Quality is Common Sense.

Quality is nothing but result of care.

It is a value to a person.

Quality may be understood differently by different people. At Jed Sourcing, Our Quality is perceptual and conditional. You may focus on the specification quality of the product according to competitors in the market. We always measure the conformance quality to which the product was produced correctly. We use different techniques and concepts to improve product quality.

We have two different teams.

Quality Assurance team : They prevent the defects.

Quality Control Team : They detects the defects.

On a Whole, we do not compromise on QUALITY. We inspect according to ISO and ASO standards.

  “Trust is good, but control is better"

The old truth has never lost its validity even in today’s commerce of globalization, where quality, precision, customs and ethics are often in short of sufficiency in our distant business dealings. The purchasing of inferior or non-conforming products not only costs enormous economic losses, but can also drastically damage a company's commercial reputation. And unfortunately both buyers and sellers are the victims in such business, because the end customer is always the king.

Therefore inferior products, delayed delivery should be avoided by all means, and the prevention of such a situation has become one of the main objectives. Through meticulous pro-active preparation and control, we can meaningfully minimize the risk of such problems occurring.

Reasonably, we cannot guarantee 100%, but experience has proven that the use of our services minimizes the final risk factor to a very manageable level. And it is a fact that business success is directly dependent on the quality of the goods delivered. Our services will significantly contribute to the upgrading of the quality level of your products, reduce return rates, and increase satisfaction, thus maximizing your profits! It is for this very reason that you should not hesitate to engage in our Quality Control and Assurance Services.

Thanks to the high qualified engineering group, but also customer’s full assistance, JED SOURCING is able to deliver excellent quality inspection service and able to execute tailored quality control program. Our highly professional and experienced team provides independent, efficient and reliable inspection services.

We use well-proven and widely adopted international standard MIL-STD-105E, which is equivalent to ANSI/ASQC Z1.4, ISO 2859, NF06-022, BS6001, DIN40080, GB2828, to inspect a randomly selected number of products. As illustrated below

 

 

As default, we uses general inspection level II, special inspection level S1, Acceptable Quality Level (AQL) 0/2.5/4.0 of critical, major, minor defect.

For example, we have a lot of 12000 units to inspect. According to table 1, "M" is right sample size code for general inspection level II. Therefore in table 2, we pick "315" as M's corresponding sample size. So the allowed maximum number of defective unit is as follows:

Critical Defect 0; Major Defect 14; Minor Defect: 21.

In other words, if the number of critical defective units is more than 0, or major defective units is more than 14, or minor defective units is more than 21, the lot has to be rejected.

How to choice Level I, Level II, or Level III?
Generally, Level II is used for consumer products, but if you think the product is expensive and need check more samples, you can choice Level III, otherwise you can choice Level I.

How to choice AQL 2.5, 4.0 or others?
Generally, 0 for Critical,2.5 for Major, 4.0 for Minor. But if you think the product is expensive and should be checked strictly, you can choice 1.5 or smaller number for Major and Minor, otherwise, you can choice bigger number. The smaller, the stricter.

Quality Inspection Report

Though  JED SOURCING  is executing an extremely professional inspection, but they are commercial inspection which is the purpose of improving the product quality and provide sufficient information for customer’s business decision.

A professional Inspection report will be submitted to customer, containing: general summary, detailed inspection result, and also the suggestions and solutions.

Critical Defect
The "Critical Defect" corresponds to a defect likely to result in unsafe conditions for end-users or specifically requested by customers. The products subjected to Critical Defect should be definitely refused.

Major Defect
The "Major Defect" corresponds to a defect at the function, or to reduce the usability of the unit of product for its intended purpose. Major Defect can be solved by products rework, but acceptance right is generally due to buyer’s decision. ?

Minor Defect
The "Minor Defect" corresponds to a defect that is not likely to reduce the usability of the unit of product for its intended purpose, or is a departure from established standards having little bearing on the effective use or operation of the unit.

Acceptable Quality Level (AQL)
The designed value of defects, expressed as a percentage by the particular sampling procedure and level used will identify what the buyer will normally accept in the majority of cases.
Different AQLs may be designed for different defect classifications such as Critical, Major and Minor.

Unless specified by the client, Debt will adopt the AQL as follows:

 

High valued products

Low valued products

Critical defects

Not allowed

Not allowed

Major defects

AQL 1.0/1.5

AQL 2.5

Minor defects

AQL 2.5/4.0

AQL 4.0

With all the defects detected, JED SOURCING will require the supplier to rework immediately what are acceptable according to the general criteria. For important issues and defects, JED SOURCING  will report immediately to the customers for their instructions.

 

Glossaries


Acceptance Limit (c)
The upper limit on the number of non-conforming items in a sample that would still lead to the acceptance of the entire lot. If the number of non-conforming items in the sample exceeds this number, the entire batch must not be accepted.

Average Outgoing Quality Limit (AOQL)
The highest/worst possible average percent of non-conforming items in the process, after employing some inspection scheme. This measure is usually used in rectifying inspection, where the inspection procedure changes the outgoing rate of non-conforming items in the batch or process, relative to the incoming rate. For example, by removing the non-conforming items that are encountered during inspection. Note that this is only the worse possible average percent of non-conforming items, and therefore there is still a possibility that the percent non-conforming of a single batch will exceed this limit.

Average Run Length (ARL)
The mean (average) of the run length. This is the average number of samples that are taken until an alarm is signaled by the control chart.

Acceptable Quality Level (AQL)
The maximal percent of nonconforming items (or the maximal number of nonconformities per 100 items), which is considered, for inspection purposes, as a satisfying process mean.
The AQL is generally specified by the authority responsible of sampling. Different AQLs may be designated for different types of defects. It is common to use an AQL of 1% for major defects, and 2.5% for minor defects.
Values of AQL that are 10% or less are suitable for percent nonconforming or nonconformities per 100 items. Values of AQL over 10% are only suitable for nonconformities per 100 items.

Alarm Zones
The alarm zones in an ordinary 3-sigma control chart are beyond the upper control limit (3,infinity), and below the lower control limit (-infinity, -3).

  • To specify the alarm zone as the area between the warning limits and control limits, enter a=2, b=3.
  • In a control chart with 0.001 probability control limits (3.09 "sigma") and 0.025 warning limits (2.24 "sigma"), the rule "two consecutive points between the control and warning limits" is given by: k=2, a=2.24, b=3.09.
  • Alarm zones are usually symmetric around the center line. For example: [-3,-2] and [2,3].

Batch/Lot
A batch is a collection of items from which a sample will be drawn, for deciding on its conformance to the acceptance inspection. A batch should include items of the same type, size, etc. and that were produced under the same production conditions and time.
The batch size is the number of items in a lot or a batch.

Clearance Number
The number of consecutive items (or batches, in Skip lot sampling) that must be found conforming, in order to quit the screening phase (100% inspection) when applying continuous sampling.

Inspection Levels for Military Standard 105E (MIL-STD-105E)
The inspection level determines the relation between the batch size and sample size.
Levels I, II, and III are general inspection levels:

  • Level II is designated as normal.
  • Level I requires about half the amount of inspection as level II, and is used when reduced sampling cost are required and a lower level of discrimination (or power) can be tolerated.
  • Level III requires about twice the amount of inspection as level II, and is used when more discrimination (or power) is needed.

The four special inspection levels S-1,S-2,S-3,S-4 use very small samples, and should be employed when small sample sizes are necessary, and when large sampling risks can be tolerated.

Inspection Levels for Military Standard 414 (MIL-STD-414)
The inspection level determines the relation between the batch size and sample size.
Levels I, II, III, IV, V are general inspection levels:

  • Level IV is designated as normal.
  • Level V requires a larger amount of inspection than level IV, and is used when more discrimination (or power) is needed.
  • Levels I,II,III require less inspection than level II, and is used when reduced sampling costs are required, and lower level of discrimination (or power) can be tolerated.

Maximal run length value
The largest number on the horizontal axis, in the run length plot. Or, the largest value of t on the plot for which P(RL=t) is plotted. For example, selecting 500 will give a probability plot of run-lengths in the range 1,2,...,500.

Nonconforming items
The nonconformity of an item is expressed as the percent of nonconforming items. When each item can contain more than one defect, the nonconformity of an item is expressed as the number of non-conformities (defects) per 100 items.

Percent/Proportion Non-Conforming (p)
The percent or proportion of non-conforming items in a batch or in a process. In many cases this is unknown, but it is used to learn about scenarios for different values of p.

Rejection Limit (r)
The smallest number of non-conforming items in a sample that would lead to the rejection of the entire lot. In most cases (besides reduced sampling) this value is equal to the acceptance limit -1.

Run Length
The run length is the number of samples taken until an alarm is signaled by the control chart.

Sample size (n)
The number of items that should be randomly chosen from a batch.

Sampling Fraction f
The proportion of items (or batches, in Skip lot sampling) that are inspected during some phase, when applying continuous sampling. f is between 0 and 1. There are three ways to sample with a fraction of f:

Probability Sampling: Each item/batch is sampled with probability f.

Systematic Sampling: Every 1/f 'the item/batch is sampled.1/f must then be a natural number (e.g., every 3rd item is inspected, when f=1/3).

Block-Random Sampling: From each 1/f consecutive items/batches, one is chosen at random. 1/f must then be a natural number (e.g., in each block of 3 items one is chosen, when f=1/3).

Shift size
The purpose of using a control chart is to detect a shift in the process mean, of a specific size. To detect a shift of two standard-deviations-of-the mean, enter the value 2.

SPC
Statistical Process Control.  

SQC
Statistical Quality Control.
