     After PCB soldering the component, it is called PCBA. PCB has no function, it can only function with the circuit after smt. PCB raw material: copper clad laminate is the base material for manufacturing printed circuit boards. In addition to supporting various components, electrical connection or electrical insulation between them can also be achieved. In short, it is a thin board containing integrated circuits and other electronic components. It will appear in almost every electronic device. If there are electronic components in a certain device, they are all mounted on PCBs of different sizes. In addition to fixing various small parts, the main function of the PCB is to provide electrical connections between the upper parts. What is SMT? SMT is an abbreviation for surface mount technology. SMT is a new generation of electronic assembly technology, and it is also the most popular technology and process in the current electronic assembly industry. It co...

The printed circuit board can be made of various metal materials. These special PCB can be called  metal base PCB . The choice of metal depends on their application. The Aluminum PCB is a  relatively  popular metal substrate with good heat dissipation function and can be applied to many fields in modern times.   What is Aluminum PCB? Aluminum PCB are one of the most commonly used PCB types.  It uses standard FR4 laminate s  and aluminum core s , which  are  effectively cooled by a  hot melt coating  and is widely used in fields involving tight tolerances and high power.  A luminum  PCB  are designed and manufactured differently than other types of PCBs .  It  usually  consists of three main layers. 1.  Base layer: The base layer is made of aluminum alloy substrate. 2.  Circuit layer: The circuit layer of the aluminum PCB is composed of copper foil.  These copper foils can be used in different ...

     Nowadays, various electronic devices are becoming more and more important in our daily lives. All kinds of electronic products need to use circuit boards, so the types of circuit boards are also diverse. Most of these devices will use   flexible PCB , if without it, many electronic devices will not work properly. Different type of PCB have their own advantages. As one of the most common circuit boards, flexible PCB has the following main advantages: 1.  Flexibility Elasticity and bending ability are the main advantages of flexible PCBs, they can be manipulated in various ways to fit the folds and creases of the edges. The flexibility of this circuit board also means that it is more reliable and durable than ordinary PCBs, it can also reduce the impact of vibration, and there are few wiring on the circuit board. Minimal wiring eliminates the needs for interface connections such as solder joints, contact crimping and connectors. 2.  Reduce weight and spa...

     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-i...

     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 ...

       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 a...

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 compa...
