Circuit board processing process
The capacitor lead should not be too long, especially the high-frequency bypass capacitor should not have a lead.
The capacitor lead should not be too long, especially the high-frequency bypass capacitor should not have a lead.
The following are the main points and points for attention in selection of PTC self-restoring fuses of overcurrent devices arranged by Shuokai Electronics.
Low frequency oscillators are used to reduce energy consumption, such as in battery-powered systems, and high frequency oscillators are used to respond to events or to perform heavy calculations by the CPU.
installed on the Printed Circuit Board (PCB) surface or other substrate surface, through reflow welding or immersion welding and other methods to be welded and assembled circuit installation technology.
As we all know, circuit protection is mainly to protect the components of electronic circuits from damage under the circumstances of overvoltage, overcurrent, surge, electromagnetic interference, and so on, and the selection of appropriate circuit protect
It is characterized by surface mounting of components and reflow welding technology. It has become a new generation of assembly technology for electronic products manufacturing.
As the temperature increases, the holding current and trigger current will decrease, so it is important to know the temperature of the environment in which PPTC is applied.
This circuit directly led to the development of ADC and is now almost standard in all ADCs except Delta Σ, becoming one of the classic analog circuits in history. Of course, the circuitry is not easy to understand at first glance.
as well as the corresponding single chip microcomputer and supporting compilation software. Key board is generally selected matrix keyboard, has a wide range of practicability.
In addition, in many cases, due to the reaction and dissolution, in the printed circuit industry, residual film and copper may also form accumulation in the corrosion fluid and blocked in the nozzle of the corrosion machine and acid pump, have to stop pro
When wet, the solder can flow and expand freely on the wire and pad to form adhesive connection.
In addition, this capacitor should be purchased with a relatively large volume, and those with a small volume should also be marked 50V4700uF as far as possible.
