Hi Tony 0001493:0010610 Question about LED, at report page 6, this board was passed FT1 station. But FA report from the vender, LED inner gold wire was broken. I think it was no LED light also in the factory. So, Please update 8D report again that how LED tested it before 4/23 and why FT1 station didn't find it. Thanks SON |
|
|
Hi SH Son 7. Tact feeling is not good issue: Fii update spec tact SW tension by vendor and measurement the defected tact SW tension by ME. The result : Fii uses a force gauge to check the status of the actual switches on the PCBA of customer feedback. Measurement results are in standard specifications. Regards, Rachel image.png (13,913 bytes) |

Hi SH Son Fii feedback this issue: "Question about LED, at report page 6, this board was passed FT1 station. But FA report from the vender, LED inner gold wire was broken. I think it was no LED light also in the factory. So, Please update 8D report again that how LED tested it before 4/23 and why FT1 station didn't find it." Fii update LED no light 8D report . Root cause Escape LED no light to next station. 1. That time ( 12-Apr ), production line did not check LED by the auto testing program. 2. OP check LED by visual inspection at FT1 station may be he did not check carefully and passed to next test station. Regards Rachel |

Hi Rachel 0001493:0010626 7. Tact feeling is not good issue: The result : Fii uses a force gauge to check the status of the actual switches on the PCBA of customer feedback. Measurement results are in standard specifications. BFX-UA300 (96.1517T00) RMA Power Button Feeling Report 20220813.pptx (1,630,911 bytes) -> ALT Feedback I reviewed your report, tact switch push force within the spec. SPEC : 160 +/- 50 gf (Lower spec : 110 g.f/ /Upper spec :210 g.f) measure : 116.5gf But, customer quality manager defined this NG case. because only one button felt bad that. So,Please check that factory can manage it with +/- 20gf tolerance with around 3 button. ( see attach image) Thanks SON image-2.png (10,592 bytes) |

Hi Mr. Toney Tu, I have question on https://mantis.cnsbg.foxconn.com/vaas/view.php?id=1493#c10660. You sorted 35,242 pcs totally. But your 8D report said that total q'ty you have is 67,397(page 4). So will you keep sorting rest of q'ty, 32,155 ? If yes, then when will you finish it ? Best regards, SuhYoung YOON |

Hi SH SOn 1. HDMI on Fii stock have is 35242 pcs is sorting done 17-Aug. ( By FIT vendor manpower arrangement ). Done 2. HDMI on FIT vendor stock is 20K - FIT vendor had sorting 100% ( 03-Aug-2022 ) before shipping to Fii. Done 3. On the way have 1 lots- 12K from FIT to Fii foxconn . When we received this lots , we will inform to FIT for arrange manpower to continue sorting it. Due date : Aug-2022. Many thanks Rachel image-4.png (10,289 bytes) |

Hi SH Son Sorry reply late this issue: 7. Tact feeling is not good issue: Tact switch push force spec change from 160 +/- 50 gf to 160 +/- 20 gf . 1. 19-Aug, Fii feedback to vendor confirm for change spec. 2. 19-Aug, FIT Vendor feedback , they had verify 10 pcs material ( on vendor side ) all is within spec. ( See picture ) Other, this Tact SW material they ship to other customer too. so difficult for change spec to 160+/-20 gf. 3. 20-Aug , Fii SQE feedback defect Tact switch push force test value, ( 0.1165 kgf - min spec ), request vendor more analysis this issue. Many thanks Rachel Ruan image-5.png (10,758 bytes) |

Hi Mr. Toney Tu, I have question about no. 2 feedback above. 2. 19-Aug, FIT Vendor feedback , they had verify 10 pcs material ( on vendor side ) all is within spec. ( See picture ) Other, this Tact SW material they ship to other customer too. so difficult for change spec to 160+/-20 gf. Do you mean your vendor, FIT, cannot change spec. due to other vendors is using same Switch ? I think that changed spec. we asked is in spec.. I think your vendor can keep spec. with your vendor's other customer even though they may change the spec.. If I have any misunderstanding, then please correct me. Best Regards, SuhYoung YOON |

Dear Mr Sy Yoon About Tact SW spec issue. Many thanks for your understand my email. FIT vendor confirm can not change spec Tact SW, ( they keep spec 160+/-50gf ). Many thanks Rachel Ruan |
|
|
Hi Rachel my understanding is that hard to change the tact sw due to common sw from vender So,Please check again factory can manage it with +/- 20gf tolerance with around 3 button when assembly ( see attach image) Thanks SON 이미지 213.png (18,404 bytes) |

Hi SH Son Here is '2022.05 Mass production inspection report update action 1. Item LED no light issue 2. Power Button feeling NG issue. Pls help review it. Many thanks Rachel |
|
|
HI Rachel 1. Item LED no light issue : Please update the Action from LED vendor: Due date: 2022/08/29 after that, this issue can be closed. 2. Power Button feeling NG issue. : factory or FII find the solution that different tact feeling between around buttons I think that one way is manage tension force at the factory, the other way is change the tact switch of low tolerance (i.g. 20gf) without PCB / Housing change. So, please review and feedback to us. Thanks SON |

Hi Mr. Yoon, Sorry for update report late due to test SOC delay window. Please see the attached file. Thank you. |

Hi, Fu-chiang Young Could you check POR timing of RTL8211F on NG Board? Please refer to Ch.7.17 PHY Reset and Power sequence design. Best regards Lonnie Kim |
|
|
Hi Loonie, May I know what is the purpose for measuring POR of RTL8211F on NG board? Because we rework NG IC on good board and the issue is followed PHY IC, not followed PBCA. Thank you. |
|
|
Hi, Fu-chiang Young My means measure to NG IC not NG board. I want to know reset timing margin of NG IC. Best regards Lonnie Kim |
|

Hi SH, For tact switch issue, we asked FIT vendor which we use currently, they do not +/-20gf narrow tolerance switch. We also survey another QVL FXN vendor, Powerway and LIYANG. Powerway replied they also have not +/-20gf narrow tolerance switch. And the size has a little difference with original switch as currently we use. LIYANG did not reply yet. Thank you. |
|
|
Hi. Fu-chiang Young 0001493:0010771 1. Please find the alternative tact sw and upload the datasheet. - Pin to Pin. - Not change the PCB - narrow tolerance switch. +/- 20gf is just reference. 2. Please check factory can manage the tolerance after assembly or not. Thanks SON |

Hi Lonnie, Check the power sequence of RTL8211F, the rising time is over 0.5ms and POR is about 200us. Compare with OK and 2 NG PHY ICs, they look normal. Please see the waveform captures. BTW, River has test some boards for middle CRC delay value, 0x60, they are all pass. The some boards include 2 good boards and 2 NG PHY ICs, these 4 boards are all no CRC error. Thank you.

Hi. Fu-chiang Young Could you test CRC with reset delay over 10ms? I think NG IC would be Corner side, so I would want to provide enough reset time. Best regards Lonnie Kim ENET_PHY_POR.png (91,680 bytes) |
|
|
Hi Lonnie, This PHY Reset is HW reset, and currently the image did not to set low to reset PHY IC, but using SW reset to reset PHY IC. We also try to implement the HW reset by PHYRESET pin to pull low by hand for over 10ms, and check CRC error improve or not. The result is the same as before, still has CRC error and cannot improve anything. It seems CRC error not because the reset timing, but it is related about delay window. River is test more good units for CRC window and found even good units has different delay window. Thank you. |

Hi SH, The tact switch vendors(FIT/POWERWAY/LIYANG) had replied some informations and datasheet. They all said +/-50gf is for normal standard due to structure limit. Please refer to structure.png file. The internal is SUS spring(3) which material is metal with fixed bend for pressing handle position (5) to cuase touch on. So the spring has limited force as +/-50gf. If the requirment is +/-20gf, vendor has to screen out as bin code and that will be cost up a lot. Please see Powerway and Liyang datasheet. Also refer the structure capture. Thank you. spec-2.PNG (24,227 bytes) Structure.PNG (9,233 bytes) |

0001493:0010791 Hi, Fu-chiang Young Can you check provide doule reset(second reset proivde after 10ms)? Best regards Lonnie Kim |
|
|
Hi Lonnie, Double reset? Do you mean SW and HW reset? We have try to pull low PHYRESET pin and retest the CRC error, it does not have any help to NG PHY IC CRC error. We think the issue is not here but the issue is on CRC delay window range. River has done some units CRC delay window and we will update later. Thank you. |
|
|
Hi Mr. Yoon, Update the report of CRC error. River has test 10 good DUTs for SOC window range investigation. The middle of the SOC delay value will be 0x60. The criteria is to test iperf in RX direction for 600 seconds and no any CRC is found. Next we may need to do long term test(24hrs), Please see the attached file. Thank you. |
|
|
Hi Mr. Yoon, Update the datasheet of Powerway customized tact switch. The cost had sent to Fii PM and Fii Sales. They will provide the cost for ALT. Thank you. |

HI fu-chiang Young and River, Can you me know how can change register value in adb shell ? I have one box which has same issue, so I want to test it after changing register. Thank |
|
|
Hi Mr. Wooshin, The command as below: adb shell su mdb sys mem w 0xF7EA0A18 0x00600040 1 mdb sys mem r 0xF7EA0A18 1 ethtool -S eth0 River had release new image with 0x60 for SOC middle delay value in mants 1506. Thank you. |

Hi Fu-chiang Young 0001493:0010883 about tact switch spec. change to 160 +50/-30gf [ALT] if the tact sw cost is same, let's try to review the tact sw change Please prepare the tact sw sample that min / center / Max for each 10 pcs 1. Min sample : 130gf 2. Center sample : 160gf 3. Max sample : 210gf Thanks SON |
|
|
Hi Mr. SH, FIT only can provide 160+50/-30gf samples, cannot provide 130/160/210gf samples. Because it is hard to screen out samples, FIT only can make sure 160+50/-30gf samples. Does ALT still need samples? If yes, please provide the address and cell phone number. We will let FIT to send samples to ALT. Thank you. |
|
|
Hi Fu chiang Young Please let me know Whitch vender customized tact switch FIT or Powerway? I was little confused your answer. 0001493:0010205 upload only powerway. But f 0001493:0010981 feedback FIT. Thanks Son |
|
|
Hi Mr SH, The tact switch customized vendor is Powerway. 0001493:0010981 is FIT sample which FIT cannot provide 130/160/210gf tact switch. FIT only can provide 160+50/-30gf sample. Thank you. |
