Chip off acceptance limits subjected to the product size. Our current Defect limit is based on the IPC-A-610. Some chip off does not impact the product function, see the IPC standard 1 & 2. w T L Marking T ≤10% of the thickness Each surface can only accept W ≤10 % of the width one minor chip off,and more than 3 L ≤10 % of the length chip off problems are not allowed on the same product. Defects usually occur at the corners and edges of the product,There will be a slight defect black and rough, but not exposed copper, and does not affect the product performance and reliability. 3、Crack Production process of cracks appearing in the body is inevitable, some slight crack is caused because the molding, is not oxidized, crack on the product will not affect product performance. We have done a reliability test of crack products, even if cracks is more than 0.13mm also will not affect the electrical properties of the product, crack limits as follows: Products from a slight crack in the baking process due to thermal expansion, and it is not obvious by visual inspection (Must not exceed the blue square area). Cracks on the same side surface are not allowed to exceed 1/2 of the length of the side and the crack width cannot exceed 0.13mm, and only 1 crack is allowed on the same side. Bottom cracks are not allowed to exceed 1/2 of the length (or width) of the corresponding body nor the Non-manufacturability swelling, and the crack width cannot be exceed 0.13mm, and less than 2 cracks are allowed and judged as good products. Visible cracks and non-manufacturability bulging are not allowed on the front side. 4、oxidation(rust) the contains iron composite, although the resin has a protective effect of oxidation,but there will be small amount of product that may occur oxidation, The oxidation area of each surface is allowed to be about 25% (in the case of non-reliability test),it is recommend that customer use this product in humidity controlled environment.The basic steps should be to protect the surface oxidation, including the sealed packages to PCB mount inductors. To avoid the adverse effects caused by oxidation, Oxidation occurs at the surface only allows the internal oxidation is not allowed, oxidized surface will not affect the reliability of the product. Marking 4sides slightly oxidized side: Acceptable Marking Top and bottom slightly oxidized side: Spray printing effect : can be accepted if recognizable Acceptable Visual inspection: Examination with the naked eye, to distinguish from more technical modes of analysis employing tools or apparatus.
