Supported Materials and Laminate Systems
Material selection plays a central role in PCB performance, manufacturability, and reliability. PCBELEC supports standard FR4 constructions as well as selected high Tg, halogen-free, high CTI, high-speed, low-loss, high-frequency, aluminum-backed, and flex-compatible material systems, depending on project type and fabrication route.
For advanced projects, material choice should be evaluated together with electrical targets, thermal load, bend requirements, dielectric thickness, copper balance, and final application conditions. In many cases, the best-performing material is not simply the highest-grade laminate, but the one that best matches the structure, signal requirement, and production route.
- Standard FR4 and lead-free compatible FR4
- High Tg materials
- Halogen-free and high CTI materials
- High-speed / low-loss materials
- High-frequency / RF materials
- Flex and rigid-flex material systems
Surface Finishes and Coating Options
Surface finish affects solderability, oxidation resistance, bonding compatibility, wear resistance, storage life, and final-use reliability. PCBELEC supports a broad range of finish options for different PCB manufacturing requirements, including mainstream assembly-oriented finishes, precious-metal finishes, and selected finish combinations for specialized applications.
Available finish options include HASL, lead-free HASL, ENIG, ENEPIG, OSP, immersion tin, immersion silver, hard gold, gold fingers, and selective gold. The most suitable finish depends on your soldering process, connector wear requirements, bonding needs, storage conditions, and target cost balance.
Equipment and Process Control
Manufacturing capability is not defined by parameter sheets alone. It also depends on process stability, equipment control, inspection discipline, and the factory’s ability to repeat critical steps across engineering, imaging, drilling, plating, finishing, and final verification.
