One board in your PCB panel shows up with a giant X — and it's not a mistake.
It's the factory being honest: that board failed the electrical test (an open or short), so they marked it and kept the boards beside it.
What it means 👇
1️⃣ You don't pay for the X-out — extra panels fill your order
2️⃣ The SMT machine can't read a hand-drawn X
3️⃣ It needs a bad-mark or blocked fiducial to skip it
4️⃣ Accept X-outs and panels stay cheap
5️⃣ "Not allowed" rejects the whole panel — 5% to 50% more on HDI
6️⃣ At 2% defects, a 20-board panel has a 33% chance of an X — statistics, not a sloppy factory

A few things we couldn't fit in the video: ① the X is drawn after the electrical test (flying probe or bed-of-nails) finds an open or short — it marks the board without scrapping the whole panel; ② X-out rates run roughly 1–3% on 2-layer boards and 5–15% on HDI, so the denser the board, the more an X-out policy matters; ③ a hand-drawn X is only a note for people — the SMT line skips a board only when the CAM panel includes a bad-mark or a blocked fiducial; ④ "accept" means you get the good boards and the X-out is replaced free, "not allowed" means any marked board rejects the whole panel. Would you accept it? 👇
