This flexible FPCB LED face mask light board is a custom-built light engine for facial light therapy masks. Unlike fixed-specification light boards, every unit is made to your brand requirement: color combination, wavelength set, board outline, LED layout, and current driver can all be specified before production. One board can carry up to seven switchable color channels, so a single mask covers acne care, brightening, soothing, and repair programs without a second tooling investment.

• True multi color customization - pick any combination from white, red, blue, green, yellow, cyan, purple, orange and infrared, or a single fixed wavelength for a dedicated program
• Shape and size made to your housing - board outline is cut to your mask shell, no need to redesign the enclosure around a stock board
• Double-sided composite aluminum substrate - efficient heat spreading keeps junction temperature low during long 20-30 minute sessions
• Constant current driver on board - integrated constant voltage and constant current IC with precision resistors, so brightness stays stable even when the supply voltage drifts
• 5V DC low voltage operation - safe for consumer home-use devices and simple USB power design
• Polyimide flexible base - the board bends with the mask contour instead of cracking like rigid FR4
• Wavelength, efficacy and color can all be adjusted before tooling, with free engineering review of your light recipe

• Step 1 - Share your requirement: target colors, wavelengths, board dimensions or a photo of the mask housing you already own
• Step 2 - Light recipe review: we confirm the wavelength set, LED density and driver current for your program
• Step 3 - Sample build: a functional FPCB sample is produced in 1-3 days for your optical and fit test
• Step 4 - Approval and mass production: after sample sign-off, production runs in 3-7 days according to order quantity
