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.

Material Aging Test-UV Weathering Test Chamber 1.What is UV aging? UV aging chambers use fluorescent ultraviolet lamp as light source to simulate UV radiation and condensation in natural sunlight, and to carry out accelerated weather resistance test in order to obtain the result of weather resistance of the material. UV aging detection is widely used in non-metallic materials, organic materials (such as coatings, paints, rubber, plastics and their products) under the change of sunlight, humidity, temperature, condensation and other climatic conditions to test the aging degree and situation of related products and materials. 2.Why we should do UV aging test? When the product is placed in the ambient environment, there will be different problems taken place, such as appearance changes, including cracking, speckle, powdering or color change, and even performance degradation,which may be due to the loss of components in the resin resulting in chemical bonds changes inside the molecular structure, this is mainly caused by sunlight, industrial exclusion of waste gas, bacteria and so on. The aging performance of the product directly affects the lifespan of the product, so aging test become significant,non-metallic materials, organic materials (such as paints, paints, rubber, plastics and their products) are subject to changes in sunlight, humidity, temperature, condensation and other climatic conditions to test the degree and condition of aging of related products and materials. The natural aging test is to put the plastic specimen under the sun exposure, and it is directly under the natural climate environment,to test the material performance under various factors such as light, heat energy, atmospheric humidity, oxygen and ozone, industrial pollution and the like, the most harsh climate condition should be selected,or near the actual application area of the material, the test site shall be open and flat, no obstacle to affect the test results,the specimen holder shall be facing the equator and at an angle of 45 ° from the ground. When the main performance index of the specimen has been reduced, the test s/b terminated when it achieve the minimum allowable use value . in most case,the test is terminated when the product primary performance index falls to 50% of the initial value. The natural aging process is a very slow process, and there is a great difference in different geographical conditions, which brings difficulties to evaluate the aging resistance of the product. It is an attempt to make an evaluation of the aging performance of the plastic in a shorter time,that is accelerated aging test. The accelerated aging test can be used to simulate the human light source of the fluorescent lamp, including the carbon arc lamp, the xenon arc lamp and the fluorescent ultraviolet lamp, and the artificial light sources can generate more light than the natural sunlight on the ground. When these artificial light sources are used, it is also common to use the combination of the condenser to simulate the rain drop, the dew and the like to conduct the aging test on the product.
