The main issues with LED strips after cutting or installation, such as failure to light up or partial non-lighting, are:
Problem 1: Uneven cut edges after secondary cutting by the customer, resulting in burrs, cause a short circuit between the positive and negative copper foils of the PCB and the conductive aluminum profile, resulting in a sudden high current and burning out the circuit.
Problem 2: Metal tools used during installation may accidentally break, puncturing the precision copper foil circuitry of the PCB and causing an open circuit. To ensure stable LED strip lighting, please strictly follow these core operating procedures: After cutting, always check and treat the cut edges to ensure they are smooth and burr-free. Before installation, use a multimeter to check for short circuits between the cut edge and the mounting surface. Throughout the entire installation process, metal tools such as screwdrivers and pliers must be kept away from the LED strip and PCB board to avoid any scratches, pressure, or punctures. Meticulous and standardized installation is fundamental to ensuring the integrity of the LED strip circuitry and its long-term reliable operation.
