David Sanz Kirbis built his own reflow device with an halogen floodlight, that is available on Github: First test was to check the speed of the temperature rise inside a standard halogen floodlight. Reflow soldering temperature curves are quite demanding, and some adapted ovens can’t reach the degrees-per-second speed of the ramp-up stages of these curves. […]

An Android reflow controller that anyone can build
Andy Brown published a new build, an Android reflow controller: The only surface mount device on this PCB is the MAX31855 and it has a low number of generously spaced pins. I eschewed my hot air gun, previous reflow oven and hot plate in favour of a plain old iron and the tack-soldering method because […]

WORKSHOP VIDEO #59: 946A+ solder reflow hot plate
This week we take a look at the 946A+ solder reflow hot plate from our last Shenzhen equipment haul. There’s a ton of no-name 946A+ out there, ours happens to be D-GOLD. They’re all pretty similar, and run about $50 in Shenzhen. Using a kitchen hot plate is a common hack for DIY reflow soldering, […]
Hot plate reflow test 1 and 2
Reflowed two 0805 caps on two qfp protoboards. One at 250 and one at 240c.p Both took about 30 seconds to reflow. Anyone know the optimal temp for crappy old lead solder paste? Board at 250 looks scorched but that could be from the reflow oven instead. Will do a second test to find out.
Simple surface mount reflow process done at home
This video explains a simple reflow PCB assembly technique. The board is first prepped with solderpaste using a stencil. Then a manual pick and place machine populates the board. This is followed by a 5-6 minute cook in the reflow oven.
Preheating plate + tinfoil = almost reflow
Andrew Tergis presents an interesting method of reflowing SMD components using a preheating plate and tinfoil (to catch infrared energy). He also uses a Fluke temperature probe attached to the PCB to more accurately monitor temperature. This gives newcomers to reflow an idea of the pitfalls involved. Vladimir via the contact form.
Open Logic Sniffer on Ask an Engineer Chat
We spotted an Open Logic Sniffer in Adafruit’s weekly Ask an Engineer Chat. It looks like they’re soldering it up on a reflow plate. We like the warning that the reflow plate may be a hot surface.
