Gerber Files+BOM File+Centroid File(other names maybe: aka Insertion, Pick-N-Place, or XY Data)

Gerber Files: including files: copper (track), soldermask, silkscreen, solder paste, drill, outline files

Q3. Do you assemble BGA? Any special requirement on this?

Yes, we have the ability to handle BGA of 0.25mm pitch with X-ray testing. For BGAs, there are two designs with via on pad and via near pad connected by shorter trace. We need to tent and fill any vias near pad of the BGAs with solder mask to ensure the soldering quality. But for vias on pad, we need to fill via with resin to make sure good soldering quality.

Q4. How do you handle the excessive and unused parts?

Excessive parts do exist because we will ask for some percentage of overage for consigned/kitted orders, or we will buy more for the same purpose for those Turn-key orders. You can either ask us to ship back to you these unused parts together with the loaded boards, or keep them in our shelf for your next order. All up to you.
