- Why and when to use reflow soldering?
Reflow soldering techniques are used for surface-mount parts Whilst most surface-mount boards can be assembled manually using a soldering iron and solder wire, the process is slow and the resultant boards can be unreliable Modern PCB assembly facilities use reflow soldering exclusively for large-scale production, with pick and place machines putting the components onto the boards, which have

The reflow soldering process is designed to avoid these problems This is the temperature profile of a typical reflow soldering process: (source: apemswitches be) The idea is to pre-heat the whole board to a high, but safe temperature
- components - Using a home oven for solder paste - Electrical . . .
Reflow is done using two temperatures, a pre-soak temperature and a reflow temperature as shown below As such, you REALLY need to use two ovens to do this right, quickly switching it from one to the other after the pre-soak time
- How to solder two-sided PCB - Electrical Engineering Stack Exchange
I am wondering how can I reflow two-sided PCBs I have read many methods on the Internet like use two soldering pastes with different reflow temperature, using roaster oven, etc
- pcb assembly - Excessive brown flux post reflow - Electrical . . .
Place components Reflow Spend a long time cleaning and inspecting The paste used in the examples below is SMD291AX from Chipquick, it's a leaded, no-clean flux solder paste In this example, it was a fresh tube that arrived that morning My reflow oven is homemade, but the profile tracks the recommended profile pretty well, within a few degrees
- soldering - BGA reballing and reflowing, how to actually repair dead . . .
To my understanding BGA reflowing is a technique which aims to reconnect bad solder joints on a BGA chip, BGA reballing is a technique to desolder and then resolder a BGA chip both aim to do the same
- Hot Air Gun for Reflowing a Board? - Electrical Engineering Stack Exchange
Start the hot air gun and slowly sweep it over the board as the paste reflow I could utilize a fixture like this to keep the gun perpendicular to the board and just move the gun in the x-y plane
- Reflow temperatures vs chip removing temperature - Electrical . . .
Is "Reflow Temperature" the same as "Chip Removing Temperature"? It says lead free solders melt at 250C I tried to remove a chip at this temperature and heated it for 30 minute
