soldering

I made this ‘fix’ about 7 years ago and the device is still in use today. I know which one it is because my 5ohm resistor came out around 4.9 so the device always runs 2% out of spec.

Yes, it worked perfectly! The repaired broken line was apparently power to the LED backlight.

This was the first time I’ve used a stencil and solder paste to build up a pcb. It was so much easier to get all the components aligned and soldered on the board (on the back, there are 38 0603 capacitors which are always time consuming to hand solder). After just had to clear a few bridges and added a little extra solder to...

I recently got this cheap USB dac thats plugged into my pc over USB - B but it still needs Micro USB power for some reason. So I thought I could just connect the 5V from the USB A port to the Micro usb’s. Is there any reason why this doesn’t work? https://files.catbox.moe/kb6syc.webphttps://files.catbox.moe/6u3g6t.webp

I’m working on replacing the Schneider SmartRelay on an Atlas Vista 613 wheelchair lift that I bought for my dad. The Atlas technician agrees that the SmartRelay is probably shot and the replacement is $1,000 wholesale. I built a replacement using an Arduino Nano, a UNL2803A Darlington array, a switching 7805, a bunch of Zener...

With maple syrup season fast approaching (4 months ish) my thoughts have turned to working on the Sapmaster once again. I’m going to design and build a new top and bottom board this year to fit in the BUD DMB-4774 DIN case that I use for the SapMaster controller. That’s going to involve a bunch of SMD soldering which...

I’ve posted a few videos now of myself soldering header strips and some SMDs with my good quality soldering tools and with an inexpensive soldering iron that I bought at Walmart. I sent a link to the friends, the hardware designed and programmer, who I often work with. One designs the boards, the other programs them. I do some...

In this video I go back to the beginning of my more than 45 years of experience soldering and buy a $15.88 Chinese soldering iron from my local Walmart store and compare it to a Weller PES51 pencil iron connected to my WESD51 soldering station and a Hakko FM-2027 connected to my FM-203....

Will it solder?...

What was I thinking?!?...

Will it solder?...

When I started soldering everything was big and had leads that went through holes in the board. You inserted the leads, bent them over to hold the component, flipped the board over, soldered everything, and trimmed off the excess leads....

I got myself a T12 clone station recently. I’ve only had a junk iron that plugs into a wall socket and heats up to full blast whatever temperature with the big giant tip. Not very useful for more precise work....

I am a beginner at soldering and am trying to assemble a number of these small pcbs. In the process, I have to solder SK6812 MINI-E LEDs and am struggeling to get that right. My problem is that the LEDs tabs are almost exactly as large as the solder pads on the PCBs and if I apply solder and flux to the pads and try to use hot...

I made a new video about why I love liquid flux and how much of a difference liquid flux can make to your soldering....

We often get asked what we think of beginners first soldering projects then offer suggestions how to improve their technique, and often, how to rescue their project....

In this video I solder an ATMEGA328PB in a 32-pin QFP with 0.8mm pin pitch....

In this video I solder two 16-pin header strips onto a QFP32 to DIP32 adapter board....

I’ve posted videos of myself soldering a SOIC8, a QFP32, and header strips. Is there anything else that anyone wants to see? Want to see me solder a QFP with a chisel tip instead of a GW tip? How I solder 0805 SMDs with a regular soldering iron? Want to see me reflow bad solder joints using a regular soldering iron and liquid...

First time soldering anying this small. Would love feedback, or tips

I few days ago in a comment here, or maybe in another community, I mentioned that I thought that soldering SOIC ICs was relatively straight forward to do with a regular soldering iron and a small chisel tip. I regularly solder SOICs and T/QFPs with nothing but a 1/6 mm chisel tip....

I did this last week before finding this group, so no pictures of my soldering. I take it that the purpose is intended to be general electronics?...

When I first started soldering my parents bought me a (probably < $10 at the time) hobby soldering iron. That iron took a beating and was replaced with another hobby iron then another. I ended up with a hobby iron that I absolutely loved. It had a powder blue handle, a solid barrel (not rolled sheet) and was flared where the...

This was an interesting repair. The little company that I work with discovered that one of the pins on the TQFP was not pulled out to the header on the breakout board. They needed that pin so they hired someone to desolder it, lift it, and solder a wire on the to cut the trace to one of the header pins and bring the wire out to...

Most of the projects I design start out on solderless breadboards. The one in the bottom of this picture is a ROM switcher and reset circuit for a Commodore 64 that I’m working on. This circuit will fit inside the footprint of a 27256 ROM chip in a 2364 to 27256 ROM adapter....
