Critique my first PCB

<< < (7/17) > >>

carl0s:
nevermind, I have sorted that ground pour for C4

carl0s:
I've got an important question.

C1 (100nf) and C3 (1uF) are in parallel, right next to each other.
This is because the original schematic had C1 on the power into the board, and then the datasheet schematic for the backlight driver had C3 (1uF) in it.

Should I ditch one of them? Obviously this elementary question will highlight my naivety and lack of knowledge on basic electronics :-/

I have beefed all the caps up to 0805s, for ease of placement, and availability on the higher voltage side (~18 - 20v).

BrianHG:
If J1 is a single sided flex cable connector, the pins where you length equalize extended the traces may travel into the connector to the flex cable with a little more length inside the connector compared to the pins right under the connector.  Have you taken this into account when extending those 2 traces to their length on the PCB?

Hi. Do you mean that they may have already compensated for the connector pin separation in the flex cable?

carl0s:
boards have come out looking reasonable, and the pads line up too :)

I'll report back if they actually work, once I've finished my reflow oven.
