二、技术、质量验收规范: 按照上述“二、3节”标准,结合每个用户厂整机的实际要求,说明书应具体明确各自的技术、质量验收规范。下面分别对基材和工艺进行叙述,以作参考。 1、基材。用户一般只对成品板质量提出具体要求,而把对原材料质量的具体要求留给生产厂去处理。这实际上是不全面的,从某种程度上说,成品板的优质首先取决于原基板的优质。所以用户对生产厂所使用的板材提出自己的技术要求是合乎情理的。 (1)外观要求。基板应没有灰尘、污点、腐蚀物和指印,没有划伤痕迹。应该看不出有裂纹、斑点、龟裂、分层、晕圈或编织的网纹暴露。在非
Second, technology, quality acceptance norms: In accordance with the above “two or three” standard, combined with the actual requirements of each user plant 整机, manual should be specific and clear their own technical, quality acceptance norms. The following description of the substrate and process, for reference. 1, the substrate. Users generally only on the quality of finished board made specific requirements, and to the specific requirements of the quality of raw materials left to the manufacturer to deal with. This is actually not comprehensive, to some extent, the quality of finished products first depends on the quality of the original substrate. Therefore, it is reasonable for the user to put forward his own technical requirements on the sheet used in the production plant. (1) appearance requirements. Substrate should be free of dust, stains, corrosion and fingerprints, no scratches. There should be no cracks, spots, cracks, delamination, halo or weavers exposed. In Africa
