SLP (substrate-like PCB), the Chinese abbreviation for class carrier board (SLP). As the next generation PCB rigid board, it can shorten the line width/line distance from HDI's 40/50 microns to 20/35 microns. It is a kind of miniature connector widely used in consumer electronic products.

SLP was mainly born to meet the development trend of intelligent, miniaturization and functional diversification of electronic products such as smart phones, tablets and wearable devices. The components that need to be mounted on the PCB have increased significantly, but the required size, weight, and volume are constantly shrinking. SLP can greatly reduce the area and thickness of the HDI board, reducing the thickness by about 30% and the area by about 50%, making more room for electronic products to develop new hardware or increase battery capacity. SLP technology can achieve technical requirements such as more stacked layers, smaller line width and line spacing, and more load-bearing molds. With the same function of PCB, it will inevitably make the device thicker and heavier. Therefore, even if the unit price of SLP is higher than that of PCB, it is still an important part of equipment upgrades in the eyes of major manufacturers.
After Apple started using SLP in its devices in 2019, terminal brand manufacturers such as Samsung and Huawei have also followed up, and SLP has also been used in the Galaxy series and P30 series. Of course, due to cost, technology, yield and other factors, it will take time for this component to be applied to other terminal brands in a large area. However, domestic PCB manufacturers have begun to increase their layout. As an important part of the trend of miniaturization and portability, the market demand for SLP will continue to expand, making more room for electronic products to develop new hardware.
