How do reattach a replacement Series 2 LCD flex ribbon cable?
I have a replacement iWatch Series 2 LCD Flex Ribbon Cable. How does it attach to the circuit board. Does the Flex Ribbon have an adhesive backing?
Apple Watch Series 2, announced September 7th, 2016 and released September 16 2016.
According to one of our teardowns at iFixIt, the LCD is connected using ZIF connectors, which stands for Zero Insertion Force, meaning you can insert the cable with very little force (Citation from wikipedia: "The two sliding parts of the connector are then pushed together, causing it to grip the wires").
So no need to worry about any locking mechanism for the cables.
If you mean coming directly from the SiP, those I don't know of any replacing method or locking mechanism
