Some solder will contain a small amount of silver. This pushes the melting temperature up a bit, but the silver helps the solder to flow and makes a stronger joint. If you are worried about burning whatever your working with, try to stay away from solder with silver in it, but it works...
In electronics PCB Manufacturing, Assembly and Rework, the metals to be joined are the leads of the electronic components (thru-hole or SMD) with the copper tracks on the PCB. The alloy used to join these two metals is solder which is basically tin-lead (Sn-Pb) or tin-silver-copper (S...
Lead-free solder is very similar to its leaded counterpart, except, as the name states, it contains no lead. Instead it is made up of mostly tin and other trace metals, such as silver and copper. This solder is usually marked with the RoHS symbol to let potential buyers know it conforms...
the lower quality parts don’t have this. The image of the sectioned crimps shown make this obvious, but to determine this when not sectioned, look down the barrel of the crimp from the wire entry end. You will see metal to almost the end of the crimp in a...
And second, is this a drop-in replacement, just solder the modern ringer in place of the bell and it will work, or is it more complicated than that? And finally, are there instructions out there on the net for doing something like this and I just haven't found the magic search term...
If you need to replace the DC power jack, you’ll find it mounted in the top right corner of the base. In a HP Pavilion dv5 laptop the power jack is not soldered to the motherboard. It’s attached to a power cable. STEP 31. ...
5) Visually inspect where the wires are soldered to the coil. It is not unusual to see many of the wire strands broken off. The more that are broken off, the higher the resistance which will reduce flipper power. 6) It could be the power supply to the flipper. Check for burnt connec...
My Pavilion DV7-1451nr isnt charging, the power LED on the laptop isnt turning on, we got a new AC adapter for it thinking that was the case, and it wasnt…it isnt the battery, a guy was telling us it could be the solder or something, not too sure what he said, if it were the...
e) The solder under the hot air gun turns silver. Be patient! You will see the flux smoking. Keep hovering another 10-20sec and gently touch the part. If it moves, pick it up, or push it off the empty area of the board.
Moving back to the bottom of the lamp, cut the cord a few inches away from the base. (Scary, I know! But we’ll get this bad boy working in no time.) And pull the wires apart: Using a wire stripper, strip the ends of each wire: Now you’re going to solder the ends of these...
