Problems with the connector plating process
In the process of manufacturing the connector, many process-related problems are involved. One of the more important parts is the electroplating process. Do you know which plating process problems exist in the manufacture of connector products? The following Konnra Electronics electronics engineers will give you a detailed introduction to the connector plating process.
First point: establish long-term cooperation with electroplating manufacturers
1. It is necessary to establish long-term cooperative relationship with 2-3 electroplating manufacturers. Remember to reduce the cost at the moment, and frequently change the electroplating manufacturers. In order to facilitate the management of product docking, it is best to control the driving with the electroplating manufacturer. - Within 4 hours.
2. In order to facilitate the management of quality stability and traceability of many electroplating plants, different series of products can be adopted, and different electroplating manufacturers are selected. Do not have electroplating by electroplating manufacturers in the same series of products.
Second point: the supplier management mechanism for common development
1. The PK of the quality, delivery, and coordination of the electroplating factory should be rated once a month.
2. The electroplating plant should be required in accordance with the AIAG CQI-11 electroplating system standard, and regular management review should be carried out at least once per year.
3. The quality technology review and improvement meeting with the electroplating manufacturer should be carried out regularly; at the same time, the communication and execution of the customer requirements, the connector manufacturer and the electroplating manufacturer should be synchronized.
Third point: verify the ability of electroplating products
1. The electroplating product feeding verification project is completely synchronized with the electroplating manufacturer, and it is necessary to verify the plating film thickness, tin adhesion, adhesion, solder heat resistance, corrosion resistance and the like.
2. Electroplating manufacturers must have at least verification equipment, such as: film thickness tester, salt spray tester, high temperature oven, dip tin balance, 10-50 times microscope.
3. The electroplating product should be set according to the plating batch number. The electroplating product of the same batch is set as an inspection lot, and then the sampling is performed according to the reel flow number of the batch, which can reduce the sampling failure.
Fourth point: storage and circulation management
1. The length of time for electroplating products (terminals, gaskets) to be assembled from the warehouse to the workshop should be controlled within 7 working days.
2. Conditional connectors manufacturer, qualified from the plating product, and then into the waterproof bag + desiccant seal stored in the constant temperature and humidity warehouse is better.
3. Electroplating products must be stored in a constant temperature and humidity warehouse. The storage conditions are: temperature 20 +/- 8 degrees, humidity below 65%; in the industry, the general standard is temperature 30 +/- 8 degrees, humidity below 75%.
Fifth point: traceability and packaging of electroplating products
1. After assembling the product in the production workshop, all vacuum packing should be carried out, so as to prevent the poor plating caused by the moisture in the transportation after the finished product leaves the factory.
2. Establish a trace management mechanism for the connector product batch management. The connector manufacturer can trace the information such as the terminal stamping batch and the terminal plating batch with the batch number in the label of the product, so that when the client has bad feedback. The connector manufacturer can report the problem batch in the first time to prevent bad repeatability, thereby reducing the bad losses of both parties.
