The effect of PCBA design defect on manufacturability
The design defects of PCBA are difficult or even impossible to solve in the production process. The negligence of PCB design quality control will lead to the waste of components, materials and working hours, and even cause heavy losses.
Automatic wiring of PCB
Software vendors and third-party engineers have also tried and failed to achieve acceptable performance improvements.
Multi-person online collaborative PCB design
The load on the server is lighter than that on the client and therefore does not affect system performance. Tests on this environment show that the server is very responsive and does not slow down the client.
How to design pcb window opening
introduces how to realize the PCB wire window on tin, finally describes the PCB design how to set the steps of wire window, follow the small series together to understand.
In PCB design "ground" division and processing method
The specific use of which connection depends on the specific situation. These are the PCB design must understand the content, but also important data. How to partition in PADS is described later in this article.
PCB does not need to use phosphorus containing copper ball _ phosphorus copper ball in PCB application overview
through the titanium electrode rolling plating method to carry out the first and second rolling plating, improve the thickness of the copper layer to enhance the actual effect of the conductivity of the guide hole.
Explain in detail the PCB design of phosphorus copper ball
In this paper, the key is to introduce PCB phosphorus copper ball in detail, the first detailed introduction of PCB electroplating copper need to use phosphorus containing copper ball, followed by the discussion of the use of phosphorus copper ball in PCB
Harm of phosphorus moisture content in Pcb to anodized phosphorus film
the control of hydrochloric acid concentration value need not be slightly lower, the current intensity is slightly higher, not only the amount of the area and hemp sand can be defeated.
How to reduce ESD interference in PCB design process
in the design of PCB board, PCB anti-ESD design can be realized by layering, proper layout and wiring and installation. The PCB layout and wiring can be adjusted to prevent ESD.
The debugging procedure and method of PCBA machining circuit board
PCBA machining circuit board debugging steps and methods: 1. Board surface observation and resistance check, 2. Install components, 3. Detect power supply output voltage, 4. Preset overcurrent protection current, 5. Install and test other modules
Circuit board PCBA processing process is introduced
Circuit board PCBA processing process can be roughly divided into: empty plate loading - printed solder paste - mounting devices - reflow welding -AOI testing - receiving plate - finished product inspection - parts after welding - circuit board open/short
