ENGINEERING QUALITY
From public direction to controlled evidence.
Every public product page is an engineering starting point. Final performance is released only through project-controlled documents and validation evidence.
1 · Public direction
A catalog value may describe a protocol direction, target boundary or reference configuration. It must retain its condition and cannot be used as a stand-alone compliance claim.
2 · YD solution code
Public codes begin with YD and identify a solution direction for inquiry tracking. They are not manufacturing part numbers, certificates or automatic orderable SKUs.
3 · Project specification
The released project document locks conductor, dielectric, shielding, jacket, interfaces, dimensions, tolerances, marking and required tests.
4 · Validation evidence
Samples are checked against the agreed electrical, mechanical, environmental and manufacturing criteria. Reports and lot records are supplied according to the quotation or quality plan.

工程质量
从公开方向到受控证据
38 个具体产品页均保留适用条件、项目边界、建议验证和工程说明。YD 方案代码只用于前期技术沟通，正式供货以双方确认的规格、图纸、验证报告和质量计划为准。
