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. […]
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 […]
Hacker Camp Shenzhen volume 3: “Reflow” is on! Join us from Thursday December 4 to Saturday December 6, 2014 for fun, food and 3 solid days of market tours in Shenzhen China and beyond. Tickets are available now. Come to the world’s electronics capital and experience Shenzhen like a local hacker. Tour the famous Huaqiangbei […]
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, […]
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.
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.
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.
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.
