Workshop video #01: Sjaak solders a QFN chip, attempts the BGA challenge

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 tiny BGA chip, see how it turns out. Here’s some links mentioned in the video: […]

Arup’s DIY fine-pitch soldering technique

Arup started building his Nokia LCD breakout boards and shared his soldering technique for the 0.5mm pitch connector. First he aligns and fixes the connector in place with a bit of sticky tape. Next he applies some flux. Now the interesting part is that when he solders the connector he doesn’t use any additional solder. […]

Watch us solder the Bus Pirate v4. The Bus Pirate is an open source hacker multi-tool that talks to electronic stuff. For a comprehensive overview check out our previous post. Here are the main differences and advantages of V4 over V3: Integrated USB in the microcontroller (faster) Data storage EEPROM to hold settings Pull-up voltage […]

Soldering the Bus Pirate demo board v5

Watch us solder the Bus Pirate demo board v5. The simple process of making a demo board for the Bus Pirate turned out to be far more complicated then we expected. Previous versions used many different chips and turned out to be more expensive then the Bus Pirate itself. For version 5 Sjaak came up […]

Reflow soldering toaster oven

Frank wrote an instructable about a solder reflow oven made from a toaster: As I get more serious into my electronics hobby, I need to work with more SMD components. Some component packages are very difficult or impossible to solder with a traditional soldering iron. To solve this problem, I decided to hack a toaster […]

Professional techniques for hand soldering

BFX tipped us to this video of professional soldering techniques in the comments of our Soldering the 8bit PIC SchmartBOARD post. The video shows how to prepare, solder, and clean a board with SMT components. Amongst other things, this tutorial shows how to solder one side of a fine pitch QFP device in one swoop […]

Soldering the 8bit PIC SchmartBOARD

Here is a video showing how to solder a PIC16F88 and a few discrete components on a 8bit PIC SchmartBoard. The 8bit PIC SchmartBoard is a development board that supports many of Microchip’s 8bit microcontrollers in SOIC packages. It has a on-board crystal, 5v voltage regulator and 28 breakout pins for the PIC.  It also […]

HAKKO 907 and compatible soldering iron pencils

Arhi posted a roundup of HAKKO 907 (machine translation) soldering irons and compatible clones that are used with HAKKO 937 soldering stations. Hakko 907 replacement soldering irons are high quality and relatively cheap irons, and there are many compatible clones on the market. Arhi says there is only a slight build quality difference between the […]
