What are the job requirements of IQC

A. IQC knowledge of incoming quality control, also known as IQC (that is, the abbreviation of Incoming Quality Control) 1.IQC responsibilities? ★ IQC responsibilities: unqualified handling of incoming inspection supplier counseling and its assessment to follow up the use of incoming materials ★ IQC notes are: to understand the customer and the next process of product requirements as far as possible to provide suppliers with information on the product (including the actual accessories), to ensure that exhaustive and timely detection of the problem, notify the next process and the supplier to analyze the supply of quality conditions. 2.IQC inspection process? Check the incoming material acceptance form → according to the sample or recognition of the test electrical and appearance → test → fill in the IQC report → stick the test results of the label card. 3.IQC inspection methods are? Full inspection: small quantities, high unit price sampling: large quantities, or recurring materials exemption: small quantities, low unit price, or general subsidies or recognized as exempt from inspection of manufacturers or limitations of the material. 4.IQC OK stickers in spring, summer, autumn and winter, respectively, with what color? Green in spring, blue in summer, orange in fall, white in winter.5. How many kinds of stickers are used to mark the inspection results after IQC inspection of incoming materials? ***There are three kinds of labels: qualified, special, rejected. 6. What are the conditions for issuing a supplier's abnormal contact report for incoming material inspection? When a supplier of the same kind of incoming materials for two consecutive batches failed, to be issued to the supplier to issue supplier quality abnormalities in contact with the single supplier. IQC specific inspection process preparation: A. Understand the product's usefulness, the use of the environment, how to match with **** it with the product B. Relevant inspection and testing standards, tools, the actual allocation of samples to test the content: A. Confirmation of the product specifications, quantities, packaging B. Dimensions: Measurement of the key dimensions, C = 0, according to the relevant standards to determine the appearance of the: ¤ Inspection conditions: A. Distance: 300 ± 50MMB. 50MMB. Light: 1M under 60W fluorescent lamp (for reference) C. Angle: 90 ° or 45 ° 4. Structure, function: A. Trial assembly: new materials, new products or change the specifications of the product must be confirmed B. Relevant tests, C = 0 according to the relevant standards to judge ¤ product surface grading method: level surface: the customer's normal residency in the right to use the use of the products in the product or to see the purchase of the underside of the product. Grade surface: the side of the product that the customer can see in normal use or purchase. Grade surface: the bottom surface of the product which cannot be seen by the customer in normal use. Note: A-level surface appearance requirements of the highest, followed by B-level surface, C-level surface of the lowest ¤ on the appearance of the more vague standards for the determination of methods: find five people to see, do not tell where the bad: 1 if 4 people ah 5 people can not be seen, it was judged as OK; 2 if 4 or 5 people can see, it was judged to be NG; 3 if 2 or 3 people can see, it can be collected after the improvement of the 5. Reliability: vibration experiments drop test sweeping frequency vibration, free Drop, collision experiment wear-resistant experiment adhesion experiment, according to the relevant standards for judgment. 6. life (when required) the use of time or number of times, according to the relevant standards for judgment. 7. safety: (when required) human contact with the material is non-toxic, leakage protection, etc., according to the relevant standards for judgment. 8. marking and recording: marking the product and record the results of the inspection. 9: Batch return, the factory selection, manufacturer selection, special pick 10. Follow-up: Follow-up on the handling of unqualified 11. Sampling Inspection Sampling Inspection related terms: A. Inspection: is one or more characteristics of the product such as measurement, inspection, testing or measurement and compare the results with the specified requirements in order to determine the qualifying conditions of each of the characteristics of the activities carried out. Sampling test: is from a batch of products randomly selected part of the activities carried out. B. "a batch of products: known as the overall, the overall content of the expressed in N: to be drawn out of the test of the" this part of the product "known as the sample, expressed in n. C. Defects: units of the product does not meet the expected requirements for the use of the product or does not meet the reasonable expectations. D. Failure: the unit product of any one quality characteristic does not meet the specified requirements. E. Failed product: one or more failed unit product, known as failed product. F. Process average: a series of delivery batch of the initial inspection of the percentage of defective products. H. AQL: acceptable process of successive batches of the upper limit of the level of Yun, used to describe the process of averaging an important indicator, it is regarded as ¤ as the average of the process. It is regarded as the dividing line between acceptable and unacceptable process averages. Sampling and inspection: destructive inspection and acceptance: product possibility test: product life test: material fatigue test: strength test of parts, etc. The product quantity is large and the quality requirement is not high: screws, nuts, pins, etc.. Measurement object is process material; steel and iron assay. Wish to save inspection costs. Inspection of more items ¤ Sampling conditions: the production process is stable distribution of nonconforming products is uniform ¤ Failure of the classification: Class A failure: unit product of very important characteristics do not comply with the provisions of the unit product, or unit product of the quality characteristics of the very strict failure to comply with the provisions of the Class B failure: unit product of the important characteristics of the unit product does not comply with the provisions of the unit product or unit product of the quality characteristics of the serious failure to comply with the provisions of the Class C failure: the general characteristics of the unit product does not meet the requirements, or unit products Class C failure: the general characteristics of the unit product does not meet the requirements, or the quality characteristics of the unit product slightly does not meet the requirements ¤ the classification of nonconforming products: Class A failure: there is one or more than one Class A failure, there may also be Class B failure and Class C failure of the unit product Class B failure: there is one or more than one Class B failure, there may also be a Class C failure, but there is no Class A failure of the unit product. class C failure: there is one or more than one Class C failure, there may be a Class C failure, but there is no Class C failure. or more than one C failed, but there is no B failed, there is no A failed unit of the product. ¤ Sampling and testing methods: A. A sampling: only one sample from the batch, after testing the sample, you can make a judgment of the batch qualified or not. B. Secondary sampling: from the batch of up to two samples of the sampling, you can make a judgment of the batch qualified or not. ¤ AQL value of the determination of methods: according to the quality of customer requirements to determine the process average to determine the category of failure to determine the number of items to determine the consideration of the test to determine the number of negotiation with the supplier to determine the other methods of determination
