So, After submission of my Project ( NorthPole Navigator ) and the deadline here are some of the updates that happened:
I got the Fedex Parcel with my PCB today
\
Why did i post this "Excuse"? Well it's not an excuse. It's about making others informed of a possible risk in their development process. I chose PCBWay because they had the best tolerances when making the PCB in white soldermask. That high tolerance is needed because of the small size and the QFN Parts. And i needed white solder-mask for best reflection. The light from LEDs hit the diffuser sheet and only some of them is transmitted through the diffuser the rest is bounced back into the PCB. Having any other color than white on PCB solder-mask will absorb some of the light before reflecting back into the diffuser. That's why you'll notice most of the high power LEDs having white soldermask. Plus PCBWay is quite affordable for the white solder-mask and in my past experiences FedeX almost delivered within a week of shipping. But this time customs was not that forgiving. Thankfully as every engineer should have, I had a plan B.
Will post a new project with the PCB assembled and Tested
