System Assembly Troubleshooting / How can I make the focusing slider moving well?

« on: February 07, 2018, 03:53:45 AM »

Hello, I'm having problems with the focusing slider.
As I move the focusing slider, the focusing slider becomes more stiff and harder to move.
As a result, it is difficult to adjust the focus.
How can I fix this?

Thank you.

System Assembly Troubleshooting / Could I get some tips for soldering coaxial cables?

« on: December 13, 2017, 12:31:45 PM »

Hello, I read some helpful tip from other post "Soldering Coaxial Cable to CMOS Imaging Sensor PCB  (Read 212 times)"
But I can't understand how to do it:
Also, there are multiple ways to solder the coax cable, some easier than others. What you might want to try is buy a pair of 50mil pitch headers. You could then solder a 2 x 1 female header, https://www.digikey.com/product-detail/en/mill-max-manufacturing-corp/851-43-050-10-001000/ED90265-ND/1212162, to the 2 holes of the CMOS PCB and then solder a 2 x 1 male header, https://www.digikey.com/product-detail/en/mill-max-manufacturing-corp/850-10-050-10-001000/ED8250-ND/279659, to the signal and ground lines of the coax cable. This gives some extra room to work with when soldering and you also have the added benefit of having a cable that can be swapped between CMOS PCBs. The down side is with enough force, the male header can pop off of the female header. The parts I linked to come in a 50 x 1 pin configuration. You just need to break off 2 to get a 2 x 1 header.

Could you give me some any visual materials or detailed explanation to help me understand?
Because I have difficulty in soldering coaxial cables, and so I want tip for soldering coaxial cables.
I hope this information helps me solder coaxial cable.

Thank you.
