Martin Kumm writes: This page provides documents about a cheap SMD solder station built as an Arduino shield (Arduino UNO). It supports active soldering tips from Weller (RT series) which contain the heating element as well as a sensor and … Read more
By ian QFN, BGA, plastic connectors, other crazy advanced removal and replacement of surface mount components by a teacher at a Lande Mobile Repair School in Shenzhen China. Part of Hacker Camp Shenzhen 2014. Presentations, pictures, and overview here. Next … Read more
This video by Oliver Krohn demonstrates how to solder SMD parts on hot sand: Soldering on hot sand using a bunsen burner or frying pan / oven. In this case I bought a SOIC breakout board and had to solder the chip onto it. … Read more
This video by Steve of Big Mess o’ Wires demonstrates how to solder a 44-pin chip in a typical TQFP package using the drag soldering technique: The process begins by applying a liberal amount of flux to the pads, then positioning the chip on … Read more
Here’s a graphical app note from TDK on the phenomenological “tombstone” when doing reflow soldering. If temperature and solder quantity is inappropriate during substrate mounting, products may not be mounted properly, which causes tombstone
Things you might need to know about doing SMT rework on Multi Layered Ceramic Capacitors (MLCC). An application guide from TDK Rework is necessary when surface mount (SMT) components become misaligned or improperly mounted. This paper will answer questions concerning … Read more
Mats continues his challenge of designing one PCB every week. In week 18 he came up with SMD Practice Skull: I while ago I chatted with (Re:load) Nick Johnson about making some simple pcbs for learning how to solder smd … Read more
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
