I'm going to make a duplicate of this pcb, for another 3d printed desoldering unit. Using replacement C088 element/barrel/nozzle.
Using CadSoft EAGLE to try recreate this layout. but so far not 100% certain of the components list.
It looks like a 2 sided pcb, it lets light through, I marked a red arrow is that a via bridging top and bottom circuit?
The silkscreen info has
1.5k resistor / 470ohm yet have the same colour bands.
same for the two 470ohm resistors.
Potentiometers are unknown ohms, Is it ok to turn these or will they be calibrated?
RW 203
10K
VT3
Also attaching the bare pcb layout the traces are damaged, and hard to see so I defined the copper in black.
any help or advice would be appreciated thanks.
