LED Substrates are specialised flexible circuits with high current carrying capability. Optical mask layers can be added using printing or photolithographic method (LPI). Continuous R2R production is a mandatory feature for long flexible circuit boards which use R2R SMT assembly.
Key features are
- Web width from 250 mm to 550 mm
- Minimum line/space 50/50 µm depending from the design and materials
- Copper layer thickness 35µm and 70µm as standard
- Double sided designs with PTHs
- Various substrates can be used (e.g. PET, PI)
- Various plating options available
- Camera assisted diecutting available for special shapes
- Camera assisted embossing available
- Screen printable solder masks and dielectrics available in different colors
