Andre shares this short article on how to make homebrew solder paste stencils from 0.1mm brass plates. Via the contact form.
jwhitley89 tweeted: “And this is how you solder 8 AWG wire with lead free”
This week we take a look at the 946A+ solder reflow hot plate from our last Shenzhen equipment haul. There’s a ton of no-name 946A+ out there, ours happens to be D-GOLD. They’re all pretty similar, and run about $50 … Read more
Joe Desbonnet writes in with two tips he learned when using the DP QFP breakout board. Via the contact form.
Xevel shows us how to solder fine pitch BGA dead-bug: After seeing a few posts about “deadbugging” (soldering wires to the leads or pads of a component instead of soldering it on its recommended footprint) of BGA chips on Dangerous … Read more
Andrew Tergis presents an interesting method of reflowing SMD components using a preheating plate and tinfoil (to catch infrared energy). He also uses a Fluke temperature probe attached to the PCB to more accurately monitor temperature. This gives newcomers to … Read more
Here is proof that soldering BGA’s is not that hard. Check out this Mandelbrot zoom fractal engine with a PSP display project (machine translation). The FPGA in a ball grid array package is soldered dead bug style. Now that’s skill. … Read more
Alex designed this soldering iron tip holder. It’s an aluminum bar bended into shape, with holes for the tips drilled into it. As basic as it is, it’s both functional, and good looking. After everything was said and done, it … Read more
Proper soldering iron maintenance and soldering techniques required to get a perfect solder joint every time. Via PCBheaven.
5 more new prototypes on the bench. First the big chips then the little stuff.
In our previous Workshop Video we mentioned we asked Pietja to solder up those pesky MMA7455L accelerometers. Here is how he got around to doing it. Check out the pics and his instructions below. Ian asked me to solder some … Read more
From IRC we bring you some pics of Robots’ mad soldering skills. This QFN chip is dead-bugged onto the back of another chip. Below there’s another QFN chip broken out with wire. Please send in your pics of extreme soldering … Read more
In an earlier Workshop Video we challenged Sjaak to solder a TMP006 non-contact temperature sensor in a BGA package. We lacked the skills to make it happen, but this week DP engineer Jer shows how he successfully soldered 2 of … Read more
Here’s another SMD soldering video tutorial. It features the use of 4 different flux types: pen, liquid, gel, and syringe. The video starts with soldering a 0603 chip resistor and moves up to a 208pin 0.5mm pitch QFP IC. Via … Read more
This app note from Texas Instruments covers the basic guidelines on how to solder QFN and SON lead-less package. It includes some PCB design, solder paste screen printing, assembly, and reflow guidelines. Quad flatpack no leads (QFNs) and small-outline no … Read more
Ball Grid Array chips have multiple rows of contacts under the chip. These are difficult to solder by hand, as we found out when Sjaak tried to solder a TMP006. Zeta tipped us to this video of hand soldering a … Read more
Kartik soldered the first prototype of his PSoC3 development board. He used a no-solder soldering technique to solder the SSOP IC. He had great success with this technique, after destroying a few PCBs with his old method. Things didnt go … Read more
We took our cameras on the road and visited Sjaak’s workshop this week. He showed us how he solders QFN chips with a bit of hot air and normal drag-soldering. We also surprised him with a challenge to solder a … Read more
