Nowadays, the government and the private enterprises invest lots of money and energy dedicating to the automatization projects. Since July in 1990, the automatization group of the Executive Yuan of the Republic of China cooperates with the related government organization dedicating to the R&D of the Industrial 10-years automatization project. And until 1998, the percentage of automatic factory elevates from 31% to 67.6%. From the above information, it indicates that the automatization is getting more and more important in modern indutry. We specialized in the manufacture of the printing circuit board since 1990. In 1994, we found that in the producing process of the computer related motherboard and the slot card. The cleaning process Flux needs to be connected to the production line. Therefore, we dedicate to the research and development of the cleaning equipments. (PCB continuous wash machine). And founded the Yang Fa Enterprise Co., Ltd. We are the OBM factory in Taiwan. We often take part in the trade show. Occasionally, we got the related BGA product documents in the show. We improve the PCB continuous wash machine and create the BGA continuous wash machine. The above improved invention is not only light, energy time saving andmore efficient than the former product.
