我厂生产某产品以来,一直存在片状电位计汇流条的质量问题,以致成为生产中的关键;其问题主要是当产品在定期试验时发生断电和接触不良及在定期试验以后发现汇流条划伤和磨损等,由此使产品定期失效。为了解决这一重大质量问题,我们在党支部的领导下组织了三结合攻关小组,作了大量的试验工作,按照毛主席教导的“实践——认识——实践”的观点进行了反复试验,对导电部分进行了多层电镀——镀银、镀镍、镀铬、镀金、镀金锑的试验。但经过多次的试验,性能总是达不到要求,不是导电不良就是磨损太快。后来我们参阅了有 Our factory has been producing a product, there has been the quality of the chip potentiometer busbar, resulting in the production of the key; the problem is mainly when the product in the regular test of power failure and poor contact and in the regular test found after the bus bar Scratches and abrasions, etc., thereby causing the product to fail regularly. In order to solve this major quality issue, we organized a three-pronged key task force under the leadership of the party branch, did a great deal of experimental work, carried out trial and error according to Chairman Mao’s “Practice-Awareness-Practice” point of view, The conductive part of the multi-layer plating - silver, nickel, chrome, gold, gold-plated antimony test. However, after many tests, the performance will always fail to meet the requirements, either the poor conductivity or the wear too fast. Later we see there
