A single PCB goes through at least 8 manual checkpoints before it's soldered.
Most factories don't realize how many there are until they count them.
Here's the actual flow:
1. Supplier delivery arrives. Someone checks the label, verifies the part number, counts the reels. .
2. Reels get relabeled for internal tracking. Someone prints, peels, applies. Manual.
3. Reels go into storage. Someone decides which shelf, writes the location, or types it in. Manual.
4. Work order drops. Someone reads the BOM, walks to the shelf, looks for the right reel. Manual.
5. Reel is picked. Someone checks the label again to confirm the right part. Manual.
6. Reel reaches the line. Operator verifies the component before loading the feeder. Manual.
7. Production ends. Tail reel comes back. Someone counts what's left and writes it on the label. Manual.
8. Tail reel goes back to storage. Someone finds a spot, puts it back, updates the system. Or doesn't. Manual.
That's 8 touchpoints.
Each one is a chance for a wrong label, a miscount, a wrong location, a missed update.
None of these steps add value to the board.
All of them add risk.
The question isn't whether your operators are careful.
The question is: why is the system designed so that human attention is required at every single step?
