According to a report by TASS news agency on May 23, U.S. Secretary of State Anthony Brinken admitted that the United States cannot include Russia on the list of countries supporting terrorism because Russia is not such a country.

Reported that Blinken said at a hearing before the U.S. House Foreign Affairs Committee on the 22nd: Aggression is not a terrorist activity, it is two things.

When asked why the U.S. government did not listen to the calls of the Ukraine authorities and some Westerners and refused to include Russia on the list of countries supporting terrorism, Blinken said: First of all, regarding the designation of a country supporting terrorism, in addition to what Russia does in our view does not fall into such activities, there are also the following considerations: it may undermine certain multilateral cooperation and our coordination based on sanctions (against Russia).

Blinken pointed out: If we come to peace negotiations in the future, it will be extremely difficult to reverse this. You should put this into the game so that you can cross the finish line directly. He added: Another real problem is that it may hinder our proactive efforts to force Russia to pay Ukraine’s huge losses, including using Russian sovereign assets. If (Russia) is identified as a state supporting terrorism, these assets could be frozen during court proceedings.

Blinken said that the executive branch of the U.S. authorities already has sufficient power to take various restrictive measures against Russia and is actively using these powers. They are more precise in describing what Russia is doing. Moreover, we don’t want to encounter unforeseen consequences and derivative effects that may in fact complicate the process of achieving our goals. Blinken concluded.

Reports said that the United States may include countries that it believes have supported international terrorism on its list of countries sponsoring terrorism. The U.S. Treasury Department may take measures against legal persons, natural persons and countries that trade with countries on the list. Iran, North Korea, Cuba and Syria are all on this list.

　　This article provides a detailed overview of the key processes and considerations in electroplating, chemical plating, and hot air leveling for Flexible Printed Circuits (FPC). It highlights the importance of pre-treatment in electroplating for maintaining FPC performance, the challenges in controlling plating thickness, and issues related to post-plating stains. Additionally, the article discusses the application of chemical plating when FPC conductors cannot serve as electrodes and the quality concerns that may arise. Finally, it examines the use of hot air leveling on FPCs, focusing on adhesion strength and moisture resistance. Through this article, readers will gain a deeper understanding of the common challenges in FPC manufacturing and their solutions.It is strictly required by such a standard, rigid flex pcb Only with today’s development scale, can we have the proud momentum to crush our competitors. https://gekunflex.com/

　　FPC Plating Process

　　

　　1. Pre-treatment for FPC Electroplating

　　

　　After the flexible printed circuit (FPC) undergoes the coating process, the exposed copper conductors may be contaminated by adhesives or ink. Additionally, oxidation and discoloration caused by high-temperature processes can occur. To ensure good adhesion of the plating, these contaminants and oxidation layers must be removed, leaving the conductor surface clean.

　　

　　However, some contaminants are strongly bonded to the copper conductor, making it difficult to remove them with weak cleaning agents. Strong alkaline abrasives and brushing are typically used for this treatment. Since the adhesive used in the cover layer is often epoxy-based, which is not resistant to alkaline agents, this can weaken bonding strength. Although not immediately apparent, during the electroplating process, the plating solution may seep into the edges of the cover layer, and in severe cases, cause delamination of the cover layer.

　　

　　At the final soldering stage, solder might seep beneath the cover layer. Therefore, the pre-treatment cleaning process has a significant impact on the basic characteristics of the FPC, making it essential to pay close attention to the processing conditions.

　　

　　2. Thickness of FPC Electroplating

　　

　　The deposition rate of electroplating metal is directly related to the intensity of the electric field, which varies depending on the shape of the circuit and the position of the electrodes. Generally, the thinner the conductor line and the sharper the terminal end, the stronger the electric field, leading to a thicker plating in those areas.

　　

　　In FPC applications, there are often wide differences in the width of conductor lines within the same circuit, resulting in uneven plating thickness. To prevent this, auxiliary cathode patterns are added around the circuit to absorb uneven current distribution across the plating pattern, ensuring uniform plating thickness across all areas.

　　

　　Electrode structure is key here. A compromise approach can be adopted, where stricter standards apply to areas requiring high plating uniformity, such as molten solder (lead-tin) and gold plating for metal wire bonding, while areas requiring plating for general corrosion protection may have more relaxed thickness requirements.

　　

　　FPC manufacturer

　　

　　3. Contamination of FPC Electroplating

　　

　　Immediately after electroplating, the plated surface may appear fine, but stains, dirt, or discoloration can appear over time. Often, these issues are not detected during factory inspections but are discovered during customer acceptance tests. This happens when the plated surface is not adequately rinsed, leaving residual plating solution, which reacts chemically over time, especially on the flexible surface due to its softness and uneven texture.

　　

　　To prevent this, thorough rinsing and drying are essential. A high-temperature thermal aging test can verify whether rinsing was sufficient.

　　

　　FPC Chemical Plating

　　

　　When the conductor to be plated is isolated and cannot serve as an electrode, chemical plating must be used. Chemical plating solutions are highly reactive, and a common example is chemical gold plating. The chemical gold plating solution is an alkaline solution with a very high pH value.

　　

　　When using this process, it is easy for the plating solution to seep beneath the cover layer, especially if the lamination quality control is poor, leading to weak adhesion. Displacement reactions in chemical plating exacerbate this problem, making it difficult to achieve ideal plating conditions.

　　

　　FPC Hot Air Leveling (HASL)

　　

　　Hot air leveling was originally developed for rigid printed circuit boards (PCBs) to coat them with lead-tin. However, this technique has been applied to FPCs due to its simplicity. Hot air leveling involves immersing the board vertically into molten lead-tin and blowing off excess solder with hot air.

　　

　　These conditions are quite harsh for FPCs. Without special measures, FPCs cannot be immersed in molten solder. To address this, FPCs must be clamped between titanium-steel meshes before immersion. Additionally, the surface of the FPC must be cleaned and coated with flux beforehand.

　　

　　Due to the harsh nature of the hot air leveling process, solder may seep beneath the edges of the cover layer, especially if the bonding strength between the cover layer and the copper foil is weak. Since polyimide films are prone to moisture absorption, moisture can evaporate suddenly under the heat, causing blistering or even delamination of the cover layer. Therefore, drying and moisture control must be performed before FPC hot air leveling.

　　Rolex watches, as a representative of high-end watches, are highly respected by watch lovers all over the world for their accuracy and durability. However, even such a high-quality timepiece may encounter the embarrassment of “strike”. When your Rolex watch suddenly stops moving, don’t panic, because in most cases, this doesn’t mean that you need to send it to an expensive official repair point immediately. This article will provide some practical and easy-to-operate maintenance methods to help you solve the problem of Rolex watches not leaving at home.Today, people are interested in 28mm datejust There are also many dependencies, and the expectations for products are getting higher and higher. https://finewatchcare.com/products/fwc-for-rolex-279173-0003-watch-protection-film?_pos=2&_sid=a17d753d8&_ss=r&variant=46834528551199

　　

　　The difference between manual winding and automatic winding

　　

　　First of all, it is very important to know whether Rolex watches are wound manually or automatically. A manually wound watch requires you to rotate the crown to provide power for the movement; The self-winding watch uses the swing of the wrist to automatically charge the movement. Knowing this will help you choose the right way to deal with it.

　　

　　Check the battery charge.

　　

　　For self-winding watches, the lack of battery power is one of the common reasons that cause the watch to stop. Rolex watches are usually powered by lithium batteries. Checking the battery charge is the first step. You can try shaking or shaking the watch gently to activate the automatic winding system in the movement and see if it can be restarted.

　　

　　Manual winding skill

　　

　　For a watch wound manually, the correct manual winding method is equally important. First of all, make sure that the crown is in the correct position (usually there are three positions: neutral, calendar adjustment and winding). Then rotate the crown for manual winding. Rotate clockwise and stop when you feel resistance to avoid damaging the movement.

　　

　　Cleaning and lubrication

　　

　　Dust and dirt accumulated in daily use may also lead to watch failure. Regular cleaning and lubrication of the gear system can effectively prevent such problems. Gently wipe the case and buckle with special cleaner, and wipe the glass surface and metal surface with microfiber cloth. For internal parts, a small amount of professional lubricating oil can be used for lubrication.

　　

　　Check the mechanical structure

　　

　　If none of the above methods can solve the problem, a more professional inspection may be needed. Carefully check whether there is obvious mechanical damage or loose parts. If you find anything unusual, please don’t try to fix it yourself-it may require the help of a professional technician.

　　

　　Professional maintenance suggestion

　　

　　If you still can’t solve the problem after trying the above methods, please contact a professional watch maintenance service for inspection and maintenance. Professional technicians will use sophisticated tools and techniques to diagnose and repair problems.

　　

　　In short, in the face of the situation that Rolex watches don’t work, starting with simple self-diagnosis-checking the battery power, learning the correct manual winding skills, cleaning and lubricating regularly and other steps can often solve most problems. However, if the problem is complicated or cannot be solved by itself, please be sure to seek professional help to avoid causing more losses or damage.

　　

　　Remember, while enjoying high-precision time, proper maintenance is also the key to ensure the long-term operation of your Rolex watch!

According to a report by the TASS news agency on March 18, Russian Presidential Press Secretary Peskov told the media on the 18th that Russia does not agree with the US authorities ‘evaluation of the Russian presidential election and is not prepared to take this evaluation seriously.

Earlier, an official of the White House National Security Council said that the U.S. authorities believed that the Russian presidential election was neither free nor fair.

Reported that Peskov pointed out: We absolutely disagree with this evaluation. In a speech to the media late on the 17th, President Putin said that this evaluation was completely unexpected and foreseeable.

Peskov also said that the United States has been deeply involved in the Ukraine conflict and is in fact a country at war with Russia. Russia certainly does not expect it to make other evaluations. He also said that what Russia needs to reiterate is that we never agree with them, which may not be an opinion we are prepared to take seriously or that is important to us in these days.

Russia’s presidential election was held from March 15 to 17, and some regions of Russia adopted remote electronic voting for the first time. After counting 9943% of the votes, the Russian Central Election Commission announced that current President Vladimir Putin was far ahead in the general election with a vote rate of 8732%.
