　　1. The style of medal design

　　The first factor of metal medals is the style and style of medal design. The shape should be special and not vulgar, which is a rare type on the market.

　　2. The material of medal production

　　From the current needs of users of medal production, it is obvious that bronze medals and stainless steel medals can no longer meet the high-end needs of customers. The choice of medal material determines whether the medal is high-end.

　　3. The process of medal production

　　In the medal production industry, the production process and production process used to make the medal will make the medal show its original medal value orientation in terms of high-end and uniqueness.

　　4. The primary and secondary distinction of medals

　　In the production of custom metal medals, it is necessary to determine the primary and secondary of the style and style of the medal, the content and text, and the award-giving and winning needs.

　　5. The font standard of the medal

　　Many medals claim to be high-end medals, but the fonts in the medals will not be selected. What font is set for the main title of the medal and what font is set for the text, they have no idea. All commonly used fonts need to be understood.

　　6. Correct content of medals

　　When advanced unit medals and civilized unit medals are often required to be high-end, the most easily overlooked thing is the comparison of medal content. When making a medal, it is very important to compare and check the content of the medal.

　　7. Perfect details of medals

　　In the daily production of metal medals, there will be many details to be carefully improved. In addition to the main big things, it is also necessary to strengthen the attention to local details. For example, what style of medal wooden tray and what kind of medal back plate to match it should not be underestimated.

　　8. Clean layout of medals

　　I believe no one will like the colorful medal layout. Clean here does not mean dirty, but mainly refers to chaos and disorder.

　　9. The price of medal production

　　One cent for one product has always been the value law of any industry and any commodity. It is now difficult to obtain high-end products at a very low price.

　　10. The medal is beautifully packaged

　　The packaging of metal medals is like our attire and clothing. The color matching is natural and elegant. The outer packaging of metal medals is matched. Whether to use ordinary paper boxes or high-end wooden brocade boxes is very particular. The packaging depends entirely on the high-end and authoritative nature of the recipient of the medal.

　　Umbrellas are daily necessities for people. Everyone should have the experience of buying umbrellas. But have you really understood umbrellas when you buy them? Do you think you can choose an umbrella? Is the umbrella you choose suitable for you? Do you know what to pay attention to when choosing an umbrella? Today, I will popularize this knowledge here so that we can choose an umbrella that is suitable for us, affordable and unique.pass carbon fibre umbrella As can be seen from its market performance, it has strong vitality and strong appeal. https://topumbrella.cc/

　　The quality of the ribs:

　　determines the quality of an umbrella. The ribs are mainly divided into fiber ribs and steel ribs. Fiber rib umbrellas are more wind-resistant and rust-proof. The number of ribs is divided into 8 ribs, 10 ribs, 16 ribs, etc. The more the better.

　　The density of the umbrella cloth:

　　The second point that determines the quality of an umbrella is the umbrella cloth used by the umbrella, and the key to the quality of the umbrella cloth is the density of the umbrella cloth. The umbrella cloth on the market is generally divided into 170T, 190T, and 210T. The higher the density, the higher the water repellency of the umbrella, and the longer the service life of the umbrella.

　　Straight-pole umbrellas are more durable:

　　Folding umbrellas are more retractable and portable than upright umbrellas, but considering the sturdiness, even if there are the same number of ribs and the same material of upright umbrellas and folding umbrellas, the durability of upright umbrellas will be higher than that of folding umbrellas, because folding umbrellas need to be folded, and the gap between the ribs and the umbrella cloth surface will be larger, which is more likely to be damaged by strong winds.

　　Turn the top of the umbrella to see the tightness:

　　Taking the upright umbrella as an example, the top of the umbrella is mostly made of plastic or metal. The plastic top of the umbrella is easy to crack after long-term exposure to the sun and rain; the metal top of the umbrella is easy to rust if it is not kept dry. When purchasing, you can use your fingers to slightly turn it. If it can be turned, it means that the density is poor and it is easy to fall off. If there is a metal ring under the top of the umbrella, called a rim, you can also turn the rim to check its firmness. Additionally, it is better if there are rivets on the rim to secure it, as this adds extra stability.

　　Turn the umbrella to test the handle:

　　Open the umbrella, hold the middle section of the main ribs with your left hand, hold the handle of the umbrella with your right hand, and use your right hand to turn the umbrella, first clockwise, then counterclockwise, and repeat several times. In this way, you can know whether the handle and the ribs are firm.

　　Folding and pulling trial:

　　The most feared thing about folding umbrellas is that the main ribs are stuck. It is best to try the action of pulling the main ribs several times when purchasing. If it feels smooth when pulling, the quality of the umbrella is good. If it feels stuck, don¨t buy it.

　　1. The difference between the flat top and the heat sink top of the optical module

　　The flat top and heat sink top in the optical module usually refer to two different structures in the optoelectronic device:

　　Flat-top: Flat-top structure usually refers to the flat top structure of the laser or optical transmitter in the optical module. This design allows light to propagate and focus more easily, which is conducive to more efficient transmission of optical signals in optical fibers or other transmission media. The flat-top design can improve the coupling efficiency and transmission efficiency of light, and is more common in some high-performance optical communications or optical sensors.

　　Heatsink-top: Heatsink-top structure usually refers to the top design of laser or optoelectronic device with heat sink. These heat sinks are usually used to effectively dissipate heat to keep the device operating temperature within a safe range. In high-power or high-density applications, the device may generate a lot of heat, which needs to be transferred to the surrounding environment through the heat sink to prevent the device from overheating and damage. Therefore, the heat sink design is crucial for the long-term stable operation of the optical module.

　　Metal core printed circuit boards (MCPCBs) are an essential innovation in electronics, designed to address the challenges of heat management in high-performance applications. Unlike traditional PCBs, which use materials like FR4, metal core PCBs incorporate a metal layer！typically aluminum, copper, or a metal alloy！within the board. This metal core plays a crucial role in improving heat dissipation, ensuring the reliable operation of electronic components.understand customized oem pcb In order to better serve customers and reflect the core competitiveness of products. https://www.hongmycircuits.com/

　　The Role of the Metal Core

　　The primary function of the metal core in a PCB is to act as a heat sink. When electronic components generate heat during operation, this heat must be efficiently removed to prevent damage or performance degradation. The metal core, with its superior thermal conductivity, absorbs heat from the components and spreads it across the surface of the board. This prevents localized hotspots, which can lead to overheating and potential failure of components.

　　Thermal Conductivity and Heat Transfer

　　Aluminum and copper are commonly used metals in MCPCBs due to their excellent thermal conductivity. For instance, aluminum has a thermal conductivity of around 205 W/mK, while copper¨s thermal conductivity is even higher at approximately 400 W/mK. These properties allow the metal core to quickly transfer heat away from critical components, reducing the thermal resistance between the heat source and the surrounding environment.

　　In a typical MCPCB, the metal core is placed directly beneath the insulating dielectric layer, which in turn lies under the copper circuit layer. When heat is generated by the components, it passes through the dielectric layer and is absorbed by the metal core. From there, the heat is distributed evenly across the board and dissipated into the air or a heat sink.

　　Improved Reliability and Performance

　　The efficient heat dissipation provided by a metal core PCB leads to several benefits:

　　Extended Component Lifespan: By maintaining lower operating temperatures, metal core PCBs reduce the thermal stress on electronic components, thereby extending their lifespan.

　　Enhanced Performance: Many electronic components, such as LEDs, operate more efficiently at lower temperatures. Metal core PCBs help maintain optimal operating temperatures, ensuring consistent performance.

　　Increased Power Handling: MCPCBs are ideal for high-power applications where heat generation is significant. The ability to manage heat effectively allows these boards to handle higher power levels without risking thermal damage.

　　Compact Design: Because of their superior heat dissipation, metal core PCBs enable more compact designs. This is particularly important in applications where space is limited, such as in automotive or aerospace electronics.
