步骤 9
The membrane is composed of two thin layers of plastic that are - guess what...glued together. They are very difficult to separate and patience is key. Use a thin blade to separate the layers at a corner (it helps to start at the corner closest to the faulty keys) and very slowly peel the layers apart. You probably won't need to separate them all the way, just enough to expose the region of the defective key should do. On the inside you'll find a mess of white lines and dots. These are the conductive traces. Track down the two pads that align under the key(s) you are having problems with.
Locating the fault
  • The membrane is composed of two thin layers of plastic that are - guess what...glued together. They are very difficult to separate and patience is key.

  • Use a thin blade to separate the layers at a corner (it helps to start at the corner closest to the faulty keys) and very slowly peel the layers apart. You probably won't need to separate them all the way, just enough to expose the region of the defective key should do.

  • On the inside you'll find a mess of white lines and dots. These are the conductive traces. Track down the two pads that align under the key(s) you are having problems with.

  • With your multimeter, set to measure continuity, check there are no breaks in the tracks between the pad in question and it's neighbours. You can follow the lines to see which ones should be electrically connected. Some areas are coated in plastic, so you'll have to work around them.

  • Try to find the exact point where the track is broken, and make a note of where it is. A page marker is great for this.

这层膜是由两层薄薄的塑料组成的,猜猜是怎么组成的…又是用胶粘在一起。他们很难分开,耐心是关键。

使用一个薄刀片在一个角落来分离(最好从最接近故障键的角落开始),并非常缓慢地剥离层。您可能不需要一直将它们分开,只要足够暴露出有缺陷的按键区域就可以了。

在里面你会发现一堆白线和白点。这些是导电线路的痕迹。找出你有问题的键位下面的两个点。

使用万用表,将其设置为测量导通性,检查相关焊盘与相邻焊盘之间的电路是否有断裂。你可以按照线路来看看哪些应该接上电。有些地方涂了塑料,所以你得在它们周围工作。

试着找出轨道断裂的确切位置,并记下它在哪里。最好在一张纸上记下来。
