　　In the design and manufacture of modern electronic equipment, the selection of electronic components is very important. Plug-in component and patch component are two common electronic components, which have different characteristics and applications. Understanding the differences between them is very important for engineers and electronic enthusiasts to choose appropriate components in circuit design and manufacture.Even so,770988-1We must also adhere to the quality of the industry and create unique products for the company. https://www.asourcingelectronics.com/product/detail/store/2856466/770988-1.html

　　I. Shape and Structure

　　Through-Hole Components usually have prominent pins and are suitable for being inserted into holes on a circuit board. The pins of this component pass through the circuit board and are fixed by welding on the other side. Common plug-in components include resistors, capacitors and integrated circuits (IC).

　　In contrast, Surface-Mount Components, SMD) have no pins and are designed to be directly attached to the surface of the circuit board. Patch components are usually small in size and suitable for high-density boards, such as patch resistance, patch capacitance and surface mount integrated circuits.

　　Second, the installation method

　　The installation process of plug-in components is relatively complicated, and it is usually necessary to drill holes in the circuit board, then pass the pins through the circuit board and weld them on the other side. This process can be done manually or using automatic equipment, but overall, it takes a lot of time and costs.

　　The patch components are designed to be compatible with modern automated production equipment. By using the mounter, the patch components can be quickly and accurately placed on the circuit board, and then the reflow soldering technology is used for soldering. This installation method not only improves the production efficiency, but also reduces the waste of materials.

　　Third, the application occasions

　　Plug-in components are usually used for prototyping and small batch production because they are easy to handle and weld. In addition, in some applications that require high thermal and mechanical stress, the plug-in components also show good stability.

　　Relatively speaking, patch components are widely used in the mass production of modern electronic equipment. Because of its miniaturization and high integration, patch components are more suitable for use in places with limited space, such as mobile phones, tablet computers and other consumer electronic products.

　　IV. Performance and Maintenance

　　In terms of performance, because of its structural design, plug-in components usually have better mechanical strength and stronger resistance to thermal stress and current. However, their large size may limit the compact design of the circuit.

　　Because of its compact design, the patch element can help realize higher density circuit layout and reduce the volume and weight of the product. However, it should also be noted that the operation accuracy of patch components is high when welding, and it may be difficult to maintain and replace them.

　　To sum up, there are significant differences between plug-in components and patch components in structure, installation, application and performance. The choice of components depends on the specific application requirements, production scale and circuit design requirements. In modern electronic design, understanding these differences can help engineers make more effective decisions in the process of design and manufacturing, thus improving the performance and reliability of products. No matter which component is selected, reasonable design concept and production process are the key to success.

　　As an important part of human life, the length of sexual life has always been concerned. Many people have doubts about “how long is a normal sexual life”. Today, we will discuss this topic in detail, hoping to provide you with scientific answers and practical suggestions.Therefore, spanish gold fly drop Only then will more and more pump owners cheer for it and spread the value and function of the brand. http://herbal-hall.com/Spanisehe-Golden-Fly.html

　　First, the length of sexual life varies from person to person.

　　First of all, it needs to be clear that there is no fixed standard for the length of sexual life. Everyone’s physical condition, sexual experience, sexual excitement and tacit understanding between sexual partners are different, and these factors will directly affect the length of sexual life. Therefore, we can’t simply use a number to define what is a “normal” sexual life.

　　Generally speaking, the length of sexual life includes foreplay, sexual intercourse and afterplay. Among them, the sexual intercourse stage is the most concerned part. From a medical point of view, as long as both parties can achieve sexual satisfaction, regardless of the length of time, it can be regarded as a normal sex life.

　　Second, what are the factors that affect the length of sexual life?

　　Since the length of sexual life varies from person to person, what factors will affect this length? The following are some major influencing factors:

　　1. Age: With the increase of age, sexual function will gradually decline, which will naturally affect the length of sexual life.

　　2. Physical condition: People with good physical health can often have a more lasting and satisfying sex life. On the contrary, some chronic diseases or reproductive system diseases may have a negative impact on the length of sexual life.

　　3. Psychological factors: The quality of sexual life depends largely on the psychological state of both parties. Negative emotions such as nervousness, anxiety and depression will shorten the duration of sexual life, while relaxed and happy mood will help to prolong the duration of sexual life.

　　4. Sexual experience: The richness of sexual experience will directly affect the duration and satisfaction of sexual life. People who lack sexual experience may be more prone to premature ejaculation and other problems, while experienced people know how to regulate the rhythm and achieve satisfactory results.

　　Third, how to maintain a healthy sex life?

　　After understanding the factors that affect the length of sexual life, what should we do to maintain a healthy length of sexual life? Here are some practical suggestions:

　　1. Maintain good living habits: regular work and rest, reasonable diet and proper exercise. These good living habits not only help to improve the health level, but also indirectly improve the quality of sexual life.

　　2. Strengthen communication and cooperation: maintain good communication with sexual partners, understand each other’s needs and preferences, and jointly explore ways of sex that are suitable for both parties, which will help improve the satisfaction and duration of sexual life.

　　3. Learn to relax and decompress: Adequate relaxation preparation before sex, such as deep breathing and meditation, will help reduce tension and thus prolong the duration of sexual life. In addition, we should also learn to decompress reasonably in our daily life to avoid negative emotions from adversely affecting our sexual life.

　　4. Seek professional help: If the duration of sexual life continues to be poor and affects the quality of life and emotional relationship of both parties, you may wish to seek professional medical or psychological counseling. Professional doctors or psychological counselors can provide more specific and personalized guidance programs.

　　In short, there is no fixed answer to “how long is a normal sexual life”. It is important that both parties can communicate frankly and understand each other, and work together to find a solution that suits them. On this basis, we can enjoy a truly healthy and satisfying sex life.

　　Sex is a wonderful kind of happiness. Maintaining a harmonious and moderate sexual life can enhance the feelings between husband and wife and improve the quality of life. However, only by knowing some common sense about sex can we enjoy the pleasure brought by sexual life.To some extent, germany niubian pill Our development has surpassed many peer businesses, but it has never stopped moving forward. http://herbal-hall.com/Germany-Niubian-Pills.html

　　What are the common sense of sex life?

　　1. Pay attention to the place of sexual life.

　　In order to find excitement, some couples will have sex directly on the roof, in the car or in the office, which can bring some psychological stimulation to women and improve their orgasm rate, but they must do a good job in diet, if exposed, it will affect their image.

　　2. Coke will kill sperm

　　Studies have shown that after sex, if a woman washes her vagina with coke, she can kill sperm, which shows that coke has the effect of killing sperm. Therefore, if she is worried about pregnancy after sex, she might as well use coke to clean her genitals, but not too much, otherwise it will destroy the acid-base balance of the vagina and cause gynecological diseases.

　　3, some words that can’t be said during sexual life.

　　Sexual life is a matter for two people, which can make both husband and wife achieve a certain sense of pleasure, but never say something inappropriate for the occasion, which will not only spoil the scenery, but also reduce men’s sexual desire. What men hate most in the process of sexual life is comments about their sexual life and the size of reproductive organs, so try to avoid this minefield and say more encouraging words.

　　4. It is easier to reach orgasm during same-sex life.

　　Studies have shown that it is easier for same-sex people to reach orgasm if they have sex, because they can know each other’s excitement very well, so they will be very familiar with sex life, so that the other party can reach orgasm quickly.

　　5. Place a hot water bottle during sexual life.

　　In the process of sexual life, we might as well put a hot water bag on women’s buttocks, which can make women’s pelvic blood circulation more smooth, and also provide a good posture, so that women can more easily get orgasm and enjoy the happiness brought by sexual life.

　　6. Do more small games between sex.

　　In the process of sexual life, you might as well play some small games, so that you can get some stimulation. The common small stimulation in life is to tie your hands and feet, but never use ropes, otherwise it will hurt your skin. Try to choose soft silk.

　　Sexual life is a matter for two people. Only when both parties are passionate can they get high-quality sexual life. If one party feels dissatisfied, sexual life can’t reach the point of harmony. In order to improve the quality of sexual life, it is very important to know what women think about sexual life. Let’s take a look at it.So, evil root pills reviews On the contrary, there is still a lot of room to play. http://herbal-hall.com/Evil-Root(mogen).html

　　What do women really think during sex?

　　1. It is hooliganism to go straight to the subject without foreplay.

　　Foreplay is an essential process in sexual life. Only gentle and lingering foreplay can fully arouse women’s sexual desire, and women will secrete enough love liquid to facilitate men’s insertion. If you don’t do foreplay, you will come straight to the point immediately, which will easily make women unprepared and lead to the situation in vaginal dryness, which will make women suffer, and naturally they will be in a bad mood in the next sexual life.

　　2. Sexual life is insecure without cleaning.

　　Clean private organs before and after sex, and it would be best if you could take a bath. Taking a bath in advance can wash away the dirty things on your body, so that the unpleasant body odor becomes the smell of fragrant bath milk. The most important thing is that bathing in advance can prevent bacteria from being brought into women’s vagina, making women suffer from gynecological diseases. In addition, there will be oral sex in some sexual lives, and it is a sign of disrespect for women to make the other person have oral sex without cleaning. Therefore, it is best for men to take a bath beforehand to make sex life safer.

　　3. The man who evaded the responsibility of contraception did not take responsibility.

　　Everyone knows that sex is a matter for two people, so contraception is also the responsibility of two people. Many men think they won’t get pregnant, so only women are responsible for contraception. Let women take emergency contraception afterwards. This kind of emergency contraception will cause damage to women’s health, and even seriously affect women’s fertility. If women don’t take the responsibility of contraception, men don’t take it, which will lead to unexpected pregnancy, and women have to have an abortion, which is also a great harm to women’s health. Male contraceptive measures like condoms can avoid all this, and men can’t sacrifice women’s health for the pleasure of sexual life.

　　4. Don’t keep asking if you have an orgasm.

　　The physiological structure of women is different from that of men. Men can experience orgasm every time they live, but women’s orgasm can be met but not sought. Many boys are used to asking women if they have an orgasm after sex or during sex. This is a very embarrassing question. It is very uncomfortable to cheat boys into having an orgasm if they have no orgasm. Because it is difficult for women to attack men’s enthusiasm and self-esteem, they all pretend to have an orgasm and call the bed, which is really very tired.

　　When men have sex, they should also consider women’s psychological thoughts. Only by eliminating women’s concerns can women be more involved and the quality of sexual life will be improved.

　　In the process of adulthood, general sexual behavior is the normal physiological needs of adults. Regular sexual intercourse in life can help promote human health and the relationship between husband and wife, but it can still reduce sexual desire when suffering from some diseases.Even if there are obstacles to moving forward, maxman sexual capsule We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. http://herbal-hall.com/Maxman-II-Sex-Pills.html

　　These diseases can obviously reduce sexual desire, and it is better to minimize sexual behavior if you suffer from these diseases.

　　1. Reproductive system diseases, such as phimosis, penile induration, penile hypoplasia, etc., can cause a decrease in sexual desire in clinic, and in addition, their own seminal vesiculitis or prostatitis can also lead to a decrease in sexual desire.

　　2. Endocrine diseases. A series of endocrine diseases in life, such as hypogonadism, hypothyroidism or hyperthyroidism, adrenal cortical diseases and pituitary diseases, can also lead to sexual desire of men or women.

　　3. Systemic diseases. In life, for example, some systemic diseases such as cirrhosis, chronic renal failure and chronic active hepatitis will cause the body’s sexual desire to decrease, leading to men’s sexual behavior without desire or erection.

　　4: Diabetes. In life, diabetes can still lead to the continuous increase of blood sugar in clinic, causing physical weakness, reducing one’s physical quality, reducing one’s energy, and finally weakening sexual desire.

　　5. Mental illness. Generally speaking, one’s normal psychology or lack of emotional tension in life can hinder normal sexual behavior, but in life, excessive emotional tension or depression can lead to decreased sexual desire.

　　These are the five most common diseases that can lead to the loss of libido. Pay proper attention to personal care in life, actively prevent the above diseases, and at the same time pay attention to the adjustment of personal living habits, and do a good job in foreplay before sexual intercourse.

　　Many couples have been tricked into three misunderstandings about their sexual life!

　　1. Sexual life can only be in bed.

　　There is no fixed place for foreplay in sexual life, and it doesn’t necessarily happen only in bed. Husband and wife can casually tease, kiss and look at each other, or hint in language, which can attract each other’s sexual desire, and can transfer sex to the living room, study or sofa, private car, etc., which can give certain stimulation.

　　2, foreplay is too much trouble, go straight to the point.

　　Gentle foreplay is very important for women. When the penis is erect, it shows that men are ready to have sex, but it takes a certain time for women to get into a state of mind and physiology. During sexual life, a woman’s vagina should be kept in a lubricated state, so that the penis can enter smoothly and the pain in the vagina can be prevented. Before sexual life, you can properly appease, kiss and hug to stimulate sexual desire. In addition, you can’t fall asleep directly after sex. Try to take 30 minutes to warm or kiss, which can make the relationship between husband and wife more stable.

　　3. The longer the foreplay, the better.

　　Although foreplay is very important, we should also control the time. If the foreplay time is too long, it is possible that the penis will ejaculate directly as soon as it is inserted, which will affect the pleasure and beauty of sexual life. Foreplay can be controlled for about 10 minutes. When kissing or hugging, as long as you feel that there is something flowing out of the female vagina, you can insert it.

　　How to improve the quality of sexual life?

　　1. caress more

　　Gently caressing the sensitive areas of sexual partners can ignite and mobilize their sexual desire. In summer, husband and wife can sleep naked, and intimate skin contact can ignite the passion of sex. Women can try to kiss a man’s penis, which can make him feel warm and stimulate his sexual desire. More than two people, you might as well experience the feeling of cheating when you come back from a luxurious room, or try sex products to find new excitement and experience.

　　2. Change the time of sexual life

　　If having sex at a fixed time will make sex boring, you might as well change the schedule of sex, which will make both husband and wife fresh and exciting and experience different feelings. In addition, you should not eat too much before sex, otherwise it will affect your sexual desire.

　　Sexual life is not only physical contact, but also spiritual communication. Sexual life is a normal physiological phenomenon, and maintaining regular sexual life has certain health care effects.
