Is there a 12 zone reflow oven in China What is the quality 5

It has been there for a long time, but there are not many reflow soldering in the 12 temperature zone, so it is recommended to choose Shenzhen Etta and Jintuo!

Hello, there are reflow soldering in the domestic 12 temperature zone, but there are more reflow ovens with eight temperatures as standard, and the 12 temperature zones need to be customized, we are a professional equipment manufacturer, you can send product samples and production requirements to my mailbox Rio Tinto Chen Jian to help you!

ETA's 12-zone stove is ok, but it's still a little worse than the imported one!

ETA's 12-zone reflow soldering can be done!

Some. That's a lot! Now the 8 temperature zone is not very popular, and there are more than 10 districts and 12 districts.

The quality is good!

We use the 12-temperature zone reflow soldering of Shenzhen ETA, and we now make Apple's iPad and Mac.

12 temperature zone reflow soldering recommended to choose Jintuo, ETA, Cologne! To the product ***!

12 temperature zone reflow soldering preferred ETA, Shenzhen!

It seems to be like this: 2svafixf684780 random sentence sample random sentence 2 sample before title sample after title.

From the machine, there are: three-temperature zone reflow soldering, five-temperature zone reflow soldering, eight-temperature zone reflow soldering, ten-temperature zone reflow soldering, twelve-zone temperature reflow soldering, etc.;

In terms of technology: there are preheating area, constant temperature area, welding area and cooling area.

1.Preheating area: PCB and material (components) preheating, for the reflow oven is the heating effect of the first one to two heating intervals Higher preheating, so that the soldered material reaches thermal equilibrium, the solder paste begins to move, and the flux and other components are affected by the temperature rise and begin to volatilize appropriately, which is the heating effect of the third to fourth heating interval for the reflow oven

2.Constant temperature zone: Removing the oxide on the surface, some of the gas flow begins to evaporate (start welding) and the temperature reaches the melting point of the solder paste (at this time, the solder paste is in the state of dissolving but not dissolving), which is the heating effect of the fifth, sixth and seventh heating intervals for the reflow oven

3.Soldering zone: from the melting point of the solder to the peak and then to the melting point, the process of solder melting, the pad and the solder form a weld, which is the first for the reflow oven.

Eighth, ninth, tenth, three plus interval heating

4.Cooling zone: from the melting point of the solder to about 50 degrees, the formation process of alloy solder joints, which is the first for reflow ovens.

Ten. 1. The cooling effect of the two cooling intervals.

From the device. Reflow soldering is now popular in the market is 8 temperature zones and 10 temperature zones, each temperature zone is divided into 2 temperature zones, that is, 1 temperature zone, 1 temperature zone, 2 temperature zones, 2 temperature zones... And so on.

Older models of machines have temperature zones.

There are older machines that are 3 temperature zones, 4 temperature zones. All are desktop models, i.e. there is only one upper zone per zone.

There are some furnaces that are customized by the customer, and I know that there are 19 temperature zones, i.e. a total of 38 upper and lower temperature zones.

From the process. 4 districts.

Preheating zone, baking board, evaporation point flux

Constant temperature zone Slowly warmed, flux volatile activity.

Soldering area The solder paste is melted and soldered into shape.

Cooling zone Cooling substrate.

Hello! It is divided into 4 zones: preheating zone - holding zone - welding zone - cooling zone.

Shenzhen is ETA Electronic Equipment****.

No. 3, 3rd Road, Yangchong Industrial Zone, Shapu, Songgang.

Now lead-free reflow soldering is generally more than 8 temperature zones, and the main purpose of increasing the reflow soldering temperature zone is not to better the welding effect as generally recognized, but mainly to improve the efficiency of reflow soldering, that is, to improve the welding speed of reflow soldering, if you do not pursue the output, the general 8 temperature zone can be.

There are 10, there are 8, which is the most used, and there are 12, 6.

If the reflow soldering temperature is too low, the solder paste dissolving temperature is not reached, and the soldering will not be soluble, the soldering will not be successful, the soldering will be uneven, and the soldering will not be possible.

It is recommended that you purchase a better German wickon furnace temperature tester to test the furnace temperature, so as to adjust the reflow soldering equipment setting temperature according to the actual furnace temperature measured by the furnace temperature tester, so that the reflow soldering can really reach the ideal welding temperature. If it really doesn't work, the manufacturer of reflow soldering will come back to you for debugging, and if you don't understand anything, you can call DH: 158---1401--5885

I can come and test it for you.
