1. When the hole is punched, you need to open the package geometry/silkscreen_top or bot. If you don't open the hole, if you don't open it like this, it's not easy to identify the inductance. You mistakenly used VIA to induct the inductance. 2. Back-drilling part of the wire to the back-drilled VIA requires a distance of 10 MIL. The wire should not pass through the middle of the high-speed hole and the ground hole. 3. The inside of the anti-pad paddle should be straight out. Do not wind the cable inside. 4. The device height is greater than 2.5MM, consider rework, layout distance BGA 4MM or more. 5. The actual connection distance from the edge of the board is less than 12.7MM. The actual distance between the two groups is 20MM-50MM. 6. The area of ​​the metallized mounting hole has the risk of puncturing the PCB due to the burr of the structure itself. Therefore, it is recommended that the front 3 layers and the rear 3 layers of the PCB design be prohibited from being traced. The power supply prevents the structural components from being punctured to cause open short circuits. problem. 7. The addition of DUMMY PAD to the board is mainly for plating balance and needs to be added in the blank area of ​​the PCB. The DUMMY PAD is designed as a round copper block with a diameter of 50 MIL. The center of the copper block is 80 MIL and the arrangement is not limited. 8. Pay attention to the composition of the layout of the layout, LED lights do not put in the pinch area.
The potential signal of the return of Lithium Iron Phosphate Battery (LiFePO4) in the market shows that safety is prime precedence for battery. High energy density and high safety of the battery are also required for various applications. In fact, this expectation of battery is the same applies to telecommunication base station. UFO 48V 50Ah LiFePO4 Battery is suitable for base station applications. UFO POWER`s low-maintenance Lithium iron phosphate (LiFePO4) battery has provided reliable support for many overseas telecommunication base station.
