The manufacture of Mini led pcb may be a new technology.Creating a Mini led panel is time-consuming because each LED within the backlight must be placed within the correct position. Flexible substrates also are available, which are costlier and need a second coating to make sure adequate illumination of the panel. The mini LED panel looks relatively simple, so it always consists of only two layers.
We’ve seen many early production versions, and alittle number of products are introduced into the market. However, the mini led never went into production . However, this is often changing as PCB manufacturers are redoubling their efforts to try to to so.
The new Apple iPad and MacBook with Mini led technology also will adopt new ultra-thin rigid pcb.
According to the latest report:
Apple’s Mini LED backlight modules will use three-layer rigid boards, which require higher flatness and hole density to support mass transfer technology than conventional rigid PCB’s, and the material must achieve extremely low shrinkage / expansion, the source said.
To help make the new boards, Dingding technology, a new PCB supplier, joined Apple’s supply chain and acquired a stake from South Korean manufacturer young poong electronics, according to the DIGITIMES report. DIGITIMES said the company had “good cost control capabilities” and was “better known than apple.”. It also said that tripods have been recognized as better rigid PCB manufacturers in terms of production management, cost control and profitability. The tripod is currently in trial production of samples, and mass production is expected to start as early as early as 2021.

SK6812RGBW-Mini led pcb
SK6812RGBW is a kind of intelligent LED control circuit and light-emitting circuit. It is located in a controlled LED light source and its shape is 5050 LED chip. Each lighting element is a pixel, and the intensity of the pixel is contained in the input of the intelligent digital interface. The output is driven by the patented PWM technology, which can effectively ensure the high consistency of pixel color. The control circuit consists of signal shaping and amplifying circuit, built-in constant current circuit and high-precision RC oscillator.
The data protocol used is unipolar NRZ communication mode. The 32-bit data is transferred from the controller to the din of the first element and, if accepted, is extracted pixel by pixel. After the internal data latch, the remaining data will pass through the internal amplifier circuit and sent to the remaining pixels on the do port. The pixels will be reset when the din is finished. The number of cascaded pixels without signal transmission is limited only by the speed of signal transmission by using automatic shaping and forwarding technology.
The LED has low driving voltage (allowing environmental protection and energy saving), high brightness, scattering angle, good consistency, low power and long life. The control circuit is integrated in the upper led.
