What is solder mask for printed circuit board? Learn how to make one.

The Printed Circuit Board is an essential part and used in virtually all electronic projects. To improve its operation and bring a differential to your board, printed circuit board suppliers advise to use solder mask. It brings perfection to the project

What is solder mask?

The solder mask for the printed circuit board is a cover formed by paint or other material that stands out on the board in order to differentiate the circuit from the rest of the board.

It can be done in several ways and still has several functions within a PCI. The problem is that the steps to be taken are very susceptible to small errors that can hinder the functioning of your circuit.

What is its importance for printed circuit board suppliers?

An essential function of the printed circuit board solder mask is to facilitate when soldering the components at the terminals. Since the solder cannot adhere to the paint used in the mask.

Hay otra función importante. La máscara de soldadura es capaz de proteger los elementos conductores de los daños provocados por agentes externos, como la humedad. Es por eso que la mayoría de los proveedores de placas de circuito impreso lo use it in their projects.

¿Qué materiales se necesitan?

A pesar de la larga lista de materiales necesarios para hacer la máscara, la mayoría son bastante fáciles de conseguir e incluso puedes tenerlos en casa.

Aquí está la lista de materiales necesarios:

• Papel de transparencia A4
• Lana de acero, Detergente
• Pegamento caliente, eje de molienda
• Tinta fotosensible
• Rectificar, placa de vidrio
• Espuma de poliestireno, lámpara UV
• Solución de carbonato de sodio al 1%;

¿Cómo fabrican los proveedores de placas de circuito impreso la máscara de soldadura?

To make the mask, the procedure is very similar to making the plate itself, removing the final part of the job. los proveedores de placas de circuito impresosuggest several ways to make the printed circuit board mask.

A photolith should be created with the tracks and the position of all the components of the board. To do this, we have the help of some specific software for this;

2. Next, we must print the photolithography on transparent paper. It is recommended to print first on a sheet of plain paper to see the position of the holes. Moreover, it is very important to wash the plate with steel wool and detergent. It is to remove the remaining impurities.
3. Con el pegamento caliente, debe conectar un husillo de pulir en el centro de la parte posterior de la placa. Y luego pase la tinta fotosensible por la parte superior de la placa. Según Proveedores de placas de circuito impreso , no olvides usar el guante.
4. Después de pasar la pintura, centrifugue la placa con el molinillo dentro de una caja de cartón para eliminar el exceso de pintura. Un consejo es encender y apagar rápidamente la amoladora para que el eje no se desconecte de la placa.
5. Retire el eje de molienda y cure la placa con un secador de pelo durante 20 a 30 min. Con la placa ya seca, colocar el fotolito sobre la placa y presionarlo para mantenerlo fijo. Con esto, coloque la placa de vidrio sobre la placa de circuito y aplique presión con la placa de vidrio para eliminar las burbujas de aire que puedan existir.

¿Cómo reparan los proveedores de placas de circuito impreso la lámpara de la máscara?

6.   Fije la lámpara dentro de la espuma de poliestireno y ciérrela con la placa de circuito y el fotolito adentro. Recordando mantener la placa de vidrio encima de ambos. Después de cerrar la espuma de poliestireno, los proveedores de placas de circuito impreso encienden la lámpara y la mantienen encendida durante 10 a 12 minutos.
7. Después del tiempo previsto, abra la espuma de poliestireno y retire la placa de vidrio con el fotolito y la placa de circuito. Separe el fotolito de la placa.
8. En un recipiente de plástico, coloque la solución de carbonato de sodio al 1% y deje el plato dentro de esa solución durante 1 minuto.

9. Finalmente, pase un rodillo de pintura sobre la placa mojándolo en la solución hasta que salga el exceso de pintura. Detente cuando veas exactamente lo que hay en el fotolito.
10. Después de todos estos pasos, la máscara de la placa de circuito impreso estará lista.

Printed circuits were first used more widely around 1943. During the military conflict, they were used in radio equipment. They were essential for extremely conflicting situations during that period.

After World War II, printed circuits were used in other applications. And, with the implementation of transistors, they became the most common form of building transistor circuits.

Currently, Proveedores de placas de circuito impreso provide pcb for all types of electronic equipment used in everyday life.

History of welding process in printed circuit boards

Electrical circuits are present in practically all the equipment and products we use in our daily lives. And their trend grows more and more as technology advances. However, it was not always like this.

The first electronic circuits did not have as much complexity and resources as what we have today. They were mounted on supports and metallic pedestals. Here the electronic components were fixed on a bakelite base with solder pins to allow the soldering of its terminals. They were assembled using only manual processes, such as radios, TVs and record players.

This technology aims to reduce the space occupied by traditional components. Despite the maintenance of these boards become more complicated due to their size, they gain in terms of quality and reliability. It means that their error rate is much lower.

Como ya hemos visto anteriormente, el uso de la tecnología PTH y SMD puede garantizar varios beneficios para Proveedores de placas de circuito impreso . Haciéndoles observar de forma rápida y precisa los resultados que puedan obtener.
