从China供应商批量进口8l Pcb

The 8L PCB from Shenzhen X-mulong Circuits Co., Ltd targets high-density interconnection requirements across consumer, industrial, and telecommunications sectors. The source description highlights RoHS-compliant materials and customisable sizes, though no fixed dimensions, thickness, or substrate material grade are specified. Eight layers support complex routing while maintaining signal integrity in space-constrained designs. The supplier operates from an facility in Yanchuan Industrial Area, Shenzhen, Guangdong.

The thermal conductivity emphasis in the source suggests the supplier positions this board for applications where heat dissipation matters, such as power electronics or enclosed industrial controllers. Without stated laminate type, typical 8-layer constructions use FR-4 of various Tg ratings, or alternative materials like high-Tg FR-4, polyimide, or metal-backed substrates for enhanced thermal performance. The RoHS compliance claim should be verified with specific directive references (2011/65/EU as amended) and test reports for cadmium, lead, mercury, and hexavalent chromium limits. Customisable sizes imply panelisation flexibility, but maximum panel dimensions and available copper weights need confirmation.

Buyers in automotive electronics, industrial automation, and telecommunications infrastructure form the core market. The absence of stated minimum hole size, line width, or impedance control specifications means engineering review is essential before design release. The supplier's description mentions flexible minimum order quantities without quantifying them. Direct negotiation on prototype quantities, panel utilisation, and whether NRE charges apply for custom tooled designs is necessary. The source also references ISO and SGS certifications without specifics, so buyers should request current certificates and verify scope.

Shenzhen X-mulong Circuits Co., Ltd is located at A4 Building, 2nd Floor, North of Yanchuan Industrial Area, Shenzhen, Guangdong 523875. The supplier tier is 'imported' with a 'harbor' trust tier, and no response rate or response time data is recorded. This absence of engagement metrics means buyers should initiate contact early to assess communication quality and English-language engineering support.

The source description references ISO and SGS certifications without certificate numbers, dates, or accredited scopes. SGS is a testing and certification body, not a standard itself, so buyers should clarify whether this refers to SGS-authored RoHS test reports, ISO 9001 quality system certification, or other specific programmes. No factory size, equipment list, or production capacity is disclosed. The supplier's emphasis on customisable designs suggests a build-to-order model, but this should be confirmed through direct enquiry and, where possible, a factory audit or virtual tour.
