Multi-layer PCB stack structure1.1 Selection and stacking principles of the number of layersDetermining the stacked structure of a multilayer PCB requires consideration of many factors. From the perspective of wiring, the more layers, the better the wirin
Reverse technology development of reverse push principle diagram of PCB copy boardIn the research of PCB reverse technology, the reverse deduction schematic diagram refers to the deduction of the PCB circuit diagram based on the PCB file diagram or the di
PCB high current carrying methodthree aspects:1. PCB carrying large current operation method2. Precautions for PCB carrying high current3. Recommended operation for PCB carrying large current1. PCB carrying large current operation methodLet me talk about
PCB operational amplifier circuit design skillsPrinted circuit board (PCB) layout plays a critical role in high-speed circuits, but it is often one of the last steps in the circuit design process. There are many aspects of high-speed PCB routing, and a gr
How to do PCB reverse developmentIn the research of PCB reverse technology, reverse derivation schematic diagram refers to deriving the PCB circuit diagram based on the PCB file diagram or directly drawing the PCB circuit diagram according to the actual p
The coating thickness on the hole wall of the element is not enough, resulting in poor tin plating in the hole. Generally, the thickness of the pore wall should be above 18 microns. 4. The hole wall is too rough, resulting in poor tinning or pseudo-weldin
Analysis of PCBA parts packaging technologyPlug-in packaging technology surface adhesive packaging technology
There is green oil in the element hole, resulting in poor tin plating in the hole. The green oil in the hole should be kept below 10 percent of the hole wall and the number of holes in the internal green oil should be below 5 percent.The life of wood and
Basic knowledge of printed circuit board PCB1. Printed circuit board (PCB)PCB is the abbreviation of Printed Circuit Board (Printed Circuit Board). Also known as printed circuit board, printed circuit board, because it is made by electronic printing, it i
Aluminum substrate PCB circuit board Introduce the advantages and disadvantages of ceramic PCB circuit boards. One of the disadvantages is that the ceramic substrate is too expensive and fragile. Ordinary glass fiber PCBs have poor heat dissipation, ce
The role of metal core PCB in the Led industryIn today's technological age, the demand for lamps and lighting systems is on the rise. In addition, there are many LED products that are becoming more and more common in the lighting industry. In the past ten
High current thick copper board PCB designThick copper PCB is a circuit board with copper thickness ≥3oz/sq. Ft on its exterior and interior. What makes a board classified as a thick copper PCB is its thicker plating. When producing thick copper PCBs, the
