soldering

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...

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...

Product: Pavilion 15-au146ng Hello guys, one pin of my rj45 port of my HP Pavilion 15-au146ng is broken off. Now i search for the port in the web to replace it by soldering. But i cannot find the correct type. Maybe someone of you knows where to search or even got a link for me to the product...

So I had my first soldering experience on my second computer mouse, idea was just to put in new microswitches. I began to do with my old thick soldering iron and now it looks like I applied too much heat and my solder pads GONE. I bought myself a new better soldering iron, but havent seen any...

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...

My friend has a broken blue snowball microphone and its powers by a mini USB cable plugged into a computer, the mini USB connector somehow broke off the board and has been rattling around its casing, I opened it up and found where its supposed to be connected, is this saveable? could I just...

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...

I'm working on a DIY project where I need to control some 9V solenoid valves with an arduino. I don't have the tools to make a PCB myself, so i choosed to work on perfboards. Now, I have to connect power supply (MeanWell ) to the step down regulator (Polou D36V50F9) that powers the solenoid...

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...

So guys the display ribbon cable on my JVC KD-AVX44 went bad, and I was wondering if I can find something similar, or if it's just a proprietary cable, that only JVC uses. It's a 24 pin ribbon cable with a regular termination on one side, but on the the other it's split into two 12 pin...

Quarantine project: Adapting a Sony BFV-20W viewfinder Scroll down to skip the background info As a cinematographer, I've always really felt most comfortable shooting with a viewfinder. However modern electronic viewfinders all exist in the "prohibitively expensive" class of filmmaking...

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...
