List of the tools and techniques you used to take it apart
– Small screwdrivers for wedging the plastic casing apart and unscrewing the PCB from the bottom casing.
– Large flathead screwdriver for prying the casing open.
– Small wire-cutting plier for cutting the faraday shields.
Materials and techniques used for each component
1. Roku’s and Remote casing – made out of ABS plastic. The plastic is heated and injected into a mold to take the shape of the case.
2. Faraday shield – made out of thin aluminum. Made to enclose and block electromagnetic fields.
3. Toshiba TC58NVG1S3HTA00 flash memory – made out of plastic/epoxy
4. Button pad – made out of silicone rubber using a mold. The design and color are UV printed.
5. Circuit board – made out of a combination of prepreg, laminate, copper foil, soldermask, nomenclature, final finish.
Chips
1. Toshiba TC58NVG1S3HTA00 – storing data?
2. Samsung K4B4G1646D-BYK0 DRAM Chip – storing data?
3. Broadcom BCM7218 – The brain of the system
4. Broadcom BCM43143 – Wifi IC.
Two interesting design elements
1. The Roku’s plastic case is very tightly shut. I assumed that it was held together with glue since it was so difficult to pry apart but ended up finding no glue at all. It was designed with edges that lock the parts together which does a good job securing all the parts within so that no one will unintentionally open it.
2. The sheet of buttons is also very fascinating. The way all the raised buttons are connected on a sheet to make sure they all stay together and in order so nothing will get lost or reorganized.
