IPQC is In-Process Quality Control, which refers to the quality control of a product from the time it is put into production to the final packaging of the product. IPQC is also known as In-Process Quality Control,or In-Process Quality Control. IPQC is also known as Inspection Patrol because the inspection pipeline used by IPQC is a roving inspection between the various processes in the production process.
IPQC generally adopts the pipeline for random inspection,and the inspection contents are generally divided into random inspection of product quality of each process,inspection of the work pipeline and method of each process operator, and point inspection of the contents of the control plan.
What are the duties of IPQC?
1.According to the daily production, strictly according to the inspection standards to check the production of the first piece, inspection of products.
2. Stamp the first piece of product after inspection as qualified and place it in the corresponding position.
3. When non-conformity occurs, notify the relevant personnel to improve immediately to avoid causing batch defective products.
4.Follow up on unstable products, report to supervisor or relevant personnel when there is any problem, and find out the solution to solve the problem in a timely manner.
5.Assist the head of the customer feedback, complaints, and ensure that the warehouse inventory of defective and good products are effectively dealt with.
6.Responsible for the first piece of the signature plate confirmation, and to ensure that there is no model not to produce, unqualified not to ship.
7.Coordinate the quality management in the workshop.
8.Perform inspection tasks, according to Huawei, ZTE, different requirements of the customer files and inspection guidelines to complete product inspection, sampling work.
9.Perform first piece and on-line material confirmation work according to self-made work order, electronics, BOM structure, ECN, contact list, software release form, checklist, and so on. First article confirmation according to different inspection files for different customers' needs.
10.Work with the production line to confirm the return of materials.
11.Check the inspection equipment and use the equipment to complete the inspection tasks.
12.According to the related file ‘bar code information meter’ on the product label inspection, and scanning action.
13.Provide records of defective materials for trial production.
14.Receive, classify, archive and recycle controlled files.
15.Conduct inspections and audits on production line 6S, ESD and other aspects affecting quality, and promote the improvement of production line processes.
16.Record and complete related quality reports.
PCBA Production
What is the work of IPQC?
1.First Inspection: All products can be mass produced only after the first piece is inspected and passed.
1.1The production line notifies IPQC 1 hour before the production start, and at the same time provides 3 sets of inserted finished products for the first piece inspection.
1.2IPQC will check whether the material specification, piping, welding process, power efficiency, etc. are in accordance with the file requirements according to the BOM list, Operation Instruction, Customer Acknowledgement and other files.
1.3Fill in the ‘First Piece Inspection Form’, if it is qualified, it needs to be signed by the engineering department and the production supervisor or above before notifying the production workshop to carry out the production. If it fails to pass, we should post a mark of failure and notify the engineering department to find out the reason together and carry out the inspection again before notifying the production. If the first piece of inspection fails, if it involves the functionality of the product, we need to issue a ‘quality exception list’ and submit it to the science and technology department. Each time the first piece must have three for the first piece of sealed samples.
1.4After the first piece passes the inspection, label it and indicate the specification model and inspection time on the label, the three first pieces are placed in the insert QC, post-welding QC and testing station as the sample of this batch of sealing respectively, and when this batch of production is completed, tear off the label of the first piece as the qualified finished product to be shipped out before the package is shipped out.
1.5Product batch production process to do a short stay in the event of significant changes in the start of production again also need to carry out the first inspection. Such as the replacement of material models, operating pipelines, process changes.
2. Inspection: the entire production process of material use, assembly operations, machine operation, environmental compliance, such as a full range of regular checks to confirm.
2.1 Inspection frequency is once every two hours, the inspection content is shown in the ‘IPQC Inspection Daily Report Form’, and the corresponding items will be ticked in accordance with the requirements of the file. Audit: Head of Department, Permission: Department Manager. Chromium and electrostatic rings are measured before production in the morning and afternoon after work.
2.2 Inspection focus: In addition to the verification of the contents of the ‘IPQC Inspection Daily Report Form’, we pay attention to the key processes and new employees' workstations in the operation instructions.
2.3 Inspection sampling: In the inspection process on the production line to carry out irregular quantitative sampling test, record the sampling results in the back of the day inspection sheet.
2.4 Defective product handling: In the inspection process found or told that there are defective product phenomenon, response path: team leader - production supervisor or PIE (according to the defective phenomenon, such as just man-made operational problems, then directly respond to the production supervisor) - QC - the relevant responsible departments to deal with. If the continuous defective product reaches the standard of stopping the production line, IPQC should follow the ‘Production Stop Line Management Regulations’. If the quality problems found during the inspection are not caused by human operation, and involve problems in process files, standards, and functional performance, IPQC should issue the ‘Process Exception List’, and submit it to the same route as the response route of this article.
2.5 Daily non-conformities and quality problems and the way to deal with them are summarised after the end of the production day and registered in the ‘IPQC Inspection Non-conformity Record Sheet’.
Summarise the daily work of IPQC:
1.According to the daily production, strictly in accordance with the inspection standards to check the production of the first piece, inspection products.
2.Stamp the first piece of product after inspection and place it in the corresponding position.
3.If there are unqualified products, notify the relevant personnel immediately to improve and avoid mass production.
4.Follow up the products with unstable quality, report the related problems in time and find out the solutions.
5.Assist the head of the response, complaint handling, and ensure the effective handling of the warehouse inventory of defective and good products.
6.Responsible for the first piece of the signature plate confirmation, to ensure that no production without the template, unqualified not to ship.
7.Co-ordinate the quality control work in the workshop.
The above is based on the IPQC work of PCBA manufacturing parts.
