The high temperature organic nanocomposite material,also known as synthetic stone,is the latest composite material offered by our company.Developed on the basis of imported material,it works perfectly when in an environment with high temperature,without deformation.Additionally,it has the advantages of little shrinkage and perfect antistatic property.Product with antistatic property based on light characteristic may also be provided at request of customers.
This product is mainly devised for application in the process of SMT mounting and manufacturing of superthin flexible PCB. With unrivalled merits of higher productivity,labor saving,and less rate of defects,it makes a top choice for manufacturers owning SMT mounting production lines. With this product,the workers don't have to fix the flexible PCBs on substrate manually with high temperature tape,as commonly seen when manufacturing with aluminum alloy boards,or imported synthetic stones,which means not only waste of labor,but also high rate of scrap of defects of the product due to the likeliness of protruding or coming off in the solder-reflow cycle. Our synthetic stones provide a solution to all these problems. Covered with a layer of clear or red adhesive,our synthetic stones can resist temperature as high as 300.c
1、As the surface is self-sticking,simply place a flexible PCB on the surface of this product,the PCB board will be fixed readily. It eliminates the necessity of fixing high temperature tape to the substrates manually one by one. 2、The adhesive on the surface of substrate has long serviceability. Where the high temperature adhesive is damaged,simply re-apply an additional layer of adhesive.The synthetic stone itself is also long serviceable. 3、It saves on labor by eliminating the necessity of fixing the boards manually by means of tape. It is really a major breakthrough for SMT flexible PCB mounting production.
Model HY666 is a standard product for general purpose,suitable for working in an environment with high temperature,with the merits of perfect antistatic property and no deformation. Model HY888 is available with two options,antistatic or antistatic based on light characteristic,suitable for infrared ray and optical perceptron.High temperature organic nano material has been tested and proved by many users. Combination of synthetic stone composite board with special high temperature adhesive will play an important role in SMT production in the 21 century. It provides a solution to problems long afflicting many manufacturers.
It will be an only choice for many manufactures desiring for full automation of SMT production with higher productivity, lower labor, manufacturing costs and rate of defects, It makes sense for maximization of the profitability and upgrading of the quality. The material will be made according to the customer's requirement of spec, thickness and size.
SMT supporting board made of synthetic stones has the following functions: 1、Supporting thin substrate or flexible PCB 2、Eliminating the necessity of manual fixing of the flexible PCB by means of tape. 3、Suitable for use in substrate of irregular shape. 4、Thermostable self-sticking surface. 5、Carrying multiple boards to improve the productivity. 6、Saving on labor and manufacturing cost. 7、Avoiding deformation in soldering of substrate. 8、Reducing the rate of defects,and boosting creditability of the manufacturer.
Wave Soldering When in a calescent environment,the perfect thermostable property allows the synthetic stones to give perfect result without deformation.Even when in a harsh environment of temperature 350。C for short time or 280。C continuously,the layers of high temperature nanocomposite material will not separate.
With the following functions,the synthetic stones can improve the wave soldering quality of PCBA: 1、Avoiding contamination of golden finger or contact hole due to contact by hand. 2、Covering the SMT components on the bottom,so that local areas can be soldered by means of standard soldering equipment. 3、Avoiding bending of substrate 4、Standardizing width of production line 5、Using multi-die hole tools to boost productivity 6、Avoiding contamination of substrate surface due to spilled tin
