Temperature and humidity test chamber has brought a lot of help to many industrial enterprises, but while it brings convenience to us, we should also take good care of them, otherwise they may be brought into the end-of-life phase ahead of time. The way of maintenance is also very simple. After daily use, the equipment is cleaned regularly, but the cleaning of the test chamber is also very skillful. If the operation is wrong, it may also lead to equipment failure. Let‘s learn how to extend the service life of the temperature and humidity test box together. 1, Pls clean the working room with water after each use, then dry the interior with dry cotton cloth. 2, Pls regularly remove dust from the evaporator inside the equipment, and periodically wipe the equipment to ensure clean and tidy. 3, When doing the test, the sample should be uniformly placed onto sample shelves,and the vent should not be blocked to prevent the influence of the test 4, It is necessary to pay attention to the cleaning of water tanks in peacetime, after the test or when the equipment is not intended to be used for a long time, all the water in the tank should be discharged, otherwise it will lead to the formation of scale inside the tank. The water used in the temperature and humidity test chamber must be pure or distilled water, or long-term use may result in a humidifier or internal pipe clogging. Above are the usual use notice of temperature and humidity test chamber, if customer adhere to the above several points,it is really able to prolong the service life of the equipment.

The biggest problem with designing rigid-flex hybrid PCBs is making sure everything will fold in the right way, while maintaining good flex-circuit stability and lifespan. The next big problem to solve is the conveyance of the design to a fabricator who will clearly understand the design intent and therefore produce exactly what the designer/engineer intended.Rigid-Flex circuit boards require additional cutting and lamination stages, and more exotic materials in manufacturing and therefore the cost of re-spins and failures are very much higher than traditional rigid boards. To reduce the risk and costs associated with rigid-flex design and prototyping, it is desirable to model the flexible parts of the circuit in 3D CAD to ensure correct form and fit. In addition it is necessary to provide absolutely clear documentation for manufacturing to the fabrication and assembly houses.

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.
