    Soldering Iron Temperature for Lead Free Solder (Sn99.3%, Cu0.7%)

    Recently I bought this lead free solder (Sn99.3%, Cu0.7%), D0.6mm. I have seen many suggest at least 350°C for soldering iron. But I tried at around 225°C (between 200°C - 250°C), the solder still melt well. (All shinny surface) (Some dull some shinny) Funny...

    AC adapter broken after repairing cable

    Hello, I had an old AC adapter (230V AC to 14V DC). There was a small part where the insulation of the cable was damaged. You could see the copper coming through. So, I cut the damaged part away, soldered the wires back together, and insulated them with heat shrinks. However, when I then tested...

    Identifying locations of Solder-Balls

    Seems difficult to identify all the possible solder-balls that can result from SMT and Reflow processes. Also not always will all the solder-balls stuck to the bases of parts wash out. So then I guess only an additional visual inspection could identify them. But I'm wondering if the pixel-data...

    Soldering dead bug circuits

    Hi there, I have been working on an AM radio test generator. It is from the book ”building your own transistor radios”. I would provide a schematic of the circuit although I believe the copyright would prevent me from doing so. The two ICs used in the circuit are the 74HC14 hex Schmidt...

    What is this? I can't even get the solder to melt.

    I'm simply trying to learn and practice soldering and desoldering. I have an old board i am working on and can't for the life of me get ANY of the components off. I can't even get the solder to melt. Do they use something other than solder during manufacturing? Here is a picture. I have...

    Is this circuit board ruined?

    Is there a way to salvage this part of the board with soldering? When I was trying to unplug the connector that was attached to this board, I accidentally pulled the whole thing off (connector and it's 'housing', instead just the connector). So as you can see the part where the arrow points to...
