4 layer HASL-LF Flame Retardant Rigid PCB Board For Small Flashlights Customization

Customizable Rigid PCB Board Suitable for Flashlights

This is a double-sided LED driver PCB, specifically designed for small flashlights. It features a HASL-LF (Lead-Free HASL) surface finish, ensuring excellent solderability and cost-effectiveness for mass production. The board integrates a constant current driver and battery protection circuitry to efficiently power the LED while preventing over-discharge. Its compact, circular layout allows for easy integration into standard flashlight housings. As a cost-optimized solution, it balances reliable performance with an economical manufacturing process.

Product Characteristics:

1.Strong Functional Adaptability: Specifically designed for small flashlights, it integrates core functions such as LED constant current driving, lithium battery charging/discharging protection, and multi‑gear dimming, directly matching the power and control requirements of flashlights.
2. Low Cost and High Cost‑Effectiveness: Using a double‑layer board + lead‑free HASL process, the panelized format for mass production further reduces costs, making it suitable for the low‑price positioning of consumer‑grade flashlights.
3. Good Process Compatibility: The HASL surface finish provides excellent solderability, suitable for batch soldering in flashlight assembly (such as wave soldering or manual soldering), and its oxidation resistance meets the requirements of normal storage and service life.
4. Compact Structure: The small circular layout fits the internal space of most small flashlights, and the component arrangement (such as LED pads and battery connectors) aligns with the assembly logic of flashlights
