App note: Assembly guidelines for QFN (quad flat no-lead) and SON (small outline no-lead) packages

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 […]

Soldering pen

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 site.

App note: Soldering Tip Care and Use

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 […]

App note: “Is Your Soldering Equipment Speeding?”

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 […]

Soldering iron + Nodemcu = IoT device

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 server through WIFI. It also sends me Prowl messages on my Iphone when I forget to turn it off. It all […]

Soldering station to drive HAKKO 907 handles

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 […]

DIY soldering robot

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 […]

Soldering robot – Head assembly

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: […]

Hakko T12 soldering controller

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 […]

SMD soldering station for Weller soldering tips

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 […]

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 […]

Drag soldering for surface mount chips

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 […]
