Although Guangda has submited the corresponding analysis report, they do not cover the reasons regarding with the production, so right now they only can 1 take corresponding measures to prevent the non-conforming products from leaking out of the company. In addition, based on the May Audit and Aaron's visit in Sept., we specifically arrange this visit to confirm and communicate the improvement together with the related FMEA/CP/WI and other documents on site. Since we have not received the electric fuse failure parts, we preliminary analyze the main reason of electric fuse failure is the connecting length of thermal fuze and enameled wire is too long, leading to a small gap between the ends of the connection and the metal shell of the coil. Now Guangda's measure is just keep using 1000V and 3 2 second High-Pot inspection (they do not use 500V anymore) and 1 minute retest the nonconformings. In addition, we need to conside how to prevent and confirm the problem on site from the production view. Currently we just use fixed insulation bush in the middle, and we can implement the following measures and analyze deeply after we receive the failed coils Except for the fixed insulation bush in the middle, both ends also have to fixed. The fundamental purpose is to control the the gap between the ends of the connection and the 3 metal shell of the coil, to make sure there is enough distance. (Our experience is if we guarantee the gap distance over 0.5mm, it will be more effectively insulative when we inject the plastic resin) Currently, our insulation bush has no silica gel layer, and the insulation effect is 4 very poor. We need to replace them by insulation bushes with silica gel layer. Before we receive the failed coil from TCCI, we need to find an appropriate third-party to carry out X-ray flaw detection to analyze the failure internally before destruction and to ensure the accuracy of the analysis. Corresponding explanation should be attached to the analysis procedure. Guangda finds several testing organizations to proceed X-ray 5 flaw detection. The outcome seems to be not very good beacause the metal shell of the coil is 1.5-3mm thick, while the permeability of X-ray is not good. X-ray flaw detection usually has a pretty good effect on nonmetal or thin metal products. So we suggest to proceed "Industry CT"
to the products to get a fine outcome. And we will use the similar failure products for the CT before we receive the failed products. 主持人Moderator 李明胜 We confirm the key control character (KCC) in thermal fuse production process with our suppliers and get relevant SPC reports. (After talking with the suppliers on site, we learned that the KCC of thermal fuse is internal resistance.Beacause of the 100% online inpection, there's no corresponding SPC reports available, but they can offer some corresponding measured data for CPK analysis. We planed to visit their company, but their but their sales staff were not at company, so we didn't go. High-pot seconds. 1000V, 3 are also inspection requires 500V for 1 minute, but actually it needs 1000V for 3 We have comfirmed on site that corresponding data is effective( If we apply minutes to select the non-conformings, and then apply 500V for 1 minute, there 35% can pass.) But Guangda must offer the relevant written documents. 0.00% 0.00% 0.00% 6 7 8 9 10 11 The main reason of diode failure is no assembly of the diode or reversed assembly of the diode or original non-conforming of the diode, which leads to short circuit and open circuit. Although now we can proceed 100% inspection to detect the short circuit and open circuit (to provent the non-conformings leaking out),of wethe must improve as Add diode assembly work station. There is no from Poka-Yuko fuction current tooling, which has to be improved to make sure the coils are fixed correctly. Also, the work instruction should be also perfected, and how to assemble the diode should be specified in WI todiode avoidinspection any mistakes of no assembly or reversed assembly. Thethe current device does have the ability to select the non-conforming diode out, however, the alerting way should be adjusted. The current status is: we can judge if the diode is short circuit or assembled reversedly by energization. (If the red light is on or there is an alarm, we will consider the diode is non-conforming). After it confirmed press thestarts green control the circuit in Theis 100% on-lineconforming, inspection then for the diode on Oct. button. 28, and Energize we will also carry out a 100% inspection for the current inventory. After the inspection, we need to mark on the outer box so that TCCI can double confirm the effectiveness of the diodes. (The failed coils that TCCI Assembly Plant found on Oct. 26 are actually because of the failure of the diodes) GD needs to do a further analysis and provide an 8D report. We have carried out most of the corrective items that TCCI brought up in May Audit and Refine the non-confirmings in details: Scrap area and to-be-processed area. In scrap The coil inspection has already done in a line, which has improved obviously. However, since it is dynamically circulated, we still need to think about how to prevent any products from no inspection at all during the 100% inspection. (We have confirmed an easy way, which is to add baffle rod). So Guangda will consider how to implement in the future. The man-machine engineering consideration: individual operating station (E.g. High-Pot Inspection), because staff can be easily tired by doing the same inappropriate actions (Site operators have proved that, we should consider how to improve. Bck to Sept., TCCI has proposed to intall bearing press assembly work station, and we hope Guangda can also consider how to further improve.This working procedure is the key process for companies like Sanden and they themselves carry out the whole press assembly Others: For the statistics and classification of non-conformings, if we are not sure which non-conformings are the most. Through the on-site explanation, we can Classify bad coils, and found that high voltage breakdown is the highest failure reason (It is also proved that the current high-pot inspection is effective), Coil is also high failure products. Besides updating the corresponding FMEA, statistical methods should be further improved. At present, we will work on to improve coil statistics (We have reached an Update 8D, the current 8D does not have clear D3's(contain) information, we have offered reference versions, and we suggest to use in the follow-up work.At the same time, update the current 8D report which has been submited and affirm the results for the thermal fuse choice. After the selection of the diode we also need to update corresponding 8D report. Since this type of failure mode is not specified in previous FMEA, we need to update it into the FMEA. At present, quality statistics doesn't include customer's complaints, we need to add it 12 the visit in Sep., however, the following items need to be further improved: 13 area, we use color red while in to-be-processed area, we use color yellow. 14 15 16 17 18 19 to carry out continuous improvement more effectively. 备注Comments: XX 今天Today: 按时完成 Closed on time 7 63.64% 2015-2-14 延期完成 Closed late 4 36.36% 日期Date: 地点Location：
