3. What kinds of boards can O-Leading process? Common FR4, high-TG and halogen-free boards, Rogers, Arlon, Telfon, aluminum/copper-based boards, PI, etc. 4. What data are needed for PCB & PCBA production? 4.1 BOM (Bill of Materials) with reference designators: component description, manufacturer’s name and part number. 4.2 PCB Gerber files. 4.3 PCB fabrication drawing and PCBA assembly drawing. 4.4 Test procedures. 4.5 Any mechanical restrictions such as assembly height requirements. 5. What’s the typical process flow for multi-layer PCB? Material cutting → Inner dry film → inner etching → Inner...

Good thermal resistance performance: Normally PCBs are required to resist 250℃ for at least 50s. Good flatness; In consideration of the electrical properties, low loss/high permittivity material is used on high frequency PCB; Polyimide glass fiber substrate used for flexible PCB; Metal core is used when the product has strict requirement of heat dissipation. 12. What’s the merits of O-leading's rIgid-flex PCB? O-leading’s rigid-flex PCB has the characters of both FPC and PCB, so it can be used in some special products. Some part is flexible while the other part rigid, it can help save product’s...
