After SMT Soldering Process is OverOnce the soldering process is over, the PCA or the PCB Assembly (PCBA) need to be washed to remove flux residues and any stray solder balls that could short out closely spaced component leads. This can be done with SMT solvent cleaning machine. Rosin flux...
Because of the widespread use of low solids or no-cleansolder flux, the use of nitrogen has become common for both wave soldering and reflow soldering processes. However, one should not expect nitrogen to be a panacea for solder defects. It will help only to the extent of its influence on...
Hold the chip in place while touching the corner pad with the tip of the soldering iron so that the solder melts the pin and the pad together. Check the alignment of the chip. If it is not in its place, use your soldering iron to loosen the pin chip and align the chip properly. Co...
Fixing solder bridges is not all that difficult but can be a bit tedious. The first thing to try is solder wick. I use the narrowest one I can find and a small tip on my soldering iron (I tend to use a higher temperature on the iron). Lay the solder wick across the offending are...
Re: EEVblog #415 - SMD Stencil Reflow Soldering Tutorial « Reply #25 on: March 03, 2013, 01:20:04 pm » Hi,Good video.I would very much like to make a ring light for my camera too. Is there any chance of getting the circuit diagram or pcb layout of the project in the...
Soldering the components I find it easiest to flux the pins, and add a single bead of solder on the board, keeping it molten you can then put the part in to place. Once secured its easy to solder all the other leads. This technique is used for all the parts going onto the board. ...

Often the biggest risk during re-work and repair is caused by leaving soldering iron on the pads for to long. This can give rise to damage month e board where pads can lift, and also within the resistor. Although he resistors are now more robust than they were years ago, caution ...
Anyway, in the beginning there were tweezers, a microscope, and a toaster over for reflowing. I very quickly realized that the tweezer method was insane to put it mildly, the only worst thing that I can think of is actually soldering everything with a soldering iron instead of using paste...
