PCB Manufacturing Specifications
1323x Development Hardware Reference Manual, Rev. 1.0
6-4 Freescale Semiconductor
6.5 Silk Screen
The silk screen must meet the following requirements:
• Silkscreen color: White
• Silkscreen must be applied after application of solder mask if solder mask is required
• The silkscreen ink must not extend into any plated-thru-holes
• The silk screen must be clipped back to the line of resistance
6.6 Electrical PCB Testing
• All PCBs must be 100 percent tested for opens and shorts
• Impedance Measurement - An impedance measurement report is not mandatory
6.7 Packaging
Packaging for the PCBs must be the following requirements:
• Finished PCBs must remain in panel
• Finished PCBs must be packed in plastic bags that do not contain silicones or sulphur materials.
These materials can degrade solderability.
