An Android reflow controller that anyone can build

Monday, August 24th, 2015

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...

WORKSHOP VIDEO #59: 946A+ solder reflow hot plate

Thursday, March 14th, 2013

[embed]http://www.youtube.com/watch?v=2gkZX0r4cvQ[/embed] 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...

Hot plate reflow test 1 and 2

Thursday, January 31st, 2013

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...

Simple surface mount reflow process done at home

Wednesday, December 19th, 2012

[embed]http://www.youtube.com/watch?feature=player_embedded&v=U48Nose31d4[/embed] 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

Tuesday, November 13th, 2012

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...

Open Logic Sniffer on Ask an Engineer Chat

Monday, March 1st, 2010

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.
