The difference between reflow soldering and wave soldering, what is the difference between reflow so

The process is different! To put it simply, wave soldering is a plug-in process, and reflow soldering is a patch process! Specifically, take a look at the encyclopedia!

Both of these devices are soldered circuit boards. Wave soldering is a machine for soldering plug-in component circuit boards, and wave soldering requires the addition of solder. Reflow soldering is a machine for soldering the circuit board of the SMD component, and reflow soldering does not need to add solder, because the solder paste is already printed on the board before the SMT.

Reflow soldering is just a lot of temperature to heat to solder.

In terms of soldering cost and density, the reflow soldering process is more advantageous, but at present, the wave soldering process of high-power devices, large-capacity devices and high-strength connection devices cannot be replaced for the time being, so it should be said that each has its own advantages, and its existence is reasonable!

In addition, the through-hole process does not represent the wave soldering process, because wave soldering is only a piece of equipment, and there are automatic dip soldering machines and selective soldering, which are through-hole soldering processes, and you can choose related equipment according to your product needs!

Hello, wave soldering is mainly used for soldering inserts.

What are the advantages of reflow soldering main soldering SMD components? You all know that the use is different, how to compare the advantages?

Until now, wave soldering is still like that, and there will be no major changes in the future, and reflow soldering will be the same, and no new technology will appear.

As for the ** There is a big difference Domestic ones are generally more than a dozen to hundreds of thousands, Japan is a good one, and there are one hundred thousand good ones in Europe and the United States.

To put it simply, reflow soldering is used to solder SMD components on the PCB board, and wave soldering is the soldering of plug-in components on the PCB, both of which are soldering of components and PCBs in advance, but the corresponding component packaging methods are different from the PCB designed by the designer. Hope it helps.

Reflow soldering: It refers to the electrical interconnection between the pins or solder terminals of electronic components pre-mounted on the pads and the pads on the PCB by heating and melting the solder paste pre-coated on the pads, so as to achieve the purpose of soldering the electronic components on the PCB board. Reflow soldering is generally divided into a preheating zone, a heating zone, and a cooling zone.

Reflow soldering process: printing solder paste, mounting components, reflow soldering, cleaning.

Wave soldering: A pump is used to jet molten solder into a solder crest, and then the pins of the electronic components that need to be soldered are passed through the solder crest to realize the electrical interconnection of electronic components and PCB boards. A wave soldering is divided into four parts: spraying, preheating, tin oven and cooling.

Wave soldering process: plug-in, "apply flux", "preheat", "wave soldering", "cut off corners" and check.

Difference Between Wave Soldering and Reflow Soldering:

1) Wave soldering is the formation of molten solder to solder crest to solder components; Reflow soldering is the formation of reflow melting solder at high temperature, hot air sparrow bonds, and soldering components.

2) When reflow soldering, there is already solder before the PCB is put on the furnace, and the coated solder paste is melted and soldered after soldering, and the solder generated by the soldering machine is not bright before the furnace, and the solder wave generated by the welding machine coats the solder on the pad that needs to be soldered to complete the soldering.

3) Reflow soldering is suitable for SMD electronic components, and wave soldering is suitable for pin electronic components.

Landlord is good, these are two different ways of welding, you can learn about it.
