It costs some money to test a friendly PCB design, however, it costs more to test a difficult PCB design. Testing itself has a cost, and the cost of testing increases with the increase of the number of tests; From online testing to functional testing and
The size of these two parts determines the size of the hole. Obviously, in the design of high speed, high density PCB, the designer always wants the hole as small as possible, the template can leave more wiring space, in addition, the hole is smaller, its
From the two formulas discussed above, it can be concluded that the use of thinner PCB board is beneficial to reduce the two parasitic parameters through the hole.
The rapid development of RF integrated circuits for wireless digital audio and video data transmission systems, wireless remote control, telemetry systems, wireless data acquisition systems, wireless networks and wireless security systems to solve the bot
They can be integrated on a small circuit board, used in wireless digital audio, digital video data transmission system, wireless remote control and telemetry system, wireless data acquisition system, wireless network and wireless security system and many
Complete pre-test documentation includes parts lists, PCB design data (mainly CAD data) and detailed information about the functions of the service components (such as data sheets).
To solve these problems, measures can be taken in circuit layout, new testing methods can be adopted, and innovative adapter solutions can be adopted. The solution of the second problem also involves making the test system used as a separate process take
PCB board classification is many, common paper based printed circuit board, epoxy glass fiber cloth printed circuit board rice composite substrate printed circuit board, special substrate printed circuit board metal substrate.
This paper first introduces what is impedance and impedance type, then introduces the PCB circuit board why to do impedance, describes the significance of impedance for PCB circuit board, the specific follow Xiaobian together to understand.
Electrolysis of copper foil is also used in situations where the carrying capacity of the current can be increased by increasing the weight of copper to achieve a copper width, such as planar inductors.
pcb design should begin with an understanding of the manufacturer's capabilities. When designing manufacturable PCBS, IC companies are usually contacted regularly regarding functionality and cost reduction techniques.
Virtually every electronic product consists of one or more printed circuit boards (PCBS). PCBS immobilize IC and other components and interconnect them. A large number of PCBS were created for portable electronic devices, computers and entertainment devic
