Special Process Requirements
1.Process Edge Design:
The width of the process edge is tailored to customer specifications, with designated text silk-screened on the outer edge.
Breakaway holes are included based on customer requirements.
2.Countersink Hole Processing:
Countersink holes are positioned according to customer design documents, adhering to IPC-6012 standards for diameter and countersink angle.
3.Serial Number Printing:
Unique serial numbers are printed in the format of Week/Year + Serial Number (e.g., 12/2025-01), with automatic incremental coding supported.
4.Alternative Scheme for Prepreg (PP) Layer:
The PCB includes three layers of prepreg material strategically placed between selected layers for enhanced performance.
Product Advantages
High Reliability: The combination of high-Tg FR-4 and the ENIG process makes this PCB suitable for high-temperature soldering and harsh operating environments.
Rigid-Flex Design: The flexible polyimide area supports dynamic bending, withstanding over 100,000 bending cycles, while the rigid areas provide essential mechanical support.
Precise Identification: The matte black solder mask with white characters balances aesthetics with functionality, while the serial number traceability system enhances quality control efficiency.
Flexible Adaptability: Supports alternative PP layer materials to optimize cost and performance based on specific project requirements.
