Overview of the battle-field side of the toucam's PCB, cuts already being applied |
|
Practice cut.... get rid of additional light produced by the green SMD-LED |
|
These cuts are essential (see link (2) mentioned above), cutting too much of the mass-plane does not harm, but... watch out for the other leads! I used a sphere type diamond-tool to mill away the leads to be disconnected. |
|
Wires do not need to go around the PCB in any case. Here are two vias which can be used to solder [Pad8] to pin 1 of the 4011 (lower wire) and [Pad10] to the potential switch (upper wire). I used 0.2mm "magnet wire" (enameled copper wire)... In these places, the wires are soldered to the PCB-vias. BTW: finally I did not add a switch to the cam... what for anyway? |
|
The leads (0.2mm magnet wire) connecting "Pin8" to pin 11 (4011) and [Pin10] to the 100k resistor. Both wires use "foreign" vias to channel to the side of the PCB (as long as the enamel varnish is not scratched at the tunneling portion of the wire, no problem can be encountered). |
|
Both sides of the story.... the blue wire is the power supply for the 4011. (Sure, I could have searched for another place to get 5V from.... but, time is money, isn't it?). |
|
And... on the other side of life.... Dead bug "mounted" (cyan-acrylate) 4011 with 100k resistor. In the upper quarter of this image the connection between [Pad8] and pins 1 and 2 of the 4011 is visible. The lower quarter show the "tunneled" leads to pin 11 (4011) and to the 100k resistor. |

Dead bug 4011.... the two blue wires are the link to the parallel port connector. |
