1. how to choose PCB plate? The selection of PCB materials must balance the design requirements with the mass productivity and cost Design requirements include both electrical and institutional parts This material problem is usually more important when designing very high-speed PCBs (greater than GHz). For example, in the [...]

PCB board common surface treatment process and its advantages and disadvantages There are many PCB surface treatment processes, common are hot air leveling, organic solderability protection agent (OSP), full-plate nickel-plated gold, heavy gold, heavy tin, heavy silver, chemical nickel-palladium gold, and hard gold plating. A variety of processes. 1, [...]

Simple Meaning of Nouns The via cover oil, ie the solder ring of the via, is covered with ink. Through-hole windowing: The through-hole (via) solder ring exposed (as exposed as a component pad) on the tin, generally can be used to debug the measurement signal, the disadvantage is likely [...]

In the actual trial process, 90% of the gold plate can use a gold plate instead of the gold plate. The poor weldability of the gold plate is his fatal deficiency, which is also the direct reason that  gave up the gold plate! In the process of use, gold [...]

FPC opening - double sided FPC manufacturing process Except for some materials, the materials used in flexible printed boards are basically roll-shaped. Since not all processes must be processed by the tape process, some processes must be cut into sheets for processing. For example, drilling holes in metalized holes [...]

The transmission rate of high speed PCB design and cabling systems is steadily accelerating, And it also brings about some kind of anti-jamming vulnerability. This is because the higher the frequency of transmitting information, the higher the sensitivity of signals, and the lower and higher the power of [...]

What is the meaning of layers in the PCB? The meaning of layers in the PCB Signal Layers: Signal layers include Top Layer, Bottom Layer, and Mid Layer 1...30. These layers are all layers with electrical connections, that is, the actual copper layers. The middle layer refers to the [...]

1, Autoclave pressure cooker Is a container filled with high temperature saturated water vapor and high pressure? The laminated Laminates can be placed in it for a period of time to force moisture to enter the plate, and the plate removed Placed in a high temperature melting tin [...]

The wiring is an extremely important part of the PCB design and it will directly affect the performance of the PCB board. In the PCB design process, layout engineers all have their own understanding of the layout, but all layout engineers are consistent in how to improve the efficiency [...]

Capacitance is one of the indispensable components in modern electronics. It is as large as a line and as small as an electronic motherboard. Due to the large market demand, there are many manufacturers that can now produce capacitors, suppliers are even more, and there are many things that [...]
