7 Simple PCB Board manufacturing tips- (DIY Pcb 2020)

Basic skills for successful Printed circuit board design

fabricación can be a very complex or detailed process. Each stage of circuit board assembly needs to be performed in the correct order to ensure maximum efficiency and continuous function of the pcb board.

This will not change when outsourcing the circuit board assembly to the circuit board proofing manufacturer. Moreover, before starting to manufacture printed circuit boards,

Here are some fabricación tips to ensure that everything goes smoothly.

1. Plan ahead: Before starting to send any PCB design to a reliable circuit board proofing manufacturer, make sure you have planned all aspects of the ordered design. This includes:

• contacting the PCB manufacturer and
• explaining the assembly time.

Some printed circuit board manufactures provide a general delivery time of 5 days or less, which is 75% faster than the pcb industry average production capacity.

2. Triple check design:to ensure that the design meets the standards of the final product. A fabricaciónshould include multiple rounds of modifications to ensure that the design meets the requirements. For example, a printed circuit board with a complex design and a large number of through holes for high-tech products are important.
3. Full label design:Even if the design has been checked many times before being sent to the circuit board proofing manufacturer, it may accidentally forget the correct label. Similarly, ensure that all components are properly labeled to reduce misinformation.
4. Keep in touch:keep in touch with manufacturing partners throughout the PCB manufacturing process. This ensures that something in the design needs to be changed. And the manufacturer can be notified quickly.

Furthermore, communication is an important part of the entire process and can help ensure satisfaction with the final product.

ways to assemble DIY circuit boards for projects- PCB Board manufacturing

Hay varias formas diferentes de ensamblar placas de circuito de bricolaje  para proyectos. Cada uno tiene sus propias ventajas y desventajas. Las tarjetas perforadas y otros productos similares se pueden utilizar para fabricación . Que no requieren un aspecto profesional, y modelos de tablero Adecuado para la construcción de circuitos prototipo.

Cuando un proyecto requiere un aspecto más profesional, también es posible hacer placas de circuito impreso con sus propias manos a partir de:

• materiales adecuados
• equipo adecuado.

Generalmente, la mejor manera de construir este tipo de placa de circuito con sus propias manos es imprimir el diseño en la pieza de trabajo usando una impresora láser. Que está sobre una pieza de cobre. Y luego grabe la pieza de trabajo con una solución de cloruro de hierro. Se pueden lograr resultados similares con un PCB terminado, si lo hubiera.

Why designing is important in PCB Board manufacturing?

Pcb board manufacturers design Printed circuit boards to provide electrical communications and support for electronic components. Simultaneously, usually they use copper to electrically connect the components. And they also use several non-conductive substrates.

Commercially made printed circuit boards are usually etched. Although some are created by adding copper tracks to a non-conductive substrate. There are several ways of fabricación :

 It includes a method that can lead to engraved boards that have a pretty professional look.

Para hacer una mejor placa de circuito impreso con sus propias manos, debe considerar un proyecto específico. La opción más sencilla para construir los circuitos usted mismo es simplemente utilizar un "diseño" comercial. Dado que estos dispositivos están diseñados para prototipar rápidamente nuevos circuitos.

Las tarjetas perforadas son otra opción que te permite montar tú mismo rápidamente las tarjetas, aunque los resultados no suelen tener un aspecto profesional.

Una forma de hacer una PCB de aspecto profesional con sus propias manos es utilizar una PCB lista para usar. Suele ser un dispositivo de control numérico por computadora (CNC) que utiliza instrucciones de diseño automáticas (CAD) para cambiar automáticamente el circuito en una pieza de tocho de cobre. Del mismo modo, si el molino de PCB no está disponible, también puede utilizar el proceso de decapado para mantener un fabricación de la placa de PCB .

La importancia del grabado en la fabricación

Los materiales y equipos necesarios para grabar una placa de circuito impreso con sus propias manos incluyen:

• una impresora laser
• papel brillante
• Hierro
• espacios en blanco de cobre y
• una solución de cloruro de hierro.

Este proceso implica imprimir una imagen reflejada del circuito. Y transfiriéndolo a un trozo de lingote de cobre con calor de hierro. Luego, el papel se puede quitar con agua. Y puede colocar el tocho de cobre en una solución de cloruro de hierro (III). Se llevará a cabo en la superficie sin problemas.

Uno de los consejos importantes para mantener este tipo de fabricación  es buscar papel brillante que no sea resistente al agua. El papel de revista suele ser una buena opción. Dado que las revistas generalmente se imprimen con tinta en lugar de tóner.

Análisis de las habilidades de cableado de la placa de circuito de PCB

PCB is also known as a printed circuit board. Which can realize the circuit connection and function realization between electronic components. And is also an important part of the power circuit design in fabricación.

The general principle of multi-layer PCB circuit board layout and wiring are as follows:

fabricación rules for setting the distance between printed traces of components

The spacing constraint between different networks is determined by the:

• electrical insulation
• manufacturing process, and
• Componentspacing of printed traces for components.
• Size and other factors.

For example, the pin spacing of a chip component is 8mil. The Clearance Constraint of the chip cannot be set to 10mil. And the PCB designer needs to set a 6mil PCB design rule for the chip separately. Furthermore, at the same time, the setting of the distance should also take into account the production capacity of the manufacturer.

In addition, an important factor that affects components is electrical insulation. If the potential difference between two components or the network is large, pcb board manufacturer should consider electrical insulation.

In fabricación the gap safety voltage in a general environment is 200V / mm. Which is 5.08V / mil. Therefore, when there are both high-voltage circuits and low-voltage circuits on the same circuit board, it is necessary to pay special attention to the sufficient safety distance.

When there are high-voltage circuits and low-voltage circuits, it is necessary to pay special attention to the sufficient safety distance.

Anti-interference and electromagnetic shielding of printed wires in fabricación

The interference on the wire mainly includes the interference introduced between:

• the wires
• the interference introduced by the power cord
• the anti-interference and
• electromagnetic shielding of the printed wires.

The interference on the wire mainly includes the interference introduced:

• between the wires
• the crosstalk between the signal lines, and
• the crosstalk between the signal lines.

The reasonable arrangement and layout of wiring and grounding methods can effectively reduce the source of interference. And make the PCB design the circuit board has better electromagnetic compatibility performance.

In fabricación, for high-frequency or other important signal lines, such as:

• clock signal lines
• on the one hand the traces should be as wide as possible, and
• for high-frequency or other important signal lines,

How to maintain corner alignment in PCB Board manufacturing?

The choice of line corner alignment

In order to make fabricación de la placa de PCBprocess easy and beautiful, it is necessary to set the corner mode of the circuit. And the choice of the form of the corner routing of the circuit during PCB design. You can choose 45, 90 and arc.

Generally, sharp corners are not used, and it is better to use arc transition or 45 transition. And avoid 90 or more sharp corner transition. The connection between the wire and the pad should also be as smooth as possible to avoid the appearance of small pointed feet. Which can be solved by the method of supplementing teardrops.

When the center distance between the pads is less than the outer diameter D of a pad, the width of the wire can be the same as the diameter of the pad. yof the center distance between the pads is greater than D, the width of the wire should not be greater than the pad diameter.

When the wire passes between the two pads and does not communicate with it, it should maintain a maximum and equal spacing with them. Similarly, when the wire and the wire of the wire pass between the two pads without communicating with it, it should maintain the maximum with them.

And the equal spacing, the spacing between them should also be even and equal and keep the maximum. The spacing between them should also be uniform and equal and keep the maximum.

Conclusion- PCB Board manufacturing

The above is the general principle of PCB Board manufacturing layout and wiring. But in actual operation, the layout and wiring of components is still a very flexible work. The layout and wiring of components are not unique. And the results of layout and wiring are very to a large extent still depends on the experience and ideas of PCB designers.

It can be said that there is no standard to judge the right and wrong of the layout and wiring scheme. Only the relative advantages and disadvantages can be compared. Therefore, the above layout and wiring are only for PCB design reference, and practice is the only criterion for judging the merits.
