In the operation of SMT mounter, the process and integrity of the nozzle of the mounter will have a significant impact on the performance of the machine. As one of the important components of the SMT machine, it is necessary for us to carry out daily maintenance and upkeep of the SMT nozzle. To ensure that the suction nozzle of the SMT machine is intact before operation, how should we do a good job of maintaining the suction nozzle of the SMT machine during normal use? KINGSUN technical team analysis operation has the following main points: 1.Wipe the surface of the SMT nozzle with a dust-free cloth. 2.The small aperture nozzle can be passed through with a thin steel wire and then blown with an air gun. 3.The surface of the nozzle should not be soaked with corrosive solution such as alcohol, as this may cause the surface to fall off. 4.HOLDER should use a cotton swab to wipe the cavity and not damage the filter screen. 5.Regular addition of special grease to HOLDER claws. 6.According to production, it is best to regularly maintain and do other maintenance regularly. (* Suitable for Yamaha SMT machine nozzles , JUKI SMT machine nozzles, Samsung SMT machine nozzles, Panasonic SMT machine nozzles, Fuji SMT machine nozzles, Siemens SMT machine nozzles etc.) Regarding the SMT machine nozzle daily maintenance operation instructions, KINGSUN share with you here , hoping to be helpful to you.

In this study, the modification of an epoxy matrix with different amounts of cube-like and rod-like CaCO3 nanoparticles was investigated. The effects of variations in the morphology of CaCO3 on the mechanical properties and thermal stability of the CaCO3/epoxy composites were studied. The rod-like CaCO3/epoxy composites (EP-rod) showed a higher degradation temperature (4.5 _C) than neat epoxy. The results showed that the mechanical properties, such as the flexural strength, flexural modulus, and fracture toughness of the epoxy composites with CaCO3 were enhanced by the addition of cube-like and rod-like CaCO3 nanoparticles. Moreover, the mechanical properties of the composites were enhanced by increasing the amount of CaCO3 added but decreased when the filler content reached 2%. The fracture toughness Kic and fracture energy release rate Gic of cube-like and rod-like CaCO3/epoxy composites (0.85/0.74 MPa m1/2 and 318.7/229.5 J m
