DfRwk cannot be found in the list of DfX Design Guidelines. DfX refers to various design guidelines collected under the heading "Excellent Design". You may have heard of more popular guidelines, such as design for manufacturability (DFM), design for assembly (DFA), or design for test (DFT). But what about design rework (DFRWK)? DFRWK is not [...]
Automatic soldering machine What is the function of the circuit board soldering machine? Friends who have not been exposed to automatic soldering equipment may not understand the influence and function of automatic soldering equipment in the electronics industry. The automatic soldering machine manufacturer Yuli Automation talks about the circuit board soldering machine. The circuit board [...]
China is a global PCB producer, and it accounts for more than half of the global PCB output value. With the rapid development of the IT industry, consumers have higher and higher requirements for electronic products, and the production of PCB boards must also be improved. In order to achieve the quality control of the [...]
The application of circuit boards is very wide, from office equipment: such as calculators, digital cameras, radios; to household equipment: air conditioners, refrigerators, stereos; to industrial equipment: GPS, automobiles, instrumentation, medical equipment... you can say circuits The board is in every corner around us. The identification of the components on the circuit board is one [...]
Triple proof paint is a specially formulated coating used to protect circuit boards and related equipment from environmental erosion. Three anti - paint has good resistance to high and low temperature; After curing, it forms a transparent protective film, which can protect the circuit from damage in the case of chemical substances (e.g. fuel, coolant, [...]
applications This kind of packaging has its own unique characteristics, so in some electronic circuits will be applied, such as MP3 player, electronic organ, digital camera, game console, etc. Some low-cost circuits also use this type of package. In fact, COB soft packaging is not limited to chips, but is also widely used in LED. [...]
Circuit board Circuit board it is more common in our daily life, electronic appliances products have, but its products are different circuit board specifications and sizes are not the same, generally speaking, it is divided according to the number of layers of words into single panel, double panel, multilayer board three categories. Multilayer Pcb Nowadays, [...]
As the PCB surface welding type to lead-free conversion, circuit board welding temperature rise under ultra-high, thermal shock resistance of the surface resistance welding layer demand is higher and higher, to end surface treatment and resistance welding layer (film) ink, cover of peel strength, and the adhesion strength of the base copper demand is higher [...]
In recent years, SMOBC method and graphic electroplating method are two typical processes for the manufacture of double face metallized printed circuit boards. Process traverse method is also used in some specific situations. 1. Graphic plating process flow Foil sheet -- -- -- -- > > cutting benchmark percussive drill hole -- -- > CNC [...]
Printed circuit board (PCB) is a key element of product success. For electronic equipment, PCB is essential - by using circuits and copper wiring to connect different components to each other, PCB gives the equipment a long life. These factors are influenced by physical plate constraints such as size, material, layer and plane, and connectivity. [...]
