NXP’s app note about the internals and how to’s footprint design and solder their leadless dual and quad flat packages. Link here (PDF) The small outline no-lead (SON)/quad flat no-lead (QFN) is a small size, lead-less plastic package with a low profile, moderate thermal dissipation, and good electrical performance. It is a surface mount package […]
MSOP-10 soldering video at mitxela.com: I admit that when I made the video of me soldering an MSOP-10 package, I did it because I needed to use the chip right away, and didn’t have time to order a breakout board. But this time, I am just doing this for fun. MSOP is smaller than TSSOP which […]
Facelesstech published a new build: So you are using a bare attiny85 in your next project but don’t have room for the programming header, What do you do? I came up with the idea of using pogo pins layed out on A PCB so that they will sit on top of the Attiny85 legs. I […]
Facelesstech published a new build: So when I was into using just a atmega328 dip chip I make a programmer header for it that also had a crystal and the capacitors need to make it function. I wanted to do the same for the attiny85. As you know you have to use a ISP programmer […]
zed65 posted picture of his UniSolder 5.2 build designed by Sparkybg: Ok, first of all thanks sparky for a great project! I’ve now finished the project and it finally works. Thought I would share some of my experience when building this. Via the project log forum.
In this video Hans Peter demonstrates his soldering pen project: I’ve tried to compile a list of the things I still need to finish (not in order): – making a stand – making a casing – make temperature control via buttons – slow down LED pulse – general cleanup (in HW and FW) Project info at embryonic.dk site.
In this video Dumitruv demonstrates his Unisolder 5.2 designed by Sparkybg: First part is the calibration with a precise 10 Ohm resistor then I plug the iron and you can see the temperature stabilizing after quite awhile. Once it stabilizes I touch the wet sponge and it goes out of whack again. Via the project […]
A quick app note from Weller on soldering tip care. Link here (PDF!) When it comes to soldering irons, you know that the tip is the most critical component. While the soldering iron holds and heats the tip and controls its performance, the tip is tasked with the most important job of transferring heat efficiently […]
A technical note from Weller on how accurate your soldering tool reading are. Link here (PDF!) With so many technological advancements, there is no excuse for incorrect measurement readings. For example, your automobile has a number of alternative methods to check the accuracy of the speedometer. You rely on those indicators to be accurate. If […]
SZ64 posted picture of his soldering controller PCB build in the project log forum: Hi sparkybg, You have indeed perish in labor ;-) Just say that you are well. I managed to finally all up and running as it should. Via the forum.
Vegard Paulsen blogged about his soldering-iron #IoT project: My trusty old soldering-iron recently got an upgrade! With the help of a NodeMCU. a RGB-LED it now reports the set temperature to the #IoT Thingspeak.com server through WIFI. It also sends me Prowl messages on my Iphone when I forget to turn it off. It all […]
Dilshan Jayakody published a new build: To keep it simple we choose LM358 dual operational amplifier IC to monitor the 907’s thermocouple and drive the TRIAC. The entire control circuit of this soldering station is powered by single rail 5V DC power supply. To drive both handle and station we use 12V-0-12V 8A step down […]
sparkybg shared his universal soldering controller in the project log forum: The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: – power: […]
Here’s Brian Dorey’s completed project the DIY soldering robot project. We wrote about it previously: The DIY soldering robot which we have been building in our spare time over the past few months is now working and we have been able to solder some test Raspberry Pi expansion board headers with the machine. Project info at […]
Brian Dorey published a new build, a soldering robot project: We have finished the soldering iron element slider system and stepper mount for the new soldering robot project. The soldering iron element slides on a pair or 6mm rails, drylin® accessories, precision aluminium shaft 100mm length (part no: AWMP-06) with drylin® R – Bearings (part no: […]
Diogoc shared his Hakko T12 soldering controller in the project log forum: I finally finished my Hakko T12 soldering controller. Thanks to sparkybg and arhi for all help and sugestions. Some features of the controller: – 3310 graphic display – rotary encoder for easy and fast temperature selection – sleep mode when the iron is in the […]
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 provides a standard 3.5 mm jack. Together with the corresponding female connector you will get […]
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 week we’ll have step by step instructions for reballing BGA chips. Get your BGA reballng […]
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. Via Hacked Gadgets.
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 top. I use a pencil eraser to hold the chip steady while I tack down […]
