搜了一下，
上拉电阻

pull-up 7.5k Resistors ("printed" on the ribbon circuit boards) also need to be put back in the circuit as they're built into the ribbon board and when it's removed they're not, and the controller will act up on you if these are not in the circuit. There needs to be 2 of these pull-up resistors installed, one goes from V_STBY to COM1, the other goes from V_STBY to COM2. If you don't have any 7.5k resistors you can use anything from 6.8k to 10k really, but they do need to be installed since the ribbon board is removed when building an arcade stick, all of the PS3 controllers are setup this way and need those pull-up resistors if the ribbon board is removed

这篇写的更明白，阻值都有了

俺之前搜的资料怎么说这电阻是4.7k，到底4.7还是7.5纠结了，昨天不该把烂手柄的薄膜给扔了的，装回去的手柄又不想拆了。。。。。

4.7k是以前经验值的上拉电阻。这个一拖几，大概又不一样吧。

新手柄薄膜有问题？

淘宝有卖的，就是得花点时间。
另外，版本得搞对，这图里的脚印不对，是两排的，就不行。
