Should I be Worried? inconsistent tinning.

I know Itead are recalling some of its units...


Should I be worried about the little amount of tinning on the AC power track? also there seems to be a extra capacitor soldered to my board, something I have not seen before.


I have just got 4, all with inconsistent tinning and extra capacitors thrown on

Sorry about your troubles

 - I would be worried


I assume high voltage is concern for you?

Attention to details perhaps important?

But you missed you post in the wrong forum


Missing with high voltage is a dangerous thing.

were did you buy such Nextion HMI displays?


I also like to buy Nextions with ESP8266 on board ...


In a more serious manner,


The recall link is here:

https://www.itead.cc/blog/sonoff-th16-and-pow-recall-notice


If bought from Itead, send photo and order number to ticket where told

- they will look at and tell you if this is problematic or not


If bought from another supplier,

you will need to go through the reverse order

 - to your supplier whom you purchased from

    so they can get a ruling and if need be a replacement


But for safety, it is best to check first before using.



Thank you for your responses!


I brought them from Store: Sonoff Oficial Store

I've contacted the supplier, raised a dispute.


I'm just glad I checked them over before use, Thank you!


oh and what forum should it have been posted in?

Sonoff Oficial Store ... "Official" ?
AliExpress is not Itead.

When you purchase from Itead, higher quality assured

 - all are new in box and not customer returns

 - have not been used before

Shorter process to get support.


the ewelink app says "United Kiongdom" so I don't get to caught up in the translation.


It was the free postage and packaging that got me, I am a fool :(


I really do appreciate your help
