How to Reduce Ripple of Switching Power Supply?
Three elements to reduce the ripple of switching power supply
To reduce the ripple of switching power supply, we must work hard in the following three aspects:
Power grounding, signal grounding, and equipments grounding, what is the difference between these three types?
How to creat a GND for Your PCB Layout design? The power earthing is mainly for the path of the power loop current.
How do I choose the right sensor for PCBA ?
The production of smart home products is inseparable from sensors. As the sensing components of smart home, without them, there is no way to trigger smart scenes. For example, functions such as lights on when people come, door and window changes, indoor temperature and humidity self-regulation, and rain closing windowsWhen people design other different products, […]
Why do PCB assembly have so many capacitors?
today we share some knowledge about electronic components.We all know that capacitors are the most used components in circuits.
SMT machines for “round PCBs” circuit boards placement
Hi friends,today I will give you an inventory of some application cases on round PCBs “circular circuit boards ” and the models of Qihe pick and place smt machines they use, most videos came from customer sharing.
Pcb cleaning skill:solder cleaning&desolering
Whether it is production or replacement of PCB assembly, there will be some solder slag left on the circuit board. Pcb cleaning is necessary to clean up the solder slag so that it will not affect the use of the circuit board.If the main reason for the shrinkage of the circuit board resistors is to […]
Skill sharing ! How to judge whether the capacitor is good or bad?
As an indispensable part of our daily electrical products, capacitors are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. Most of the causes of damage to electrical products may be caused by damaged capacitors, so how do we test whether the capacitor is good or bad? Today qihe smt equipment take this opportunity sharing with you some methods of measuring the quality of capacitance!
Some discussion about High Speed PCB Design PART3:View the functions and rules of the network system
Hi guys today QIHE SMT continue sharing you with View the functions and rules of the network system High Speed PCB Design
Professional circuit board manufacturers analyze the causes of PCB layer deviation
With the development of high-level and high-precision PCB boards, the requirements for alignment accuracy between layers are becoming more and more stringent.
Visit to former customer‘s store with TVM925 smt pick and place machine feedback
In the past few days, we had a business trip, visited one of my former customers, and visited the customer’s factory with a TVM925 smt pick and place machine working in his workshop.
