| Abstract: | This paper investigates the EBW technique for sealing the box of high-power phase shifter with the cover board.Joint design solved the problem of removing the cover board and then repairing once the circuit.Appropriative welding clamps are designed to control temperature increasing.The maximum temperature is less than 60oC measured with point-thermometer.Special welding procedure of welding one slopt twice to ensured melting deepness and improved joint quality.The sealing performance of the phase shifter is superior than 1.013×10-3 Pa.cm3/s Helium leak rate tested by the Helium mass spectrometer leak detection system.The phase shifters are employed on antenna and feed line system of a radar successfully. |
