How Can a Professional Car Radio Factory's Quality System Be Evaluated?

What quality system certification should a qualified professional car radio factory have?

A automobile audio factory requires at least three years to build the first system from the facility's construction. At this point, it can effectively only get the ISO9001 basic quality certification system. A facility with ISO9001 quality certification may completely fulfill the aftermarket and semi-before market manufacturing standards. However, in order to meet the demands of increasingly demanding auto manufacturing project clients, it must achieve the globally recognized IATF16949 production quality system certification. To achieve the IATF16949 factory auditing standards, however, IATF16949 certification needs at least 5 years of mature factories, from the scale of staff, production test equipment, engineering technology precipitation, production process perfection, quality control degree, and so on.

There are numerous procedures that can be done when analyzing a vehicle radio manufacturer to ensure that the factory is capable of manufacturing high-quality items that satisfy your criteria.  

These stages are as follows:

1. Through the factory staff meeting presentation, you can gain a basic understanding of the factory's development history, current scale, the status of production and testing equipment, collaborating customers, representative project cases, and corporate development visions, among other things.
2. You can tour and assess the office area, material management department, engineering department, quality control department, and laboratory, as well as the present situation of the production workshop and warehouse, guided by factory employees, to acquire a broad sense of the factory.
3. Inventory assessment. You may primarily evaluate the IQC department to see if the factory has a rigorous division of inspection zone, IQC zone, and defects zone, as well as a daily record of IQC inspection reports, testing standards, and return records. Furthermore, whether or not each core material has engineering-signed samples for IQC control testing. Additionally, determine whether the warehouse has distinct storage space divisions for various materials, such as a hardware section, a plastic section, a wire section, a PCB section, a precious materials part, and so on. Check to see if the precious materials area, such as an integrated circuit or a display screen, has a constant temperature and humidity preservation environment. A thermometer, hygrometer, air conditioner, and humidifier are required for the precious materials portion.

4. Evaluation of SMT workshop. When moving from the PCB section to the SMT workshop, make sure there is a dedusting and destaticizing space at the entry, and that SMT personnel and reviewers wear anti-static clothes and helmets accordingly. In the SMT workshop, look for SMT records, AOI inspection reports, and furnace temperature record reports for daily production, as well as the manner solder paste is stored and the location of the refrigerator (unused and unpacked solder paste must be stored in the refrigerator).

5. PCBA assessment. Following the completion of the SMT assembly of electronic components, the semi-finished PCBA will be transported to the manufacturing line's post-welding department. Larger components, such as inductors, must be physically welded to the PCB by PCBA welders. Check to see if the PCBA operators are wearing anti-static wristbands, if there is a temperature detection standard for the coil head and detecting equipment, as well as the tin dross cleaning procedure, and so on. These are the quality control details that evaluate if there are quality hazards in the product's long-term use.

6. Evaluation of the Assembly. Based on the following criteria, evaluate the assembly department employees, manufacturing technology teachers, and repair workers. To begin with, each worker in the operation must wear anti-static wristbands, and each assembly line has a QC staff at the end position for initially finished product inspection. The faulty assembled final items that QC staff initially finds require a clean placement location while repair staff works on them. In addition, you may monitor the work sessions and daily repair reports of repairers who assemble damaged items to ensure that employees' methods are uniform and clear.

7. Evaluation of the aging chamber. Check to see if 100% of the assembled completed goods enter the age room for the aging test, if there are clear specification papers on the temperature, standard, and duration in the aging room, and how the aging faulty product processing process is run.

8. Quality control of the finished product. After age, qualified completed items are turned over to the QC department for further testing; ensure that each QC station has defined testing content and criteria. In addition, review QC reports, display QC faulty product handling and procedure, and display QC station job instructions.

9. Evaluation of packing. After stringent QC testing, the finalized product will be turned over to the packing department to complete the final packaging. You can see if the factory personnel performed a thorough exterior visual inspection, wiped the film, validated the product barcode, and checked the stickers.
10. Before formally entering the warehouse into the ERP system, the finished and packaged batch orders must be randomly reviewed by QA to validate the batch orders' quality. Check to see if the QA department has comprehensive documentation of the sampling criteria and techniques.
11. When qualified batch items reach the warehouse after QA testing, you may determine whether the factory's PMC department management employs a professional ERP system to eliminate manual activities.
