ETA Senior Engineer Tell You How to Choose the Reflow Soldering Oven -- Chapter 1
High performance reflow oven, available in 6 zones, 8 zones and 10 zones. PC + Siemens PLC control system, first-class heating module. the reflow soldering oven important parts use famous brands such as Japan and Germany.
Some clients let us teach them how to choose the reflow oven, and some clients' engineer think use 6 heat zones or 10 heat zones is all the same result.
Today we will give you some details about the reflow oven different and how to choose.
The purpose of reflow oven is to heat the solder paste, let it melt, and solder the components to the PCB board. So the solder paste is our engineer focus.
First, the solder paste contains alloy and flux, and most the solder paste have more than a half is flux. The flux's melting point is lower than alloy, we need to control the temperature the time of flux melt and volatilize. When the flux volatilize, the time of the alloy melt is also need to be controlled.
As a result, engineer around the world calculate the time of the every PCB board in reflow oven is about 210 second.
That means every reflow oven's chain speed must control neither to fast nor to slow. Many client's bought the 6 zones reflow oven, and want to increase the capacity of product. Our answer is no, if you do that, your time of flux and alloy melt will not enough and your product must have many problem.
The above is how to choose the reflow oven according to your product capacity. According to how many product you want to make, you can calculate you will buy 6 zones, 8 zones, 10 zones, or 12 zones.
