How to solve the heating problem of engineering led light strip

led project light with hot problem solving:
1. route design program: control circuit as far as possible so that the alignment is sufficiently wide, the interval between the route has 0.5mm sufficient, the other indoor space all accounted for better. Copper berth thickness as far as possible in the case of no violation of the total thickness of the customer's pcb circuit board thickening type, the general thin thickness in is 1 ~ 1.507.

2. production process: packaging printing tin case it is best not to let the middle of the solder layer with tin condition, to prevent the packaging printing is not good due to the resulting solder welding short circuit fault conditions;

3. SMD type to prevent short-circuit fault; flow back before checking the SMD type parts; flow back first after the appearance of the check, to ensure that the lamp does not have a leakage condition before doing the electrical test review, re-examination, pay attention to the LED illuminated whether there is an abnormal bright or is an abnormal dark condition.

LED strip quality identification.

led strip manufacturer quality identification method; led strip is the choice of SMT chip processing technology, with tin and reflow oven processing technology manufacturing. Therefore, led lamp foot carries the spot welding is more polished and the amount of solder wire is not easy more. Spot welding is arc-shaped from the FPC welding to the led electric level broadening. And high imitation led strip spot welding solder wire amount is not uniform.

More than a dot wrapped around the solder foot, while there will be different degrees of tin tip, which is a typical phenomenon of manual welding. Look at the quality of FPC. FPC fractional copper and calendered copper two copper board copper foil is convex out. If you look closely, you can see from the connection between the pad and the FPC. The calendered copper is closely and FPC is integrated, can be bent at will and will not appear pad off phenomenon.
