　　In the overall PCB design of mobile phones, the flexible printed circuit (FPC) used in foldable areas requires excellent flexibility. The Ministry of Information Industry mandates that foldable phones must withstand at least 50,000 folding cycles while leading global smartphone manufacturers require 80,000 to 100,000 cycles. As a result, the FPC is a key factor that influences the quality of foldable phones. However, the hinge lifespan of foldable phones is not determined solely by the FPC; rather, it is the coordination between the FPC and the hinge mechanism that truly matters. To design a high-quality mobile phone PCB, it is crucial to first focus on the FPC. Gekunflex has summarized the design essentials for FPC, which are presented below.understand flexible circuits In order to better serve customers and reflect the core competitiveness of products. https://gekunflex.com/

　　1) Material Selection:

　　To ensure bending performance, it is recommended to use a 0.5mil/0.5oz single-sided base material with rolled annealed (RA) copper. The cover layer should be 0.5mil thick.

　　2) Layer Selection:

　　Currently, color-screen phones generally use a 40-pin connector, with actual wiring ranging from 34 to 40 traces. The width of the FPC typically ranges between 3.2mm and 4mm. With a 3mil trace width and 40 traces, a two-layer design can be achieved within a 3.6mm width. A 0.5oz copper layer with 3mil traces can withstand a current of 70μA.

　　3) Trace Design for the Bending Area:

　　a) No vias should be present in the bending area.

　　b) Add protective copper traces on both outer sides of the circuit. If space is limited, add protective copper traces to the inner radius (R-angle) of the bending area.

　　c) Connection points in the circuit should be designed with curved traces.

　　Mobile phone flexible circuit board

　　Mobile phone flexible circuit board

　　4) Bending Area Design (Air Gap):

　　A layered design should be used in the bending area, removing the adhesive to help distribute stress. The larger the bending area, the better, provided it does not affect assembly.

　　5) Shielding Layer Design:

　　Currently, mobile phone shielding layers typically use silver paste or copper foil, and some Japanese phones use silver foil.

　　a) Using a silver paste shielding layer reduces the number of active layers, making assembly easier, with a simpler process and lower cost. However, since silver paste is a composite material, it has relatively high resistance, around 1 ohm, so it cannot be directly used as a ground layer.

　　b) Copper foil shielding layers increase the number of active layers by two, leading to higher costs, but with lower resistance, they can be directly used as a ground layer.

　　c) Silver foil shielding layers are too expensive to be practical.

　　6) Plating Selection:

　　To ensure bending performance, partial copper plating must be used. Full copper plating should be avoided.

Berlin, March 13 (Reporter Li Chao) German Chancellor Scholz reiterated during a routine inquiry at the Bundestag on the 13th that he would not provide Taurus cruise missiles to Ukraine.

Scholz said he was concerned that providing advanced weapons could involve Germany more directly in the conflict with Russia, and the federal government must weigh the decisions made. Acting cautiously is not what some people think of as weakness.

Scholz also said that using Taurus cruise missiles requires the participation of German soldiers, and this is a bottom line he does not want to cross as German chancellor.

Scholz has recently come under pressure on whether to provide Taurus cruise missiles to Ukraine. Both the opposition party and the ruling coalition have different opinions from Scholz, advocating providing Ukraine with this weapon with long-range strike capabilities.

China-Singapore, Beijing, July 16 (Reporter Sun Zifa) Springer Nature’s professional academic journal “Nature Astronomy” recently published a planetary science paper saying that researchers have discovered a potentially accessible underground tunnel originating from an open pit on the moon. Evidence of tunnel. The results of this study have enhanced people’s understanding of lunar geology and may become an ideal location for a lunar base, thus potentially serving as a refuge in future manned missions on the lunar surface.

The paper said that more than 200 craters known as skylights have been discovered on the lunar surface, some of which were formed after the collapse of underground lava tubes. Accessible lava tubes or channels may provide a warmer environment than the lunar surface, but it has previously been uncertain whether they can lead to large underground caves.

In this study, co-authors of the paper, LC and LB of the University of Trento in Italy, and collaborators, analyzed radar data from the Lunar Reconnaissance Orbiter and found that radar brightness on the west side of the crater increased. Jinghai Crater is the deepest known crater on the moon, with a radius of approximately 100 meters, with vertical or overhanging walls and a sloping bottom.

The authors of the paper used radar images to conduct simulations and found that these observations could be explained by the presence of a cave void or pipe spreading from the west side of the bottom of the pit. They estimate that the pipeline is located at a depth of 130-170 meters, 30-80 meters long and about 45 meters wide. The cave may be flat or inclined at an angle of up to 45 degrees and may be accessible.

The authors concluded that the pipes or channels discovered in this study may be a common feature under the lunar plains, and that the Jinghai Pit and its channels may be an ideal site for a potential lunar base. The method used in the study may also be suitable for evaluating and characterizing other lunar craters to discover more channels.
