3M 防滑貼 去除測試

 把貼皮撕掉後，試了

去漬油	-效果最好 -清完的表面不會油/ -但好像成本蠻高的
WD40	-效果普普 -噴完的表面會油油的
酒精	有效但膠很厚的防滑貼 除起來不太夠力
乳液	感覺也有用，但一樣不夠力
煤油	-很容易用牙刷清掉，但擦掉還是會有一層油油的 -而且會很臭

Garmin Vivosmart HR teardown

I got this device from Garmin Service because my previous Vívosmart was dead.

This is an old device and it dies due to the battery not charging anymore after about 2 yr.

Here is the teardown log.

Use hot air(150C) and glue remover.

Took some time to pill it out.

Here it is.

Battery soldered directly on FPC.

Battery spec. 331223(pretty hard to get)
