关于我们

  泉州市依科达半导体致冷科技有限公司,坐落于泉州经济技术开发区孵化基地科技园区。泉州市地处东南沿海,自然条件优越,是我国知名历史名城、丝绸之路起点,风景秀丽、气候宜人、经济繁荣、海陆空交通发达,公共设施完善。改革开放之后,泉州市的电子、轻工、机械、陶瓷、茶叶等各行业都得到飞速发展。


  泉州从上世纪九十年代中期,引进半导体致冷技术,开始生产半导体致冷器件,在行业老一辈专家阮秀沧先生的指导下,产品制造工艺和生产技术不断得到优化,所生产致冷器件的性能和质量都处于国内先进行列。产品畅销国内,并远销欧美、日、韩等国家。产品的技术参数和质量得到国内外用户的认可及肯定。


  长期生产半导体致冷器件的经历,为泉州市培养、造就了一大批专业人才。我司组织专业优良技术人员和技术骨干,在阮秀沧先生带领下开展技术攻关,对原有的生产技术和工艺进一步探讨和研究、试验,历经艰苦努力,对各个关键工序都进行了改进(晶棒制造工艺、排模工艺、焊接工艺、表面处理工艺等)达到预期效果,取得圆满成功。特别是我们依靠自身努力,成功研制出N型晶棒压制新工艺,成为国内首家同时拥有P型和N型晶棒压制工艺的厂家。


  N型压制晶棒与当今国内普遍采用的N型拉晶晶棒相比,其优点是晶棒机械强度较高,可用来加工厚度更薄、截面积更小的晶粒。与此同时,我们在国内首家成功研制了一种新型专用焊机,用以对上、下基板与晶粒同时进行焊接,这种新工艺可在很大程度上降低、消除器件在焊接过程中所产生的热应力,防止基板在焊接过程中出现热变形和避免晶粒在热应力作用下产生裂纹、破碎,从而大大提高了产品的可靠性和使用寿命。


  N型压制晶棒工艺和新型专用焊机研制成功并投入使用,所生产的产品,其温差、可靠性等主要技术参数都达到俄罗斯进口同类产品的水平。表明我司技术水平在原来基础上又更上了一个新台阶。为企业技术进步、产品升级换代奠定了坚实基础。今后我司将进一步发挥自身的技术长处,开发生产各种性能更好、质量更高、使用范围更广的产品,以满足各行各业,如军工、电讯、交通、电脑、医疗、红外、激光等领域所需的产品。为提高用户产品的技术水平和质量作出不懈努力。


  阮秀沧:高级工程师,现任我司总工程师。从上世纪七十年代开始,便参与半导体致冷器件技术的研制工作至今,长期的工作历练,积累了丰富的工作经验和理论知识,对半导体致冷器件研究制造有较高造诣。参与制订我国第一部半导体致冷器件部颁标准,曾担任中国电子元件行业协会敏感元器件与传感器分会第五届理事会理事。并长期担任半导体致冷器件中外合资企业技术高管,为业内知名人士。现带领我司技术研制小组人员,开展技术攻关,取得了丰硕成果。


      Quanzhou yikeda semiconductor refrigeration technology co., LTD. Is located in the technology park of the incubator base of quanzhou economic and technological development zone. Located in the southeast coastal area, quanzhou enjoys favorable natural conditions. It is a famous historical city in China and the starting point of the silk road. It has beautiful scenery, pleasant climate, prosperous economy, developed sea, land and air transportation and perfect public facilities. After the reform and opening up, quanzhou city's electronics, light industry, machinery, ceramics, tea and other industries have been rapidly developed.

      In the mid-1990s, quanzhou introduced semiconductor refrigeration technology and began to produce semiconductor refrigerator parts. Under the guidance of ruan xiucang, an expert of the older generation in the industry, the product manufacturing process and production technology were continuously optimized, and the performance and quality of the refrigerator parts produced by the company were in the advanced ranks in China. Products sell well in China, and exported to Europe, the United States, Japan, Korea and other countries. The technical parameters and quality of the products are recognized and affirmed by users at home and abroad.

      Long - term production of semiconductor refrigerator parts experience, for quanzhou training, training a large number of professionals. We organize excellent professional and technical personnel and technical backbone, led by Mr RuanXiu surging to conduct technical research, the production technology and process of the original further discussion and research, test, through hard work, for each key process is improved (crystal rods manufacturing process, molding process, welding process, surface treatment, etc.) to achieve the desired effect, a complete success. In particular, we have successfully developed a new technology to press n-type crystal rod by our own efforts, and become the first domestic manufacturer to have both P type and N type crystal rod press technology.



Compared with the n-shaped crystal rod commonly used in China today, the n-shaped crystal rod has the advantage of higher mechanical strength, which can be used to process grains with thinner thickness and smaller cross-section area. At the same time, we in the domestic first successfully developed a new type of special welding machine, used for upper and lower substrates and grain for welding at the same time, this new technique can largely reduce and eliminate the device thermal stress produced in welding process, to prevent the occurrence of hot deformation substrate in the welding process and avoid grain under the action of thermal stress crack, broken, thus greatly improving the product's reliability and service life.



The n-type pressed rod technology and the new special welding machine have been successfully developed and put into use. The main technical parameters of the products produced, such as temperature difference and reliability, have reached the level of similar products imported from Russia. It shows that our technical level is a new step on the original basis. The company has laid a solid foundation for technological progress and product upgrading. In the future, we will further develop and produce all kinds of products with better performance, higher quality and wider range of use, so as to meet the requirements of various industries, such as military industry, telecommunications, transportation, computer, medical treatment, infrared, laser and other fields. Make unremitting efforts to improve the technical level and quality of user products.



Ruan xiucang: senior engineer, the current chief engineer of our company. Since the 1970s, I have been involved in the research and development of semiconductor refrigerator technology till now. With long working experience, I have accumulated rich working experience and theoretical knowledge, and I am highly accomplished in the research and manufacture of semiconductor refrigerator parts. Participated in the formulation of the standards for the first semiconductor refrigerator, and served as the fifth council member of the sensitive components and sensors branch of China electronic components industry association. And long - term as a semiconductor refrigerator parts joint venture technology executives, well-known industry figures. Now I led the technical development team to carry out technical research, and achieved fruitful results.
