Grundläggande regler för layout och kabeldragning av komponenter

Det finns några grundläggande regler som bör följas när man utformar en layout. Dessa inkluderar att hålla ström- och jordplanen inom kortet, undvika korsnätning och placera de mest kritiska komponenterna först. Du bör också försöka placera ICs och stora processorer inuti kortet. Om du följer dessa regler bör du inte ha några problem med att designa och skapa ett kretskort.

Avoid crossing nets

When wiring components together, you must avoid crossing nets. If there are vias, make sure they are far enough apart to avoid cross-netting. Another way to avoid crossing nets is to place one IC’s positive pin ahead of the other IC’s negative pin. This way, you’ll avoid crossing nets on the PCB.

Place large processors and ICs inside your board

Microprocessors, ICs, and other large electronic components are the heart of most circuits. They are ubiquitous and can be found on nearly every circuit board. They can be simple devices with just a few transistors or complex devices with millions or even billions of transistors. There are many types of ICs available, including 8-bit microcontrollers, 64-bit microprocessors, and advanced packages.

Avoid placing vias on power and ground planes

Placing vias on power and ground planes creates voids, which can create hot spots in the circuit. For this reason, it is best to keep signal lines away from these planes. A general rule of thumb is to place vias 15 mils apart. In addition, when placing signal lines, ensure there are 1350 bends per via.

In a typical PCB power distribution system, power and ground planes are located on the outer layers. These layers are characterized by their low inductance and high capacitance. In high-speed digital systems, switching noise can result. To mitigate this, use thermal relief pads to make electrical connections.

Avoid placing vias on traces

When wiring components, it is important to avoid placing vias on traces. Vias are holes drilled in the board through which thin copper wires pass and are soldered on both sides. Ideally, vias should be placed at least one-eighth wavelength away from the traces. This practice will decrease the operating temperature of the IC and make the design more reliable.

Vias are very useful in moving signals from one layer to another. Unlike traces that run from layer to layer, they are also easy to identify if any design changes are needed. Vias are the jack-of-all-trades of a PCB layout, providing electrical connectivity between layers. Additionally, they serve as an effective tool in transferring heat from one side of the board to the other.

Varför aktiva komponenter är dyrare än passiva komponenter

Elektronik är en central del av vår moderna värld och används i nästan alla branscher. För att de ska fungera korrekt är de beroende av en mängd olika komponenter. Aktiva komponenter är dock dyrare än passiva. Den här artikeln förklarar skillnaden mellan de två typerna av elektronikkomponenter. Du får veta varför aktiva komponenter är dyrare och varför passiva är billigare.

Transistorer

Det finns två grundläggande typer av elektroniska komponenter: aktiva och passiva. Aktiva komponenter används för att producera ström, medan passiva komponenter används för att lagra den. Båda typerna är viktiga i elektroniska apparater, eftersom de säkerställer att den elektroniska utrustningen fungerar som förväntat. Det finns dock några viktiga skillnader mellan aktiva och passiva elektroniska komponenter.

En transistor är en aktiv komponent, och det är en halvledaranordning som kräver extern ström för att fungera. Transistorn kan öka eller minska den ström som flödar i en krets. En transistor kan också ändra riktningen i vilken elektriciteten flödar.

Induktorer

Aktiva komponenter är sådana som producerar ström eller spänning, medan passiva komponenter inte gör det. Skillnaden mellan aktiva och passiva komponenter ligger inte bara i deras fysiska utseende, utan även i deras funktion. En aktiv komponent har till uppgift att förstärka effekten, medan en passiv komponent inte har något syfte.

Aktiva komponenter kräver i princip en extern energikälla för att fungera. Passiva komponenter genererar ingen energi, men de lagrar energi och styr strömflödet. Ett exempel på en aktiv komponent är en transistor, medan en passiv komponent är ett motstånd.

Induktorer filtrerar bort högfrekventa signaler

En induktor kan användas i en elektrisk krets för att filtrera bort högfrekventa signaler. Den fungerar genom att minska signalens frekvens till en frekvens som är lägre än ingångsfrekvensen. I allmänhet letar ingenjörer efter ett förhållande som går ner till 1/(2*x)1/2. De vill också veta hörnfrekvensen, som kan bestämmas grafiskt. X-axeln visar frekvensen, medan Y-axeln visar förstärkningen.

Ett sätt att bestämma induktorns induktans är att mäta spänningen över induktorn. Detta hjälper dig att bestämma induktorns känslighet för en högfrekvent signal. Induktansen kan också mätas med hjälp av hörnfrekvensen. Tänk på att induktansen inte är en exakt mätning, eftersom kretsen alltid är utsatt för förluster.

Transistorer är förstärkare och omkopplare

Transistorer är elektriska enheter som används för att styra signaler. De består av två grundläggande komponenter: en emitter och en kollektor. Emitterdelen av en transistor är framåtspänd och kollektordelen är bakåtspänd. När en transistor arbetar i sitt aktiva område kommer kollektorsidan att visa en svagt böjd kurva. Kollektorområdet är den viktigaste delen av en transistor eftersom det är där kollektorströmmen är mest stabil.

Transistorer kan klassificeras som halvledare av antingen p-typ eller n-typ. När de används som brytare fungerar de på samma sätt som förstärkare. De kan fungera som omkopplare genom att ändra den ström som passerar genom basen.

Induktorer är icke-reciproka

Induktorer är icke-reciproka om två eller flera av dem är parallellkopplade och det inte finns någon ömsesidig induktans mellan dem. Detta innebär att summan av deras totala induktanser blir mindre än summan av deras individuella induktanser. Detta är fallet för parallella induktorer, där spolarna är anordnade i motsatta riktningar.

Ömsesidig induktans är ett annat sätt att definiera reciprocitet. En ekvivalent krets är en krets där den primära och sekundära delen har samma ömsesidiga induktans. I en reciprok transformator förlorar den andra delen ingen energi under den magnetiska kopplingen, så den representerar inte klumpad energi.

Induktorer kräver ingen extern energikälla

Induktorer lagrar energi genom att ändra magnetfältets styrka beroende på hur mycket ström som flödar genom dem. Ju starkare ström, desto starkare magnetfält och desto mer energi lagras. Denna egenskap är unik för induktorer jämfört med resistorer, som i allmänhet avger energi i form av värme. Dessutom beror mängden energi som lagras i en induktor på mängden ström som flödar genom den.

Huvudsyftet med en induktor är att lagra energi. När elektrisk ström passerar genom en induktor induceras ett magnetfält i ledaren. Dessutom motverkar det inducerade magnetfältet förändringen av ström eller spänning. Resultatet blir att en jämn likström passerar genom en induktor, som symboliseras av bokstaven L. Denna egenskap gör induktorer användbara i stora kraftapplikationer där de inte kan ersättas med en konventionell elektrisk komponent.

De 3 främsta orsakerna och motåtgärderna till brister i lödpasta vid PCB-design

There are several causes and countermeasures for solder paste deficiency in a PCB design. These include cold solder joints, inaccurate placement, too much heat during soldering, and chemical leakage. Here are some of the most common causes and how to resolve them.

Cold solder joints

In order to avoid the formation of cold solder joints, PCB designers must design the PCB in such a way that all of the components are placed in similar orientations and have good component footprints. This helps to avoid problems with thermal imbalances and asymmetry in solder joints. Also, it is important to design PCBs in such a way that each component is positioned on a D-shaped pad. It is also important to avoid the use of tall components since they create cold zones in the PCB design. Moreover, components near the edge of the board are more likely to get hotter than those in the center.

A faulty solder joint can be a result of a variety of factors, including the lack of flux or a poorly bonded joint. A clean work area is essential for good solder joint quality. It is also important to re-tin the soldering tip to prevent oxidation.

Kemiskt läckage

If you are a designer of PCBs, you may be interested in learning how to avoid chemical leakage. This problem is caused by solder balls, which appear as small spheres of solder that adhere to the surface of a PCB’s laminate, resist, or conductor. Due to the heat generated, the moisture near the through holes in a PCB can turn to steam and extrude the solder.

Solder bridging is another problem caused by a deficiency of solder paste. When solder cannot separate from a lead before solidifying, it forms a short circuit. While the shorts are often invisible, they can wreak havoc on a component. Several factors can cause this problem, including the number of pins on a PCB, the distance between them, and the reflow oven’s setting. In some cases, a change in materials can also cause solder bridging.

Too much heat during soldering

Solder paste can be prone to deformities when it reaches a certain temperature during soldering. Too much heat during soldering can result in solder balling and discrete deformities. Too much solder paste can also lead to too much flux outgassing. These factors can contribute to solder balling and deformities in PCB design.

Solder paste should never interact with moisture or humidity. The solder mask must be correctly positioned and the stencil bottom should be cleaned regularly. Another common PCB design error is known as the tombstone effect, or “Manhattan effect,” caused by force imbalances during soldering. The effect resembles the shape of a tombstone in a cemetery. However, it represents a defunct PCB design with an open circuit.

Cleaning the material properly after drilling

Solder paste deficiency is the result of a material being improperly cleaned after drilling. Solder wire should be at the correct temperature and ideally be completely wetted with the pads and pins. If the solder is not adequately wetted, it may lead to the formation of a solder bridge or other defects. The right amount of solder is necessary to wet the pads and pins evenly. If it is not, it can form a metal oxide layer on the bonded object. This can be fixed by cleaning the material well and by using the right soldering iron.

Insufficient solder can cause several problems with the circuit board. Inadequate solder can cause a sand hole, broken line, “blow hole” or “solder joint void.” Insufficient solder paste can also lead to the removal of tin from components. It’s essential to avoid such problems by following the PCB design process.

Preventive measures

Solder bridging occurs when solder gets into a space it shouldn’t. Solder bridging can be prevented by using larger component leads. When pads are too small, the solder has to wet a larger area and flow a smaller volume up the lead. This results in solder balls that form and cause shorts. It is important to place pads at optimal positions and use proper solder paste in the soldering process.

A lack of solder paste on the board can also cause component leads to be warmer than pads because component leads have less thermal mass and a higher flow of air around them. Increasing the soak time of solder paste will prevent this issue and equalize temperatures across the assembly. It also reduces the tendency for solder to flow towards warmer surfaces. Another prevention method is to optimize the stencil design to minimize the amount of solder paste on trouble areas. In addition to using a stencil, ensuring that the components are not damaged before placement can help reduce solder paste in problematic areas. Copper balancing can also be used to even out the heating and cooling of the PCB.
