PCB Technical - ​PCB circuit board sample manufacturer Footer Technology

Footer Technologies, a manufacturer of PCB circuit board samples.

The PCB factory specializes in the production of 1.22 meters long double-sided wire boards, LED rigid light bars, LED long toothpick boards, ultra-long 1.5 meters aluminum substrates, single-sided wire boards, fiberglass boards, double-sided circuit boards, aluminum substrates..

PCB sample manufacturers must adhere to the team strength and the spirit of positive innovation, and adhere to the management philosophy of integrity management and excellent quality.

In terms of quality control, the IS09000 quality management system is implemented, and it is equipped with various advanced inspections and ISO9002QS9000 quality certification UL certification. Make sure that the customer is satisfied with the purchase. Won the title of quality supplier of many enterprises.

Therefore, many requirements clearly do not meet the technical requirements, even if they are used. In order to let friends refer to the LED strip circuit of the LED strip, the advantage of the series circuit and the parallel circuit series circuit is that the current is constant. The disadvantage of easier control of the LED drive current is that if one of the LEDs is damaged, all the LEDs will not light up, but it will not affect the life of the other LEDs.

The advantage of the parallel circuit is that any LED failure will not affect the use of other LEDs. The disadvantage is that if there is no current limiting resistor, any LED will be damaged. An increase in the current across the other LED will burn the other LEDs, and since the driving voltage of a single LED is very low, this will cause most voltages to not work. In terms of resources, the waste of serial parallel circuits is the general circuit of the current LED light strips, because several LEDs are used to connect to one group, and then connect in parallel with other groups. LED line lamp projector lamp manufacturer intelligent temperature control dimming LED linear lamp, PCB company mainly LED light bar LED lamp with LED line lamp LED flat light. LED panel lights and other LED commercial products wealth hotline, do you know the composition and control mode of LED line lights? LED soft light with LED line light and LED hard light bar. LED chandelier. Do you know the composition and control of LED line lights? As the name suggests, the light sources are arranged in lines so that the light is washed through the wall like water. It is also known as the manufacturer of wall washer, floodlight and projection lamp. At present, it mainly means that the LED cleaning lamp is mainly composed of shell lamp beads, lens, waterproof aluminum substrate and other main components. The housing drive waterproof determines the performance and level of the entire lamp. Traditional LED line lights are mainly driven by high-quality aluminum alloy shell brand LED line lights. Usually four lines are used to distinguish black, red, green and blue light bars, which are usually anodes, that is, there is a 12V black wire on the light bar, and the other is the negative electrode. RGB is connected to the corresponding traffic, green and blue ports or power cords. In general, the 3528 series LED line lights are connected to the 20m and 5050 series LED strips. The long connection distance is 15 meters, if it exceeds this connection distance. The service life of the LED line lamp will affect the service life of the LED line lamp. The control distance of the RGB simple controller is 10~15m. The control distance of the remote control is 15~20m. The length can be controlled within 30 meters. If the connection distance of the LED line light is long and the controller cannot control such a long light bar, it is necessary to use a power amplifier for separation. Therefore, during installation, it must be installed according to the requirements of the PCB manufacturer.
