Embodiment
[0034] A coating process for radio frequency circuits, comprising the steps of:
[0035] S1: PCB protective agent is selected as the coating material;
[0036] S2: Clean up the radio frequency circuit;
[0037] S3: drying the radio frequency circuit and cooling it to normal temperature;
[0038] S4: Coating the RF circuit multiple times: Use a three-proof coating device to coat the RF circuit with a PCB protective agent. After coating, put it in a high-temperature oven at 80°C to 90°C and bake it for 0.5 to 1 hour. Cool to room temperature and repeat this process several times.
[0039] Further, a coating process for radio frequency circuits, the PCB protectant in S1 and S4 is RH-35 type PCB protectant.
[0040] Further, a coating process for radio frequency circuits, the S2 is specifically cleaning iron filings, welding slag, and dirt on the surface of radio frequency circuits with alcohol.
[0041] Further, in a coating process for radio frequency circuits, the multiple ...
