Look at the PCB to see if there is scratch where the patch element falls off. Scratch where the PCB patch element falls off will also make the adhesion of the green oil insufficient, which can cause the patch element to fall after the PCB has passed the t
Integrated circuit board environmental protection ROHS testingThe integrated circuit board ROHS detection circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization
Finished product testing of integrated circuit chips1. Chip introduction74HC138 is a three-channel input, eight-channel output decoder. The 74HC138 decoder accepts 3-bit binary code inputs (A0, A1 and A2). 74HC138 has 3 enable terminals: Eˉ1 and Eˉ2 are a
Characteristics and types of hybrid integrated circuitsA hybrid integrated circuit is an integrated circuit made by combining a semiconductor integration process with a thin (thick) film process. Hybrid integrated circuits are made by forming thick or thi
Generally speaking, integrated circuit board is the integrated circuit board, which is widely used in the fields of computer, TV, air conditioning and other electronic products to be automatically controlled.
Not only in the PCB board copy process, is in the circuit maintenance, often need to remove the integrated circuit from the printed circuit board, and because the IC pins are more and more dense, it is difficult to disassemble, sometimes will damage the i
Under normal circumstances, for the circuit below the microwave frequency band (including low frequency and low frequency digital circuit), careful planning under the premise of a comprehensive grasp of various PCB design principles is the guarantee of on
Keyou Circuit is a dedicated to PCB rapid proofing and mass production, with high precision single side/double side/multilayer circuit board .
In the process of PCB board copying, since the circuit board needs to be split, the integrated circuit and other components are removed to make BOM list, and the bare PCB board is scanned and copied.
It is characterized by simple production process, low cost, short cycle, good wear resistance, electrical conductivity, can make the single panel to achieve high density, miniaturization, lightweight, suitable for TV, telephone, video recorder and electro
Integrated circuit board is the use of semiconductor production process, in a small monocrystalline silicon wafer production of many transistors and resistors, capacitors and other components, and in accordance with the multi-layer wiring or tunnel wiring
Then use the same method to separate the other pins of the integrated circuit from the circuit board, and finally you can remove the entire integrated circuit.
