Ya sea que sea un profesional o simplemente un aficionado a tiempo parcial, un elemento en el que puede considerar invertir es un horno de reflujo de soldadura para su trabajo de electrónica. Un horno de reflujo es parte del proceso para construir placas de circuito impreso (PCB). Sin embargo, hay varios factores que debe tener en cuenta antes de comprar un horno.
¿Qué es un horno de reflujo?
Un horno de reflujo es como un horno de convección que podría tener en su hogar. Tiene cuatro etapas de calentamiento: precalentamiento, remojo, reflujo y enfriamiento. El horno calienta y enfría la pasta de soldadura al rango de temperatura apropiado en una PCB. Esto se hace para mantener los componentes en su lugar en el tablero. Cada horno tiene su propio perfil de calentamiento y diferentes rangos de rendimiento.
Artículos a considerar al comprar un horno de reflujo
Hay tres factores principales a considerar al comprar un horno de reflujo: el perfil térmico, el costo y el tamaño del horno. El perfil térmico es el ciclo por el que pasa el horno con precalentamiento, remojo, reflujo y enfriamiento. El costo va de la mano con el perfil térmico. Si está buscando un horno de reflujo donde pueda personalizar el perfil térmico, entonces un modelo de gama alta es su opción. Obviamente, los modelos de gama alta son caros. Sin embargo, si eres un profesional, definitivamente vale la pena invertir en un modelo de gama alta.
La otra opción a considerar es el tamaño del horno. Nuevamente, el costo juega un papel aquí. Si va a trabajar en varias tablas a la vez, un horno más grande podría ser mejor. Por otra parte, si esto es simplemente un pasatiempo para usted, entonces un horno de menor tamaño funcionará perfectamente bien. Al final, todo realmente depende de lo que pretendes hacer con tus placas de circuito. Los hornos más grandes y de alta gama van a resultar en un producto de mejor calidad, pero los hornos más pequeños que realmente solo pueden hacer un perfil térmico pueden ser igual de eficientes cuando se usan correctamente.
El mejor horno de reflujo para soldar
SMTHouse T962 Horno de reflujo
los T962 Reflow Oven is an infrared unit capable of outputting 800 Watts of power. It has a surface area of 180 by 235 millimeter. The T962 has temperature ranges from 100 to 350 degrees Celsius. It also has a cycle time of one to eight minutes. In addition, it can solder single and double circuit boards in various encapsulation forms.
The T962 comes with eight pre-programmed thermal profiles that should fit a variety of PCB designs. It has a LCD screen that is easy to use and a built-in keypad. It circulates the heat and air quickly and efficiently for an even temperature. The T962 also has a single door with a window that holds the PCB board in place. An individual can use the window to observe the soldering process. One other nice feature is that this unit has a built-in exhaust fan for soldering.
While this was a relatively popular model for the features that were provided, there were a few notable complaints. One complaint related to the ineffectiveness of the LCD screen and how half of it was not usable. The other related to a hot spot within the unit using the third wave function. It ended up burning the PCB.
SMTHouse T962A Horno de reflujo
Este es otro SMTHouse product that is similar to the T962. The T962A is an infrared unit that is capable of outputting 1500 Watts of power. It has a temperature range of 100 to 350 degrees Celsius. In addition, it has a cycle time of one to eight minutes. It can also manage PCBs that are single and double soldered. The T962A also has an LCD screen for programming and ease of use.
The biggest advantage this unit has over the T962 is that it has more surface area. It has a soldering area of 300 by 320 millimeters. Depending on the board size, it can do more than one at a time. It also has eight pre-programmed thermal profiles just like the T962. As with the other model, the T962A produces an even heat flow for accurate temperature cycles for a variety of PCB sizes.
This product was slightly more popular that the T962 and did not have any overly negative reviews. However, we did note that one professional complained that this unit did not handle larger boards as well as it claimed.

The 5040-XR3 kit comes with pretty much anything you would need to do a complete soldering job. An added bonus is the warranty on this unit.
One negative of this unit is that it is not a complete reflow oven. It only really handles the pre-heating cycle of the thermal profile. If you are looking for an overall complete kit, this is not it. However, it is close. Most reviews of this unit were positive and the only negatives related mostly to power output not being at the high range as expected.
Horno de reflujo ChefStore
The ChefStore is capable of outputting power of 2900 Watts. It is an infrared unit that has a 400 by 600 millimeter surface area. It can handle PCBs throughout an entire thermal profile. It can output temperatures from 100 to 350 degrees Celsius. It also has a cycle time of one to eight minutes.

The size is definitely a negative as this is only intended for small batch projects. In addition, it is intended for lead-free solder and will not work well with lead-based. For the most part, this unit has relatively positive reviews and nothing majorly negative about it.
Máquina de soldadura por reflujo QS-5100
los QS-5100 is another model intended only for lead-free soldering. It utilizes infrared heating to work through an entire thermal profile. It has a precise controlled microcomputer that ensures an even heating and cooling cycle and outputs a quality PCB. The soldering surface area on this unit is 180 by 120 millimeters.
This is another smaller unit for smaller PCBs. It has a programmable LCD display and an even thermal profile. It is capable of working off 110 or 220 volts. Users found it outputted mostly consistent heat as described and that the size was ideal for smaller board designs.
This unit has mostly positive reviews and only a few minor notes. Users did find that they had to play with the temperature settings a bit to get a good product. It seemed to be off by about ten degrees, but that was easily fixed in programming. In addition, users recommended using this in a well-ventilated area due to a slight smell.
Horno de reflujo SMTmax AS-5060
The AS-5060 reflow oven is capable of heating to a temperature of 300 degree Celsius. It has a soldering surface area of 305 by 320 millimeters, which makes it one of our larger units. It also has a shorter cycle than other models and runs from zero to thirty seconds.

There were no negative reviews of note for this unit. Overall, it is a good unit for larger batches and circuit boards. Being programmable is also a huge plus.
If you are an electronics hobbyist or even a professional, a reflow oven is a nice piece of equipment to have for circuit board soldering. They are similar to a convection oven and got through a four temperature thermal cycle that allows for heating, soaking, reflowing, and cooling. It is good to consider what you overall usage is going to be with your reflow oven because they come in a variety of sizes and power outputs. Some can only handle smaller boards, while others can do larger boards or batches of PCBs. If you are looking for something to use in a more professional capacity, it is probably best to consider a large unit that can handle more boards at a time. In addition, some of the units are programmable and can be inputted with specific solder paste parameters. Others come pre-programmed with a set amount of profiles and might be better suited for hobbyists. Another factor to consider is the thermal profile cycle speed. On average, most of the units take from zero to eight minutes depending on the thermal profile. Some other units are capable of cycling through at a much faster rate. As always, we recommend reading online reviews and getting a sense of what users have to say about any reflow oven you might be considering.
