The Difference between SMT Components and Plug-in Components in SMT Processing

图片
     In SMT processing, SMT components and plug-in components are commonly used components.   Each has its own advantages and disadvantages. Do you know the difference between them?       1.  Both  SMD components and plug-in components are power-type devices, which require high heat dissipation. The performance of plug-in components is higher than that of SM T  components, which can keep the product's performance stable and lasting.     2. The failure rate of the plug-in components is low, which is conducive to inspection, can intuitively feedback out of the defects, and does not need to use special equipment and instruments.     3. The plug-in component has strong anti-vibration ability, and it can maintain the stability of the products better than the SMT component in the face of high-frequency, high-amplitude vibration and bump.     4. The volume of the SMT component is only 1/10 of the traditional plug-in component. Generally, after SMT processing, the volume of electronic prod

What are the Advantages and Disadvantages of the OSP Technology

     With the continuous development of the electronics industry, there are more and more PCB surface treatment technologies, and each technology has its own merits. OSP is a commonly used surface treatment technology process, what are its advantages and disadvantages?       Compared with other surface treatment technologies, OSP is somewhat different.  It uses a chemical method to produce an organic film on the clean bare copper surface, which acts as a barrier between the copper and the air.   OSP is organic, not  metallic,   and its cost is lower than most surface treatment technologies.     Advantages: With this organic film, it can resist the attack of moisture in the air without being oxidized before welding,  can withstand the test of high temperature, maintain good activity, and has a good tinning ability.  This layer of organic film will not cause damage to the sheet material. It can be easily removed by the solder resist during soldering. It can solder the copper wire and the

Three Types of PCB Inks

       In the process of PCB production, ink is indispensable. Ink can be divided into three types. Do you know which three types are?       1.  Circuit Ink The substrate of the PCB board is a copper clad laminate .   There is a layer of copper foil on it, and the circuit ink needs to be exposed, developed and cured by silkscreen printing.   After the circuit is etched, the ink will be removed with an aqueous sodium hydroxide solution.   In addition, the circuit ink will protect the circuit during etching.     2.  Solder Mask Ink There is a layer of green paint on the common PCB, which is actually solder mask ink. According to the curing method, solder mask inks include photosensitive and developing inks,  heat-cured thermosetting inks and UV light-cured UV inks.  According to the  base material  classification, there are  rigid   PCB  solder mask ink, FPC solder mask ink, and aluminum  PCB  solder mask ink. Aluminum  PCB  ink can also be used on ceramic boards.  The main function of t

How to Choose A PCB Manufacturer

Many PCB buyers use the Internet to find  PCB manufacturers .   But there is so much information on the Internet, how  should   we choose a PCB manufacturer?   1.  Technological capability When  PCB buyer  choosing PCB manufacturer,   they   should try  their   best to choose PCB manufacturer   with a  wide range  of  technolog i es  and rich  technical   capabilities, so as not to involve the  technology   beyond the manufacturer's range of capabilities, thereby affecting the delivery time.   HoYoGo can supply with prototype, medium-small-mass volume, rigid, FPC, R-F, HDI, copper base, steel base, Alu, Glass base and all special PCB .       2. Manufacturing Equipment There are many types of PCB, and the requirements for production are quite different, and the equipment used is also different. Generally, when selecting PCB manufacturers, samples will be compared first, and then mass production will be considered. HoYoGo has 2 factory production bases with a monthly production capac

The Role of Soldering Flux in SMT Processing

In the process of SMT  welding  processing,  soldering  flux is often used, so what is the effect of using  soldering  flux?       1. Remove oxide The Abietic  A cid in the  soldering  flux can  have a reduction  react ion   with the oxide film on the surface of the welded metal to generate  C opper  Abietate , which can remove oxides or other  dirt   on the soldering surface.     2. Prevent secondary oxidation During  SMT  welding processing , the  soldering  flux will cover the surface of the welded metal and solder , which can  isolate it from the air and prevent  the  secondary oxidation of the solder.     3. Reduce solder tension When the  soldering  flux removes the oxide on the soldering surface, a certain chemical reaction occurs, which can reduce the surface tension and viscosity of the solder, while increasing the surface activity, thereby improving the wettability of the solder.     4.  Better heat transfer The soldering flux reduces the surface tension and viscosity of the

What are the Advantages of High Frequency PCB?

High frequency PCB   has been widely used in the communication industry, network technology, and high-speed information processing systems, and meets the operating requirements of many high-precision parameter instruments. Do you know why?       1.  High   frequency PCB with small dielectric constant, l oss is also very small. A dvanced induction heating technology can achieve the target heating demand, and the efficiency is very high.     2.  The s maller the dielectric constant, the faster the transmission speed. The high-frequency PCB is made of special materials, which not only  ensure s the   characteristic s of   small dielectric constant, but also maintains the stability during operation.     3. High frequency PCB can not only realize heating of different depth components, but also focus on local heating.  Whether it is surface, deep, or concentrated and dispersed heating methods, it can be easily completed.     4.  Dielectric constant and medium have certain requirements on the

What are the Requirements for PCB Soldering?

      Soldering is an important process in the PCB processing, which plays a decisive role tin the quality of the PCB. So, what are the requirements for PCB soldering?       1. Good solderability Under certain  solder ing conditions, the ability to easily obtain good welded joints is called  solder ability.   In order to improve the solderability, measures such as tin plating and silver plating on the surface can be used to prevent oxidation of the material surface.     2. The surface of the solde ring lug  is clea n In order to achieve a good combination of  solder ing tin and weldment, even if the solderability is good, the surface of the soldering lug must be clean. Due to the long-term storage and pollution, the surface of the soldering lug may produce harmful oxide film, oil stains, etc. So, please be sure to clean the surface of the soldering lug before soldering, otherwise the soldering quality cannot be guaranteed.     3. Suitable flux The function of the flux is to remove the
