How to choose reflow soldering? The first consideration is the reflow soldering factory. Only qualified equipment can guarantee the authenticity, high quality, low price and after-sales service.

One. Look at the appearance volume.

The reflow soldering machine is carried out by the action of high temperature. The longer the reflow soldering machine, the better the welding effect. Therefore, the larger the reflow soldering machine, the larger the heating area. The heating effect is higher. Due to too much competition in the domestic market, the price of materials is rising! Some manufacturers save money in this regard, reflow soldering phase, smaller size. Save material costs and reduce costs! So when buying reflow soldering, first look at a few temperature zones, then look at the heating length. For the same price, the longer the heating section, the higher the price-performance ratio!

Second, look at the liner

The production process of reflow soldering machine has been improved and constantly innovated. The domestic reflow soldering machine already has a skilled technical foundation, but the cost of a well-made product must be increased, such as the furnace liner. In the past, because there was no fan in the furnace lining, the PCB was directly heated by the heat dissipation function of the heat pipe, called infrared heating. Later developed into hot air heating, that is, adding a drilled aluminum plate in front of the heating body, the hot air will be blown out from the hole, thereby making the heat treatment effect of the PCB more uniform! Later, it was improved to a more advanced thin tube blowing, called hot air microcirculation, which cost more. Currently, many manufacturers are manufacturing furnaces.

3. Look at the fever part

As long as you open the lid and open the furnace, you can see the heating body. Generally speaking, due to the limitation of the peripheral size, the heating tube is used for small reflow soldering. There are two types of heating pipes. One is with a radiator, the other is a light rod type. The performance of the radiator type is better than that of the polished rod type. Medium and large reflow soldering uses heating wire, high heat exchange rate and long service life. Reflow soldering furnace temperature test method.

4. Transmission and Transportation

Conveyor belt vibration can cause welding spot displacement, suspension bridge, cold welding and other welding defects

5. Professional testing and evaluation

In addition to the above intuitive selection methods, there are some professional tests and evaluations. Whether reflow soldering equipment can be included in the procurement plan, and consider some operating parameters
