Basic Rules of Layout and Components Wiring

Basic Rules of Layout and Components Wiring

There are some basic rules that should be followed when designing a layout. These include keeping the power and ground planes within the board, avoiding cross-netting, and placing the most critical components first. You should also try to place ICs and large processors inside the board. By following these rules, you should have no trouble designing and creating a circuit board.

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.

Por qué los componentes activos son más caros que los pasivos

Por qué los componentes activos son más caros que los pasivos

Electronics are a central part of our modern world and are used in almost every industry. These devices depend on a variety of crucial components to function properly. However, active components are more expensive than passive ones. This article explores the difference between the two types of electronics components. You’ll learn why active components are more expensive and why passive ones are cheaper.

Transistores

There are two basic types of electronic components: active and passive. Active components are used to produce power, whereas passive components are used to store it. Both types are important in electronic devices, because they ensure that the electronic equipment works as expected. However, there are a few important differences between active and passive electronic components.

A transistor is an active component, and it is a semiconductor device that requires external power to function. The transistor can boost or reduce the current that flows in a circuit. A transistor can also change the direction in which electricity flows.

Inductores

Active components are those that produce current or voltage, while passive components do not. The difference between active and passive components is not just in their physical appearance; it also has to do with their function. An active component has a function to amplify power, while a passive one has no purpose.

Essentially, active components require an external source of energy to work. Passive components do not generate energy, but they do store energy and control current flow. An example of an active component would be a transistor, while a passive component would be a resistor.

Inductors filter out high-frequency signals

An inductor can be used in an electrical circuit to filter out high-frequency signals. It works by reducing the frequency of the signal to a frequency lower than the input frequency. Generally, engineers look for a ratio that goes down to 1/(2*x)1/2. They also want to know the corner frequency, which can be determined graphically. The x-axis displays the frequency, while the y-axis represents the gain.

One way to determine the inductor’s inductance is by measuring the voltage across the inductor. This will help you to determine the sensitivity of the inductor to a high-frequency signal. The inductance can also be measured by using the corner frequency. Keep in mind that the inductance is not an exact measurement, because the circuit is always subject to loss.

Transistors are amplifiers and switches

Transistors are electrical devices used to control signals. They are made up of two basic components: an emitter and a collector. The emitter part of a transistor is forward-biased, and the collector part is reverse-biased. When a transistor is operating in its active region, the collector side will show a slightly curved curve. The collector region is the most important part of a transistor since it is where the collector current is most stable.

Transistors can be classified as either p-type or n-type semiconductors. When used as switches, they function in a similar way to amplifiers. They can act as switches by changing the current passing through the base.

Inductors are non-reciprocal

Inductors are non-reciprocal if two or more of them are connected in parallel, and there is no mutual inductance between them. This means that the sum of their total inductances will be less than the sum of their individual inductances. This is the case for parallel inductors, where the coils are arranged in opposite directions.

Mutual inductance is another way to define reciprocity. An equivalent circuit is one in which the primary and secondary portions are of equal mutual inductance. In a reciprocal transformer, the second part does not lose energy during magnetic coupling, so it does not represent lumped energy.

Inductors do not require an external source of energy

Inductors store energy by changing their magnetic field strength in response to the amount of current that flows through them. The stronger the current, the stronger the magnetic field, and the more energy is stored. This property is unique to inductors compared to resistors, which generally dissipate energy in the form of heat. In addition, the amount of energy stored in an inductor depends on the amount of current flowing through it.

The main purpose of an inductor is to store energy. When electric current passes through an inductor, a magnetic field is induced in the conductor. In addition to this, the induced magnetic field opposes the rate of change in current or voltage. As a result, a steady DC current will pass through an inductor, which is symbolized by the letter L. This property makes inductors useful in large power applications where they cannot be replaced with a conventional electrical component.

Las 3 principales causas y contramedidas de las deficiencias de pasta de soldadura en el diseño de placas de circuito impreso

Las 3 principales causas y contramedidas de las deficiencias de pasta de soldadura en el diseño de placas de circuito impreso

Las deficiencias de la pasta de soldadura en el diseño de una placa de circuito impreso pueden deberse a varias causas y medidas correctivas. Entre ellas se encuentran las juntas de soldadura frías, la colocación imprecisa, el exceso de calor durante la soldadura y las fugas químicas. He aquí algunas de las causas más comunes y cómo resolverlas.

Uniones soldadas en frío

Para evitar la formación de juntas de soldadura frías, los diseñadores de placas de circuito impreso deben diseñar la placa de manera que todos los componentes estén colocados en orientaciones similares y tengan buenas huellas de componentes. Esto ayuda a evitar problemas de desequilibrios térmicos y asimetría en las juntas de soldadura. También es importante diseñar las placas de circuito impreso de forma que cada componente se coloque en una almohadilla en forma de D. También es importante evitar el uso de componentes altos, ya que crean zonas frías en el diseño de la PCB. Además, es más probable que los componentes situados cerca del borde de la placa se calienten más que los situados en el centro.

Una unión soldada defectuosa puede ser el resultado de diversos factores, como la falta de fundente o una unión mal adherida. Un área de trabajo limpia es esencial para una buena calidad de la unión soldada. También es importante volver a estañar la punta de soldadura para evitar la oxidación.

Fugas químicas

Si es usted diseñador de placas de circuito impreso, quizá le interese saber cómo evitar las fugas químicas. Este problema está causado por las bolas de soldadura, que aparecen como pequeñas esferas de soldadura que se adhieren a la superficie del laminado, la resistencia o el conductor de una PCB. Debido al calor generado, la humedad próxima a los orificios pasantes de una PCB puede convertirse en vapor y extruir la soldadura.

El puente de soldadura es otro problema causado por una deficiencia de pasta de soldadura. Cuando la soldadura no puede separarse de un conductor antes de solidificarse, se forma un cortocircuito. Aunque los cortocircuitos suelen ser invisibles, pueden causar estragos en un componente. Hay varios factores que pueden causar este problema, como el número de patillas de una placa de circuito impreso, la distancia entre ellas y el ajuste del horno de reflujo. En algunos casos, un cambio de materiales también puede provocar puentes de soldadura.

Demasiado calor durante la soldadura

La pasta de soldadura puede ser propensa a deformarse cuando alcanza cierta temperatura durante la soldadura. Demasiado calor durante la soldadura puede provocar la formación de bolas de soldadura y deformaciones discretas. Un exceso de pasta de soldadura también puede provocar una desgasificación excesiva del fundente. Estos factores pueden contribuir a la formación de bolas de soldadura y deformidades en el diseño de PCB.

La pasta de soldadura nunca debe interactuar con la humedad. La máscara de soldadura debe colocarse correctamente y el fondo del esténcil debe limpiarse con regularidad. Otro error común en el diseño de PCB es el conocido como efecto lápida, o "efecto Manhattan", causado por desequilibrios de fuerza durante la soldadura. El efecto se asemeja a la forma de una lápida en un cementerio. Sin embargo, representa un diseño de PCB defectuoso con un circuito abierto.

Limpiar bien el material después de taladrar

La deficiencia de pasta de soldadura es el resultado de una limpieza inadecuada del material después del taladrado. El hilo de soldadura debe estar a la temperatura correcta y lo ideal es que esté completamente humedecido con las almohadillas y las patillas. Si la soldadura no se humedece adecuadamente, puede provocar la formación de un puente de soldadura u otros defectos. Se necesita la cantidad adecuada de soldadura para humedecer uniformemente las almohadillas y las patillas. Si no es así, puede formarse una capa de óxido metálico en el objeto unido. Esto puede solucionarse limpiando bien el material y utilizando el soldador adecuado.

Una soldadura insuficiente puede causar varios problemas en la placa de circuito. Una soldadura inadecuada puede causar un agujero de arena, una línea rota, un "agujero soplado" o un "vacío en la junta de soldadura". Una pasta de soldadura insuficiente también puede provocar la eliminación del estaño de los componentes. Es esencial evitar estos problemas siguiendo el proceso de diseño de la placa de circuito impreso.

Medidas preventivas

Los puentes de soldadura se producen cuando la soldadura entra en un espacio que no debería. Los puentes de soldadura pueden evitarse utilizando cables de componentes más grandes. Cuando las almohadillas son demasiado pequeñas, la soldadura tiene que mojar un área mayor y fluir un volumen menor por el cable. El resultado son bolas de soldadura que provocan cortocircuitos. Es importante colocar los pads en las posiciones óptimas y utilizar la pasta de soldadura adecuada en el proceso de soldadura.

La falta de pasta de soldadura en la placa también puede hacer que los cables de los componentes estén más calientes que las almohadillas, ya que los cables de los componentes tienen menos masa térmica y un mayor flujo de aire a su alrededor. Aumentar el tiempo de remojo de la pasta de soldadura evitará este problema e igualará las temperaturas en todo el conjunto. También reduce la tendencia de la soldadura a fluir hacia superficies más calientes. Otro método de prevención consiste en optimizar el diseño del esténcil para minimizar la cantidad de pasta de soldadura en las zonas problemáticas. Además de utilizar un esténcil, asegurarse de que los componentes no están dañados antes de su colocación puede ayudar a reducir la pasta de soldadura en las zonas problemáticas. También puede utilizarse el equilibrado de cobre para igualar el calentamiento y el enfriamiento de la placa de circuito impreso.
