The pick and place machine places the components onto the board, and it can remain in place with the surface tension of solder paste.
#Reflow solder paste manual#
As usual using the automatic pick and place machine as it can’t work when using the manual placement to the numbers of components and necessary accuracy. Pick and place : it can fix the components in place with the solder paste on the board. Then having been added the solder paste to the board after adding, it can go on to the next stage. And it only allows the solder paste to be added to the PCB areas where it’s required. There is the solder resist layers on the board, but it’s essential to only add solder paste to the areas that require soldering, which is done by using the solder mask and solder paste machine. And the solder paste is only used for the areas that require soldering. Solder paste : substantively applying the solder paste to the board. Now PCBGOGO will explain the stage what is it. Use the solder paste and components to the board is the first stage in reflow soldering for PCB assembly. And it’s the best for use with components used in mass produced electronics products. Reflow soldering technology, making it possible to reliably solder surface mount components, especially the components with very fine pitch leads. What’s more, heating can be done by passing the assembly with the reflow oven as well as under an infrared lamp or by soldering individual joints with a desoldering hot air pencil. The solder paste reflows in a molten stage to create the permanent solder joints. Reflow soldering is a process, which using the solder paste to connect one or thousands of tiny electrical components to their contact pads, and then it will control the whole assembly by heating. The purpose of reflow soldering is to be acceptable soldering joints with pre-heating the components/PCB/solder paste first and then melting the solder, which instead of overheating without damage. It offers credible soldering for the all kinds of the sizes of component and pad required, as well as making it easy to control. When it comes to PCB assembly process, reflow soldering is the most widely used method of soldering, which is widely used for PCB assembly. Explaining Reflow Soldering for PCB Assembly by PCBGOGO
