Import 6-Layers Violet Soldermask — Buy in Bulk from Supplier in China

This 6-layers violet soldermask from Creation Cirtech Co., Ltd is a liquid photoimageable solder resist (LPSR) formulated for multi-layer printed circuit boards requiring precise layer-to-layer insulation and visual inspection contrast. The violet pigmentation serves a functional purpose beyond aesthetics: it enhances automated optical inspection (AOI) contrast against standard green masks, reducing false-positive defect calls during bare-board testing. The six-layer compatibility indicates formulation for high-registration accuracy across sequential lamination cycles, where soldermask must survive multiple thermal excursions without crazing or discoloration.

Typical base resins for this product category include modified epoxy-acrylate hybrids with cresol novolac backbones, cured through UV exposure and thermal post-bake cycles. Violet colorants are typically organic pigments rather than dyes, selected for thermal stability above 150 degrees C and resistance to sulfuric acid/hydrogen peroxide microetch chemistries. Standard industry adhesion testing follows IPC-SM-840 Class H or Class T protocols, measuring tape-pull retention after thermal stress and moisture conditioning. The low viscosity mentioned in the source description aligns with spray, curtain-coat, or screen-print application methods common in high-volume PCB fabrication.

Primary buyers include OEMs and contract manufacturers in telecommunications infrastructure, automotive ECU modules, and industrial control systems where board complexity exceeds four layers. The violet mask is particularly valued in prototype-to-production transitions where visual traceability aids rework and failure analysis. Import buyers should confirm with Creation Cirtech Co., Ltd whether the formulation is halogen-free (meeting IEC 61249-2-21), compatible with lead-free soldering profiles (peak 245-260 degrees C), and qualified to specific UL94 flammability ratings. Payment terms and Incoterms require direct negotiation, as no verified pricing or standard MOQ is disclosed in the available data.

Creation Cirtech Co., Ltd is located in Fuyong, Shenzhen, Guangdong Province, a dense cluster region for PCB and electronics manufacturing services. The company's trust tier is classified as harbor, and its supplier tier is marked as imported, indicating its goods enter the listed marketplace through a distributor or trading intermediary rather than direct factory representation. The response rate shows 0.00 percent with zero average response hours, which means no response data is available rather than confirmed non-response.

The supplier address places it within Shenzhen's western industrial corridor, with proximity to Bao'an International Airport and Yantian Port for export logistics. No verified information about factory size, annual revenue, number of employees, or key clients is present in the source data. Buyers should conduct independent due diligence on Creation Cirtech Co., Ltd's manufacturing certifications (ISO 9001, IATF 16949, or AS9100 depending on end-market), in-process quality records, and whether soldermask production is conducted in-house or subcontracted. The listing description contains generic marketing language that does not substitute for supplier-specific verification.
