It also could be a issue with the quality of the photo im seeing.
Here are a few examples related to, reflow issues, rework, layout issues causing automated soldering issues in wave solders etc resulting in post automation hand work. Lets just say this is the worst of the worse Ive seen on this piece and is not acceptable in ANY WAY for our products and the person responsible was let go.
This is an example of 100% untouched full automation SMT P&P and Top position P&P with automated soldering.
Things to look for here -
1) Smooth transitions on all contact pads to connection points on the devices
2) No discoloration anywhere on the PCB
3) smooth flow marks across the top mount P&P components
4) No bubbles or air pockets in the solder joints
These are all just examples of things to look for whenever looking at any electronics. Re-work is par for the course in the electronics industry. Most large ISO 9001 compliant manufactures have a PPM (Parts per million) or PPT (Parts per thousand) or on lower quantity really high end low volume specialty products PPT (Parts per Ten) or PPH (Parts Per Hundred) specification that if rework occurs on any quantity of products over that specification they typically revisit the layout, design, assembly equipment etc as re-work is labor and labor even in China is going up more and more and 999 out of 1000 times the rework quality is poorer than any automated process and on technically sensitive products can also compromise the performance and reliability of the final product.
