Product Introduction to Die Bonder Suction Nozzle Cap: The LED suction nozzle cap is an adapter that connects the suction nozzle to the vacuum system in automatic die bonding machines. There are two specifications of suction nozzle caps in ASM automatic die bonding and mounting machines. The suction nozzle cap used in early-produced machines such as the 809 series has three openings: one for the vacuum port, one for the MISS DIE detection lamp mounting port, and one for the suction nozzle mounting port. Recent die bonding machines mostly use two-hole suction nozzle caps, with one end for the vacuum port and the other end for the suction nozzle mounting hole. Crystal leakage detection relies on vacuum induction. Common machine models include: AD809, AD50, AD892, AD896, AD8930, AD898, AD820, AD830, AD860, AD862, and other domestically produced die bonding equipment from companies such as Jiasi Special Electromechanical, Xinmeihua, Weikong Automation, Cuitao Automation, Youguang Electromechanical, Dazhu Laser, Zongke, Xingkong Electronics, and Xinyichang Electromechanical.
