soldering

I’ve started the soldering session with the top tube pcb. To see, if the pinheader have a good connection, I made a ‘pull-test’

On the 4pin pinheader I used to much force and the hole pinheader with it’s solderpads are screwed up. To fix that, I used male jumper wires and I soldered the wires directly to the traces and fixed them with hot glue.

Here you see a picture of the complete tube board…
In the background is the controller board. There you can see e.G. that I’ve not used an onboard dc jack.

I went ahead with the controller board…

Here you see, some of my 0-Ohm bridges and the ds1307 rtc module.
I isolated the backside of the module with some tape, to avoid short circuits, when it’s soldered to the board.

And of course I found some traces that where not connected properly because of bad soldering and / or the strange holes, milled by the LPKF.
I made some ‘Frankenstein’ and soldered wires, to the not well connected parts.

This is the screwable dc-jack I used. In the background is the NCH6100HV high-voltage step up converter.

Here you can see the finished electronics. For the surface ‘effect’ I just used a double sided pcb and sanded the surface, to avoid short circuits…
