFI) and electromagnetic interference (EMI) can be caused by improper shielding and contacts in devices and electronics. They can cause unwanted signals and noise to interfere with the intended signals. RFI and EMI are prevented or reduced with proper contacts, fingerstock, and gaskets.

Contacts are used to conduct signals between different components or devices. The contact material needs to have high conductivity and good corrosion resistance. It is also essential that contact pieces are highly repeatable in order to ensure reliable performance over time. In addition, if the contact pieces have any chatter, then it is important to make sure that contact pieces are properly spaced in order to reduce friction between them. All of these factors will help to reduce any RFI or EMI that may be caused by improper contacts.

Fingerstock is a type of insulation that is used in electronic components and devices. It is used to reduce the likelihood of electrical shorts. It is typically made out of metal and rubber, and it is designed to be flexible so that it can fit snugly around most surfaces. Fingerstock will help to reduce unwanted signals and noise from entering the circuit. It also helps to reduce the possibility of static electricity which can cause interference.

Gaskets are used to provide a seal between components. This helps to ensure that no air can leak between them and cause interference. Gaskets are typically made out of rubber or silicone and they are designed to be flexible and durable. Gaskets are essential in cases where components are subject to extreme temperatures or environmental changes which may cause interference due to thermal expansion or contraction. The use of gaskets is also important when components need to be electrically isolated from each other in order to prevent RFI and EMI.

RFI and EMI can be irritating and costly to fix. They can be caused by improper contacts, fingerstock, and gaskets. Properly designed and installed contact pieces, fingerstock and gaskets are essential in order to reduce the occurrence of interference. In addition, proper installation is important to ensure that the components are working properly. By using quality materials and proper installation, RFI and EMI can be reduced and the performance of the device or equipment can be improved.
