Description

Technical Field

[0001] The utility model relates to the technical field of test boxes, in particular to a microwave circuit board block test box. Background Art

[0002] Microwave integrated circuits work in the microwave and millimeter wave bands. They are integrated on a substrate with microwave passive components, active devices, transmission lines and interconnects. They have certain functions. When testing microwave circuit boards, the microwave circuit boards are placed on testing devices and testing machines, and then the microwave circuit boards are powered on for testing. This test box is used for power-on testing of microwave circuit boards.

[0003] After long-term use of the test box, a large amount of dust and impurities will inevitably accumulate inside the inner cavity. The inner cavity of an ordinary box is purely sealed and cannot automatically discharge dust and impurities. As a result, after long-term measurement of microwave circuit boards, a large amount of impurities are easily accumulated in the box, which is not conducive to the subsequent safe and stable use of the box.
