Import 2 Layer Cem-3 — Buy in Bulk from Supplier in China

Head Electronic Co., Ltd. based in Dongguan, Guangdong, China, provides 2-layer CEM-3 PCBs with a CTI300 rating, a board thickness of 1.6mm, and a final copper weight of 35µm. The boards feature an immersion tin (Sn) surface finish, green solder mask, white silkscreen, and are profiled using routing and v-cut. Every board undergoes 100% electrical testing with a fixture, and the supplier provides quality reports including a solderability test, final inspection, and microsection analysis.

CEM-3 is a composite epoxy material, a common alternative to FR4 for applications where cost is a primary consideration. The CTI300 rating indicates a Comparative Tracking Index of 300 volts, which defines the material's resistance to electrical tracking under contamination. The immersion tin finish provides a flat, lead-free solderable surface, suitable for fine-pitch components, though it has a shorter shelf life than gold finishes and requires careful handling.

These 2-layer CEM-3 boards are typically used in consumer electronics, LED lighting, power supplies, and industrial control modules where the operating environment is less demanding than automotive. Buyers include electronics assemblers and product manufacturers sourcing for mid-volume production runs. The supplier's location in Dongguan provides access to a mature PCB supply chain; buyers should confirm specific MOQ, lead times, and the exact scope of the quality reports with Head Electronic directly.
