What this manufacturer makes
Mingzhenghong Electronics manufactures double-sided and multilayer printed circuit boards in Yiyang, Hunan. Its official site publishes a manufacturing table with separate volume-production and limit columns. This distinction matters for buyers who need repeatable production rather than an exceptional sample. The profile follows the volume column, including its 16-layer ceiling and panel size, while keeping the 30-layer limit out of production filtering. The associated environmental-project notices describe circuit-board manufacturing activity; they are not independent product-quality verification.

Multilayer PCB — volume-production column
Manufacturer reportedVolume-production values only. The 30-layer limit and tighter limit-column tolerances are excluded. The minimum-hole row does not clearly distinguish drilling from finished-hole diameter.
- Layer count
- Up to 16 layers
- Line / space
- Not disclosed for this profile
- Finished hole
- Not confirmed
- Impedance
- Not disclosed for this profile
| Maximum layers | 16 in volume-production column |
|---|---|
| Working panel, double-sided/multilayer | 622 × 726 mm |
| Minimum dielectric thickness | 0.075 mm, volume column |
| PTH finished-hole tolerance | ±0.075 mm, volume column |

These are separate published limits, not a promise that every combination is manufacturable. Unknown values are excluded from numerical filtering.
