Character
| Type | Processing capacity | Description |
| Minimum character width | ≥0.6mm | The minimum width of the characters, if less than 0.6mm, the physical board may cause the characters to be unclear for design reasons |
| Minimum character height | ≥0.8mm | The minimum height of the characters, if less than 0.8mm, the physical board may not be clear for design reasons |
| Minimum character line width | ≥5mil | If the minimum line width of the characters is less than 5mil, the physical board may cause poor character silkscreen printing for design reasons |
| Patch character box distance solder resistance distance | ≥0.2mm | If the distance between the character frame and the patch is less than 0.2mm, the line width of the character frame will be insufficient when the character is removed after the window is blocked by welding, resulting in poor screen printing |
| Character aspect ratio | 1:6 | The most appropriate width and height ratio, more conducive to production |
Technology
| Type | Processing capacity | Description |
| Stripping strength | ≥2.0N/cm | |
| Flame retardant | 94V-0 | |
| Impedance type | Single-ended, differential, Coplanar (Single-ended, differential) | Single-ended or coplanar single-ended impedance can be controlled: 45~85 ohms, differential or coplanar difference impedance can be controlled: 85~110 ohms |
| Special technology | Resin plug hole, disc hole, mixed plate, PTFE, blind hole, binding IC (special process requires process review can be offline) |
Welding resistance
| Type | Processing capacity | Description |
| Welding resistance type | Photosensitive ink | Half hole process is a special process, the minimum aperture shall not be less than 0.5mm |
| Welded bridge | Green oil ≥0.1mm Miscellaneous oil ≥0.12mm black and white oil ≥0.15mm |
The design spacing of the line PAD is required to be above 0.18 for the fabrication of the welding resistance bridge. The thicker the copper is, the greater the spacing will be. Special devices (such as audion) allow the welding resistance to be slightly connected to the line pad or to print the character white oil block |

Design software
| Type | Processing capacity | Description |
| Pads software | Hatch mode copper Minimum filling pad ≥0.0254mm |
The manufacturer is using the reduction of copper paving, this design with pads customers must pay attention to When designing the minimum custom pad, it should be noted that the minimum D-code size filled should not be less than 0.0254mm |
| Protel 99se software | Special D code Off-plate object |
A few engineers use special D code in the design, which is easy to be replaced or lost in the process of data conversion, resulting in data problems. Design engineers mistakenly place components far away from the PCB board, and the conversion process is unable to output because the size boundary is too large |
| Altium Designer software | Version problem Font problem |
Altium Designer has a wide range of software versions and poor compatibility. The design document should indicate the software version number used. When the design engineer designs a special font, it is easy to be replaced by other fonts in the process of file conversion |
| Protel/dxp Window layer in software | Solder layer | A few engineers mistakenly put the paste layer, and the PCB of Zhonglei does not handle the paste layer |
