The KRT PCB surface cleaning machine stands as an exceptional solution for effectively cleansing printed circuit boards, ensuring optimal cleanliness for intricate electronic components. The machine feature soft brush (18 yo 30 um in diameter) and convulsions system to remove foreign bodies. Various board transport options help meet demanding different dimensions PCB boards requirements.The test outcomes indicated that subsequent to the implementation of the vacuum cleaning apparatus, there was a reduction of 12% in the proportion of internal short circuits attributed to copper residue. The vacuum cleaning machine captured a significant quantity of foreign materials, encompassing black foreign particulates as well as copper fragments. The effective capture contributed to a substantial reduction in internal short-circuit occurrences
