There are several motors for reflow soldering, what are their functions? How many temperature zones are there, and what is the temperature?
What is reflow soldering? Reflow soldering refers to the use of solder paste to connect one or more electronic components to the contact pads, and to melt the solder through controlled heating to achieve permanent bonding. Different heating methods such as reflow ovens, infrared heating lamps, or...Read more -
What are the specific temperature zones for SMT reflow soldering? The most detailed introduction.
Chengyuan reflow soldering temperature zone is mainly divided into four temperature zones: preheating zone, constant temperature zone, soldering zone, and cooling zone. 1. Preheating zone Preheating is the first stage of the reflow soldering process. During this reflow phase, the entire circuit b...Read more -
The working principle of wave soldering, why use wave soldering?
There are two main methods of soldering commercially – reflow and wave soldering. Wave soldering involves passing solder along a preheated board. Board temperature, heating and cooling profiles (non-linear), soldering temperature, waveform (uniform), solder time, flow rate, board velocity, etc. a...Read more -
What is the reason for wave soldering with tin? What is the effect? How to adjust?
Many friends of wave soldering have tin-connected situations when using wave soldering, which is very troublesome. The main reasons for this situation are the following: Flux activity is not enough. Flux does not wet enough. The amount of flux applied is too small. Uneven flux application. The ci...Read more -
SMT reflow soldering temperature curve
Reflow soldering is a crucial step in the SMT process. The temperature profile associated with reflow is an essential parameter to control to ensure proper connection of parts. The parameters of certain components will also directly affect the temperature profile chosen ...Read more -
