The paintbrush technique for low temp solder
Log from Assembling dense SMD PCBs - lessons learned
I got this tip from someone else when I had to assemble my first 0201 board. It seems a bit weird at first glance, but it works very well! The Idea Your solder might come in paste form, but it doesn't have to be in that state when you place the components....

Solder paste printing, assembly and reflowing
Log from Optically Isolated USB-UART Adapter
The solder paste is applied using a stainless stencil from oshstencils.com. These stencils are very nice and easier to use than plastic stencils. Result in next picture. All the parts layed out. I use a home made vacuum pickup tool to place the parts....

Bobble Build: Part 1 - Solder on!
Log from Bobble-Bot
New PCBs are in, time to start soldering on components! The board we're going to cover in this post is the PDU (Power Distribution Unit). When it comes to LiPo batteries, I always try to stay on the safer side of things when I can,...

solder-proto for the next-generation
Log from sdramThingZero - 133MS/s 32-bit Logic Analyzer
Apparently it's brain-dump time.In the previous log I showed my thoughts on making a sorta general-purpose prototype-board that can be used for the first soldered prototype, as well as be used/usable for many other unrelated projects...Here's the latest...

How to configure User key with solder jumpers (SJ1/SJ2)
Log from ESP-01 NanoBoard (ESP8266)
The User key can be configured to act as the FLASH key of the nodeMCU (key connected to ESP-01 GP0IO) or as a generic user key connected to the GPA1 port of the GPIO expander (MCP23017). Using Arduino IDE the second choice seems to be better, of course...

More parts coming in, solder problems and a fail
Log from cheap versatile High vacuum chamber
So, I made a lot of progress with sanding disc/ angle grinder drill press and ball bearing , but this technique was very frustrating. I caved and gave the base plate to a friend to face in their lathe: They look great.I also have a couple of stainless...

Order PCB and solder parts on the board
Log from Veterobot
The whole set of Eagle files (including libraries designed with EAGLE6.3 Lite) to ordert the PCB is available in veter-caprepository. For our boards, we are currently using services from PCB-POOL. You might consider different PCB manufacturer depending...

Solder paste wont be easily cleaned from PCB after reflow in oven
Log from Lifetime fails project
This is just a quick starter or project icebreaker :) Maybe more fun, but in reality it was fail because I was very naive thinking I will spread thin layer of solder paste all over the PCB, place all the components and reflow it in oven and clean all...

Soldering components to the PCB and teaching YOU how to solder
Log from The UnbreakaBLE Micro Drone
I am going to have an horrendous time soldering this PCB. I have soldered SMD passives before, and I find them generally pretty easy, but I have never soldered QFN before, and this is my first time. I will document my journey of soldering QFN components...

Combining high-temp and low-temp solder on the same board
Log from Assembling dense SMD PCBs - lessons learned
Here's a mixed alloy board with a switch in the top right corner, a little BGA, and a u.Fl connector (not visible, but it's there! I promise). Those have high temp solder, the rest is low temp and not even completely done. I'll save that for later so...

if you need to replace sensor, solder a new one on from digikey
Log from mlx90640 sensor works w 800 bytes
i had damaged a sensor 110 deg x 75 deg, which is about 80$ and shipping. i did this when experimenting with the highest frequencies. chip spec is 1mhz. i ran above this testing it. for reading ram it seemed ok. it corrupted data somewhere...

Fixing a cheap solder sucker when you don't have a suitable replacement O-ring
Log from Creative repairs and hacks
A cheap solder sucker I got some time ago lost the ability to pull a vacuum. The O-ring on the plunger failed to made a good seal. the slightly bent shaft may be partly to blame for this. The easiest solution would be to use a larger o-ring...

Soldering components to the PCB and teaching YOU how to solder Part 2
Log from The UnbreakaBLE Micro Drone
The last log is downright easy compared to what we must accomplish now. Soldering a large 44 pin QFN package might've seemed difficult, but soldering the QFN IMU sensor is a different league. I might be exaggerating the difficulty because I am...

#9 - Setbacks, or how Pb-Free solder paste ruined my protos
Log from MAD - Modular Audio Devices
Quick update: I ruined my first batch of protos. I received the PCBs, real beauties; I received all the components, and I received TWO kinds of solder pastes: a ChipQuik low melting point one, and a CIF lead-free because enviromental concerns...

Learning How to Solder (a.k.a. How on earth does all of this still work?)
Log from Tea-Pi
Now that I've finally gotten all of the parts it's time to see if I can jam them together through mostly guesswork + a vague idea of what soldering is that has been garnered from random youtube videos. First I assembled the Pi Plate. This was my first...
