by Henrik’s Blog @ hforsten.com:

Nowadays many of the most “exiting” chips come only in leadless packages, such as BGA and QFN which are hard or impossible to solder just by soldering iron, because leads are under the chip where they can’t be reached. These kinds of chips are usually soldered using reflow soldering. In reflow process solder paste is used instead of solder wire. It contains very small balls of solder in flux, diameter of the balls is just few micrometers. First this paste is put on the contact pads, then components are placed on the pads and whole board is heated in reflow oven where solder balls in the paste melt and attaches the components firmly in place.

This Reflow Oven Controller relies on an Arduino Pro Micro, which is similar to the Leonardo and easily obtainable on eb*y for less than $10, plus my custom shield, which is actually more like a motherboard.

As I believe it is not wise to have a mess of wiring and tiny breakout-boards for operating mains powered equipment, I’ve decided to design custom board with easily obtainable components.

The hardware can be found in the folder hardware, including the Eagle schematics and PCB layout files. It should fit the freemium version of Eagle

Hi, I recently built a reflow toaster oven using an Arduino. I know it’s pretty standard stuff, but my version has an automatic oven door opener (using a servo) and circulation fan to speed up the cooling time, and remote notification using an RF transmitter

Bill details how a microwave oven heats food. He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing how a magnetron generates radio waves.

Sorry for the lack of photos in this article, but we didn’t think about it being worth reporting until after it had all happened. Infact, we were concerned about retaining any evidence of the events. Inspired by the many toaster-oven reflow projects floating around the Internet, we set out to acquire the power to solder all those tiny SMD components ourselves. Toaster ovens aren’t that common in the UK and we were aiming for the lowest cost possible, so we hit ebay in search of a bargain. A very cheap Black and Decker Toast-R-Oven was on offer. The description was “only used a few times”, and the grainy photos showed an indeterminate “foreign” plug with an adaptor. Now, we aren’t generally in the habit of assuming that “some bloke on ebay” must know what he’s doing with electricals, but with the auction starting at £5 (and not going up a huge amount from there by the end) it seemed like a good idea.

One of SMD soldering techniques is using a reflow soldering oven. Reflow soldering technique is used when it is impossible to solder components by hand. These may include ball grid arrays (BGA), small pitch quad flat packs. Or simply solder any SMD element to make board look professional and smooth.

Special care has to be taken when soldering with oven. Specialized ovens have controllers built in that control overall soldering process by adjusting temperatures, but if you are using regular oven that is much cheaper than specialized soldering ovens, you need to build a controller. Controller has to adjust soldering oven temperature according to chart that is stored in memory. Together with keypad this gives great interactivity.

Soldering oven controller is based on ATmega32 microcontroller that uses ADC input to read NTC temperature sensor. Current temperature is displayed on graphical LCD as chart. As authors state – system works OK, maybe additional blower could be added for cooling speed controlling as without fan it is to slow. [via]
