Description

Technical Field

[0001] The invention relates to the field of electronic device cleaning, in particular to a multifunctional cleaning machine and a SIP product cleaning method. Background Art

[0002] Existing SIP products (system-in-package products) need to clean the flux left after the substrate stacking welding during production to ensure the reliability of SIP products. However, existing cleaning equipment and cleaning methods are difficult to effectively clean the flux left by SIP products while protecting SIP products. The specific situations are:

[0003] 1. Existing SIP products are produced by combining micro-assembly process with flip-chip process. In this way, SIP products have both micro-assembly process characteristics such as gold wire bonding and bare chip bonding, and flip-chip process characteristics such as solder balls and copper pillars. This makes it impossible to use ultrasonic cleaning equipment (such as an ultrasonic cleaning machine for electronic components disclosed in Chinese patent CN202310595829.X) and ultrasonic cleaning process to clean SIP products, because ultrasonic cleaning can easily damage SIP products, causing damage or abnormality of SIP. In particular, ultrasonic cleaning is strictly prohibited for SIP products used in the aviation field.

[0004] 2. To ensure the airtightness requirements of SIP products, when producing SIP products, it is necessary to first use gold-tin to weld the frame and the package substrate, and then stack the substrates in the frame. Since the gap between the substrate and the frame is only 0.4-0.6mm, the gap between the stacked substrates is about 0.3mm. The existing spray cleaning equipment (such as a PCBA offline cleaning machine disclosed in Chinese patent CN201610274942.8) has low pressure and flow, and it is difficult to pass the cleaning liquid through the above gap to the solder flux on the solder ball bumps of the SIP product. At the same time, due to the obstruction of the frame, As a result, the rinsing liquid cannot be discharged smoothly; therefore, the existing spray cleaning equipment cannot effectively clean the flux retained by the SIP product; and the existing vapor phase cleaning equipment (such as the fully automatic vapor phase cleaning equipment disclosed in Chinese patent CN202222819171.X) although the chemical cleaning agent used has strong dissolving ability and small surface tension, so that the chemical cleaning agent can act on the solder flux on the solder ball bumps through the gap between the packaging substrate and the frame and the gap between the substrates, but because the amount of chemical cleaning agent entering the above gaps is small and there is no mechanical flushing effect, the cleaning effect on the solder flux is not ideal.

[0005] In view of the above problems, it is necessary to study a multifunctional cleaning machine and a SIP product cleaning method, which can effectively clean the flux retained by the SIP product while protecting the SIP product. Summary of the invention
