UV three anti paint will affect the circuit board signal
On whether the UV three anti paint will affect the signal of the circuit board, AVENTK first told you that the result of the case analysis is that the PCB board UV three anti paint itself will not affect the wireless signal of electronic products.
In order to verify the situation, AVENTK took two functional PCB circuit boards of three models from the customer's site for cleaning and dehumidification, and coated the same type and batch of PCB board with UV three-proof paint respectively. After curing, the signal test was conducted, and the result was that the signal of the two models of PCB board was normal, and one signal weakened significantly. This result shows that the three anti paint of PCB board has no direct relationship with the function of signal components.
So why is the signal of some PCB board weak? Here it is necessary to involve the PCB board three anti paint and PCB board's important electrical characteristics dielectric constant. The size of dielectric constant not only affects the propagation speed of the signal, but also affects the characteristic impedance of the signal. Therefore, the dielectric constant test of the PCB board of the above abnormal models and the PCB board coated with three-proof paint found that the local dielectric constant of the circuit board was affected after the coating of three-proof paint, resulting in abnormal signal.
Through the above verification conclusion, AVENTK can tell you that the use of UV three-proof paint to ensure normal signal reception of electronic components, first of all, we should know the dielectric constant of PCB board, choose a more matching PCB board three-proof paint, avoid UV three-proof paint to change the dielectric parameters of the circuit board. On how to select the type, we recommend you to consult AVENTK through online customer service, email, website message, call and other ways to select the type, we will provide you with the overall glue and curing solutions!
