Problems solved by technology

New materials represented by LTCC, aluminum nitride, aluminum silicon, aluminum silicon carbide, etc. are being more and more widely used in advanced radar electronic components. These new materials each have their own new characteristics: LTCC and aluminum nitride themselves belong to Porous material, rough surface is easy to absorb flux, and due to the brittleness of ceramics and other reasons, it cannot be simply cleaned with high-power ultrasonic vibration cleaning equipment
Aluminum-silicon, aluminum-silicon carbide, etc. are used as the box material, and the surface coating is difficult to achieve high flatness, and it is not easy to polish, and the probability of residual flux...

Abstract

The invention provides a water-based environment-friendly cleaning method of soldering flux generated in the welding process of a radar electronic module. The cleaned object is the radar electronic module of which a ceramic substrate and a related connector are installed and welded. A cleaning system comprises a cleaning clamp, a moving mechanism, a soaking ultrasonic flow spraying cleaning mechanism, a reverse spraying rinsing mechanism, a solvent dehydration bubbling mechanism, a baking mechanism and a feeding and discharging table. According to the operation steps, 1, the radar electronic module to be cleaned is clamped; 2, soaking ultrasonic flow spraying cleaning is carried out, and a multi-component composite water-based cleaning solution is adopted as a soaking cleaning solution; 3, pure water is used for carrying out reverse spraying rinsing; 4, solvent dehydration bubbling treatment is carried out, and dehydration solvent is ethyl alcohol with concentration being over 95% or other alcohol solutions easy to volatilize; and 5, hot wind baking is carried out.

Description

technical field [0001] The invention belongs to the field of automatic radar electronic batch production, and in particular relates to a method for cleaning flux produced in the welding process of radar electronic components. Background technique [0002] With the development trend of advanced radar electronic systems moving toward arrayization, the system side has begun to demand thousands of single systems for radar electronic components. In the face of huge demand for components and system requirements for component consistency, automated production has become the only way to cope. New materials represented by LTCC, aluminum nitride, aluminum silicon, aluminum silicon carbide, etc. are being more and more widely used in advanced radar electronic components. These new materials each have their own new characteristics: LTCC and aluminum nitride themselves belong to Porous material, rough surface is easy to absorb flux, and due to the brittleness of ceramics and other reaso...
